<H3>Building and Installing ACE and Its Network Services</H3>
<H4>Synopsis</H4>
The file explains how to build and install ACE and its Network
Services on the various OS platforms and compilers that it has been
ported to. Please consult the <A HREF="ChangeLog">ChangeLog</A> file
to see whether any recent changes to the release will affect your
code. You also might want to read the ACE <A
HREF="http://www.cs.wustl.edu/~schmidt/ACE.FAQ.html">FAQ</A> before
building and installing ACE. In addition, you might want to check out
our <A
HREF="http://www.cs.wustl.edu/~schmidt/ACE-development4.ps.gz">development
process</A>, as well. And as you start working with ACE, you might
want to consult the <a href="docs/ACE-FMM.html">ACE Frequently Made
Mistakes page</a>. If you encounter any problems or would like to request
an enhancement, then use our
<a href="docs/usage-bugzilla.html">bug tracking system</a> to submit a report.<P>

<P>Any UNIX/POSIX/Win32 variation is a potential target platform for
TAO. If you have <A HREF="docs/ACE-porting.html">porting
questions</A> or have a problem compiling the ACE wrappers on the
platforms shown above please send email to either <A
HREF="news:comp.soft-sys.ace">ACE Newsgroup</A> or the <A
HREF="mailto:ace-users@cs.wustl.edu">ACE mailing list</A> and we'll
try to help you fix the problems.

<LI><B>Win32 (Windows NT/i386, NT/Alpha and Windows '95) </B><P>
All of ACE has been ported to the Win32 API (which includes
Windows NT, Windows 2000, and Windows '95/98). The entire
release now compiles using the Microsoft Visual C++ 5.0, and
6.0 compilers. ACE can be built as both a static (LIB) and
dynamic (DLL) library, using the Win32 installation process
described below.<P>
Please see the <A HREF="#Non-static Object Manager">Non-static
ACE_Object_Manager</A> discussion below.<p>
We've also added some support for Borland C++ Builder 4.0 and
IBM's VisualAge C++ compiler. Since we don't have these
compilers we rely on the ACE+TAO users community to maintain
these ports. Therefore, please send email to the ACE mailing
list if you run into problems. <P>
<li><b>Windows CE</b><p>
Take a look at (<a href="docs/CE-status.txt">CE-status.txt</a>) for
up-to-date information about ACE on CE. <P>
<LI><B> Sun OS 5.x/4.x (a.k.a. Solaris 2.x/1.x, Solaris 7) using Sun
CC 3.0.1, Sun C++ 4.2 and 5.x, Centerline C++ 2.x, GNU gcc 2.7.x
and later (except 2.8.x), and KAI C++ 3.3/3.4.</B><P>
All the source code and tests should build and run without any
problems on Solaris 2.5.1, 2.6 and 7 platforms using the Sun C++
compiler. We use this version/patchlevel of Sun C++:<p> <pre>
CC: WorkShop Compilers 4.2 21 Apr 1997 C++ 4.2 patch 104631-02
</pre><p>
There are likely to be build problems with older versions or
different patchlevels of Sun C++.<p>

The home page for Sun technical patches is <a

Searching for 104631 will bring you to a page allowing you to
access the latest version of the C++ 4.2 patches.<p>
By default, ACE uses both the Solaris and POSIX thread
interface. To disable use of the Solaris thread interface, add
<code>-D_POSIX_PTHREAD_SEMANTICS</code> to the
<code>CFLAGS</code> in your
<code>ACE_wrappers/include/makeinclude/platform_macros.GNU</code>.
See the Solaris Intro (3) man page for more information.<p>
To disable ACE thread support completely, build with the
<code>threads=0</code> make flag. See the <a
href="#flags">Makefile Flags</a> section below for more
information on make flags.<p>
If you use g++ or egcs on Solaris 7, you might need to rebuild
it on a SunOS 5.7 (Solaris 7) host. Some versions of g++ and
egcs provide replacements for system header files. The
replacements on older SunOS systems are not compatible with the
SunOS 5.7 system headers. See <a
href="http://www.cs.wustl.edu/~levine/Hints.html">David Levine's
Hints page</a> for instructions on how to build egcs on a SunOS
5.7 host, using a g++ or egcs that was built on an older SunOS
host. <P>
The Sun/C++ 5.0 compilers has several problems with templates,
we have worked around most of them but this is not a compiler
that we test very often. Hopefully as new patches for the
compiler show up we will be able to make that our compiler of
choice on Solaris.</p>
<LI><B>Sun OS 4.1.x using Centerline C++ 2.x, Sun CC 3.x, and Lucid
Energize 3.2.</B><P>
Note that shared libraries do not interact very well with
Centerline C++ or Sun C++ on SunOS 4.1.x. This is due to odd
behavior of the SunOS 4.1.x linker, which (1) does not properly
call constructors of global objects within shared libraries and
(2) does not call the init() and fini() functions in shared
libraries, even though the manual claims that these functions
are called! In particular, this means that the tests in the
directory $ACE_ROOT/tests/Service_Configurator/IPC-tests/server/
will not work for statically linked services.<P>
Some versions of SunOS 4.1.x do not contain the
/usr/lib/libnsl.a library. This library seems to be optional
since System V Transport Layer Interface (TLI) support is
optional on SunOS 4.1.x (in contrast, it's the "preferred"
transport interface on Solaris).<P>
The best work-around for now is probably to either add a dummy
libnsl.a in /lib (which may not be feasible) or simply comment
out the line:<P>
LIBS += -lnsl<P>
in the
<CODE>$ACE_ROOT/include/makeinclude/wrapper_macros.GNU</CODE>
file. Naturally, any programs, e.g., the TLI_SAP tests, that
use the TLI wrappers aren't going to work!<P>
Note that on SunOS 4.x you may get warnings from the linker that
"archive has no table of contents; add one using ranlib(1)" for
certain libraries, e.g., libASX.a, libThreads.a, and libSPIPE.a.
This occurs since SunOS 4.x does not support these features.<P>
<LI><B>AIX</B><P>
The ACE port to AIX assumes that the user has installed the AIX
patch containing the dl*() APIs. To use these APIs, IBM has
created a separate product (free to AIX licensees) called shared
library hookable symbols (or slhs/6000). If you don't have this
patch, the sv* commands for compiling and linking will not be
present on the system.<P>
If you are using AIX 4.2.1 or later, this patch isn't needed;
the dynamic library APIs are included in the base operating
system.<p>
However, another patch may be needed. Thanks to
Susan Liebeskind <shl@janis.gtri.gatech.edu> for submitting
the following useful information:<p>
When building on AIX 4.2.1, using the xlC V3.1 compilers, you may
get the following error when building the ACE shared library.<p>
<pre>
makeC++SharedLib_r -p 0 -o libACE.so -bI:/lib/pse.exp -L/usr/local/src/ACE_wra
ppers/ace -L./ -ltli_r -ldl libACE.a
ld: 0711-317 ERROR: Undefined symbol: .__CurrentException
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
make: *** [libACE.so] Error 8
</pre>
To fix this error, you need a patch to the supporting xlC
related libraries. To obtain this patch, go to the <a
href="http://service.software.ibm.com/support/rs6000">IBM public
patch website</a>, and retrieve the patch PTF U453697, or its
successor, for xlC.<p>
You may wish to retrieve this patch with the fixdist tool, also
available at the website. Installation of this patch will
install patched versions of the C++ libraries, which correctly
define this symbol.<p>
To build ACE on AIX with Visual Age C++, use the
$ACE_ROOT/ace/ace-dll.icc (or ace-lib.icc) along with the appropriate
version-specific config file (e.g. config-aix-4.3.x.h). All of the
version-specific config files set the version number macros and
include the general config-aix-4.x.h file which has support for all
of the OS versions and compilers supported on AIX. Using the general
config file is the recommended practice for egcs, C Set++, and IBM
C/C++ compilers. However, the Visual Age C++ compiler does not make
use of the platform_macros.GNU file, which is how the OS version
information generally gets set.<p>
BTW, here's a technique from Rob Jordan <<A
HREF="mailto:jordan@hursley.ibm.com">jordan@hursley.ibm.com</A>>
that can reduce the size of the ACE libraries by about one
third, and can also be applied to applications. It works by
optimising the sharing of template functions, which are created
in an "unusual" way under AIX. It also speeds up
compilation.<P>
Here's how to optimise the ACE library generation:<P>
Look at the <A
HREF="ace/Makefile">Makefile</a>
in <CODE>$ACE_ROOT/ace</CODE>. Create a file called
<CODE>ACE_All_Src.cpp</CODE>, and add a line to #include
each of the source files
listed under <CODE>FILES=</CODE> in the Makefile. Create a
file called <CODE>ACE_All_Tmp.h</CODE>
and add a line to #include each of the .h files listed under
<CODE>TEMPLATE_FILES=</CODE> in the Makefile. Now update the Makefile so that
<CODE>FILES=ACE_All_Src</CODE> and <CODE>TEMPLATE_FILES=ACE_All_Tmp</CODE>.<P>
<LI><B><a name="Linux">Linux</a></B><P>
ACE has been ported to <A
HREF="http://www.cs.wustl.edu/~cleeland/ace/">Linux</A> on
Intel, Alpha, and PowerPC platforms. If you use a RedHat 5.x
distribution, it's best to use RedHat 5.1 or later. ACE works
without any modifications on RedHat 5.1 and later, and on
Debian 2.1 on both Intel and Alpha. Make <A
HREF="#unix">symbolic links</A> to the
<code>include/makeinclude/platform_linux_lxpthread.GNU</code>
and <code>ace/config-linux-lxpthreads.h</code> as your
platform_macros.GNU and config.h files, respectively. The same
files can be used on PowerPC, with LinuxPPC
1999 (R5), with glibc 2.1.1.<p>
If you run out of memory, it's easy to add virtual memory on
Linux. Please see the <code>mkswap</code> man page. You'll
need around 256 to 300 Mb of virtual memory (RAM + swap) to
compile all of ACE+TAO. The <a href="#resource_requirements">System
Resource Requirements section</a> has some suggestions on how
to reduce the memory requirement.<p>
The glibc 2.0 dynamic loader isn't thread safe. If you want to
use the Invocation API you'll have to set
<code>LD_BIND_NOW=true</code>. If you want to use
<code>dlopen</code>, you should use <code>RTLD_NOW</code>. The
dynamic loader in glibc 2.1 is thread safe.<p>
The ACE <code>Tokens_Test</code> hangs with egcs 1.1b on Linux.
It runs properly when built with egcs 1.0.2 and later. All other
ACE tests run properly with these egcs 1.0.2 and later.<p>
<strong>NOTE:</strong> The TAO NameService uses IP multicasting
by default, though it is not required. IP multicast on Linux
requires the following:<p>
<ul>
<li>Enable IP multicast in the Linux kernel. It is enabled in
the default RedHat 5.1 kernel. In older distributions, you
can enable it by rebuilding your kernel with CONFIG_IP_MULTICAST
enabled.<p>
<li>Enable IP multicast in ACE. It is enabled by default in
<code>ace/config-linux-common.h</code>. If you don't use
IP multicast, add <code>#define ACE_HAS_IP_MULTICAST 0</code>
to your <code>ace/config.h</code> before building ACE.<p>
<li>There must be a network interface that is up and supports
multicast. If you have linuxconf, it's easiest to use that
to add a network route for multicast (224.0.0.0) on one of
your network interfaces, such as <code>eth0</code>. If
you don't have or use linuxconf, try adding a multicast
routing table entry using something like this:<p>
<pre>
<code># route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0</code>
</pre><p>
</ul>
With RedHat 5.0, you'll need some <a
href="os-patches/linux-patches.html">updates and possibly some
patches</a> to get ACE working with LinuxThreads. Some of the
patches are necessary with Alpha CPUs and with some older
kernels. egcs 1.0.1 can also be used, but it may need patches,
described there, as well.<p>
<strong>NOTE:</strong> Be careful when installing egcs on RedHat
systems. If you don't remove your old gcc and libg++ RPMs, it's
best to install egcs in a different directory than
<code>/usr</code>, such as <code>/usr/local</code>, and set your
<code>PATH</code> and <code>LD_LIBRARY_PATH</code>
accordingly.<p>
Some of the ACE tests fail on older, pre-glibc2 Linux platforms,
such as RedHat 4.2. The problems are with threads and
thread-specific storage.<p>
<LI><B>SCO UNIX</B><P>
ACE has been ported to SCO UNIX using the GNU g++ 2.7.2
compiler. Arturo Montes <<A
HREF="mailto:mitosys@colomsat.net.co">mitosys@colomsat.net.co</A>>
maintains this code. In addition, he also maintains a version
of <A HREF="FSU-threads.tar.gz">FSU pthreads</A>.<P>
<LI><B>SGI IRIX 5.x and 6.x</B><P>
ACE used to build fine using the SGI C++ and GNU GCC compilers
for IRIX 5.x. It has been ported to IRIX 6.x using the SGI
MipsPro 7.1 C++ compiler; be aware that in IRIX 6.2 there is a
number of patches that have to be installed and exceptions
appear to fail with the O32 ABI. Please check the config files
for the details.<P>
<LI><B> HP-UX 9.x, 10.x, and 11.00 </B> <P>
HP sells 2 C++ compilers for HP-UX 10.x and 11.00. If you are
using 9.x, there's only the first one.
<UL>
<LI>HP C++ - this is CC, HP's cfront-based compiler. As of ACE 4.4, it
can be used, but some people have problems with templates.
Caveat emptor. It's been said that you should run version 10.24,
if not later.
<LI>HP aC++ - this is aCC, HP's new, ANSI compiler. It handles ACE
pretty well. You should use version A.01.18 (or higher) on
HP-UX 10.x and version A.03.13 (or higher) on HP-UX 11.00.
</UL>
<P>
On HP-UX 10.20, a patch is required to compile ACE. The exact patch
number depends on the platform - check with HP's patch database to
locate the exact patch or its successor. For 9000 700 series machines
it is PHKL_8693 (s700 10.20 sys/time.h fix for select(2)/C++ defects).<p>

<P>
<LI><B>OSF/1 3.2 and 4.0 (a.k.a. Digital UNIX 4.0)</B> <P>
The Digital UNIX C++ 5.4 through 5.7 compilers have problems
with ACE's templates. They compile the lib and most of the test
programs, although they warn about template usage. Most tests
run, some dump core. If you use a 5.x version of cxx, be sure
to set the CXX_VER variable to CXX_5, either on your make
command line or in an environment variable. The ACE Makefiles
assume by default that the cxx version is 6.x or later.<P>
CXX 6.0 and 6.1 are much improved over 5.x: V6.0-020, V6.1-025,
and later build all of ACE cleanly. All of the tests in
ACE_wrappers/tests run successfully with CXX 6.0 and CXX 6.1.
Please note that problems have been reported with some versions
of CXX 6.1, notably versions -021 and earlier. It's best to use
V6.1-022 or later.<p>
NOTE: if you use Digital UNIX 4.0f or later, you <strong>must</strong>
use <code>ace/config-tru64.h</code> instead of
<code>ace/config-osf1-4.0.h</code>. <code>ace/config-tru64.h</code>
can be used for all supported compilers on any version of
Digital UNIX after and include 4.0. And, with 4.0f and later when
using Digital CXX, you <strong>must</strong> use
<code>include/makeinclude/platform_tru64_cxx.GNU</code> instead of
<code>include/makeinclude/platform_osf1_4.0.GNU</code>.
GNU gcc 2.7.2.1 compiles without problems. All tests run
(besides minor problems). Thanks to Thilo Kielmann <<A

<li><b> FreeBSD </b><p>
FreeBSD is a fast evolving platform. However, it has the
advantage of having standard releases. At this moment, ACE is
only perodically tested against -stable (3.1R) and we rely a lot
on FreeBSD users' feedbacks. <p>
Notice that on older FreeBSD, <code>ld.so</code> only looks for
so libraries with <b>version number</b> appended. ACE makefiles
create symlinks for most shared libraries if
<code>versioned_so</code> is defined to 1 in
<code>$ACE_ROOT/ace</code> with appropriate ACE version.
However, this does not work for libACE.so itself so you have to
create it manually (If you figure out how to do this, please let
us know) like this: <p>
<code>ln -sf $ACE_ROOT/ace/libACE.so $ACE_ROOT/ace/libACE.so.4.5</code><p>
On newer FreeBSD (3.0 or later,) this is no longer necessary.<p>
<li><b>NetBSD</b><p>
Like older FreeBSD, NetBSD's <code>ld.so</code> also requires
versioned .so files.<p>

Building ACE (and TAO) on Unixware 7.1.0 requires a very specific
g++ build environment. In particular, you must build and install
g++ 2.95.2, along with binutils 2.9.1. The order (and the declaration
of configuration) is extremely important. Using the gcc compiler
provided on the Skunkware CD on a pentium system, here is the recipe
I used to build a working environment (as root):<br>
<pre>
mkdir /usr/local/newgnu
< ftp and untar binutils-2.9.1 >
< ftp and untar gcc-2.95.2 >
mkdir -p build/binutils build/gcc
cd build/binutils
../../binutils-2.9.1/configure i386-sco-sysv4
gmake # takes a long time
gmake install # this creates /usr/local/i386-sco-sysv4/...
mkdir /usr/local/i486-pc-sysv5/bin
cd /usr/local/i486-pc-sysv5/bin
for a in /usr/local/i386-sco-sysv4/bin/*; do ln -s $a .; done
#links all the newly installed utilities
cd /usr/local/newgnu/build/gcc
../../gcc-2.95.2/configure --with-gnu-as --with-gnu-ld
gmake bootstrap # takes a long time
gmake install
mkdir /usr/local/i586-UnixWare7.1.0-sysv5/bin
for a in /usr/local/i386-sco-sysv4/bin/*; do ln -s $a .; done
</pre>
Once done, ACE and TAO will successfully build and link.<p>

<LI><B><a name="LynxOS">LynxOS</a></B><P>
ACE builds and runs properly on LynxOS 3.0.0 for Intel and
PowerPC targets.
ACE's Naming_Test fails; it is disabled in <a
href="tests/run_tests.sh"><code>ACE_wrappers/tests/run_tests.sh</code></a>.<p>
If you run out of memory on LynxOS, these might help:<p>
<ul>
<li>Increase the limits in <code>/etc/starttab</code>,
then logout and login again. We use these limits:
<pre>
# Data, stack, and core file limits (in Kbytes)
240000
80000
102400</pre><p>
<li>Enable or expand virtual memory, with something like:
<pre>
# mkcontig /swap 320
# prio 17 vmstart /swap</pre>
See the <code>mkcontig</code> and <code>vmstart</code>
man pages, and <code>/bin/rc</code>.<p>
</ul>
Please see the comments in the
<a href="include/makeinclude/platform_lynxos.GNU">ACE
platform_lynxos.GNU file</a> for information on, and an
example of, tailoring for your particular platform.<p>
We actively maintain ACE on LynxOS 3.0.0. It should build and
run on LynxOS 2.5, but we no longer test on that OS version.<p>
NOTE: if you want to use IP multicast on LynxOS, be sure to add
this line to your <code>/net/rc.network</code>, and reboot:<p>
<pre><code>
/bin/route add "224.0.0.0" "$my_name"
</code></pre>
Dave Mayerhoefer <<A
HREF="mailto:davem@lynx.com">davem@lynx.com</A>> has ported
ACE to LynxOS 2.5 using GNU g++ 2.7.2. However, you may need to
apply some <A HREF="os-patches/lynxos-patches.html">patches to
LynxOS</A> to get ACE working.<P>
<LI><STRONG>VxWorks</STRONG><P>
<A HREF="http://www.cs.wustl.edu/~levine/">David Levine</A>
<<A
HREF="mailto:levine@cs.wustl.edu">levine@cs.wustl.edu</A>> has
ported ACE to VxWorks 5.2/5.3/5.3.1/5.4 with the GreenHills
1.8.8/1.8.9 and g++ compilers that are distributed with
VxWorks/Tornado. An anonymous contributor has also
provided <a href="os-patches/vxworks-5.1.txt">notes for using
ACE with VxWorks 5.1.</a><P>
Tornado II/VxWorks 5.4 support IP multicast. That is not enabled
by default in ACE for VxWorks, because it probably depends on
kernel configuration. To enable it, add
<code>#define ACE_HAS_IP_MULTICAST</code> to your
<code>ace/config.h</code>.<p>
In addition to all of the other benefits of ACE, it helps work
around some deficiencies with VxWorks 5.3/5.3.1. Some of these
apply only with g++, at least thru version 2.7.2. That is the
version that is shipped with Tornado 1.0.1/ VxWorks 5.3.1. The
problems are:<P>
<OL>
<LI>The program entry point cannot be called "main" with g++. ACE
renames it to "ace_main" (configurable via ACE_MAIN) on VxWorks.
While this may seem trivial, it is important with legacy code.
ACE itself ran into this problem.<P>
<LI>argc/argv isn't used with VxWorks entry points. ACE provides
a wrapper function that transparently converts shell command
line arguments to argc/argv form. See <A HREF="#spa">below</a>
for details.<P>
<LI>Unsigned long long support is not available with the g++ that
is distributed with Tornado 1.0.1/VxWorks 5.3.1, or with
GreenHills 1.8.8. The documentation says that it is supported
by g++, but try using it :-) Wind River technical support verified
that it doesn't work. ACE provides its own 64-bit unsigned integer
type, ACE_hrtime_t, so you don't even have to worry about this
problem if you use it.<P>
<LI>There a gory problem with munch that is severely aggravated
by the presence of a static in the Wind River/g++ iostream.h.
ACE hides this and provides an easy-to-use workaround in the
very unlikely situation where it becomes a problem.
Please see ace/config-vxworks5.2-g++.h for more information.<P>
</OL>
In addition, as noted <A HREF="#g++">below</A> following the
discussion of the g++ -fno-implicit-templates option,
-fno-implicit-templates is broken for x86 targets. And, -O2
is not supported on some targets.<P>
Please note that ACE uses one of the spare fields in the Wind
River task control block, spare4, for thread- specific storage.
This field is specified in only one place, in ace/OS.i, so it
can easily be changed to one of the other spare fields, if
necessary.<P>
Versions of ACE from 4.3.3 and beyond destroy dynamically
allocated singletons in the ACE library. But, they may not
properly destroy some static objects. If you have trouble
running a program multiple times, it may be necessary to unload
the module, using unld, and reload it between runs.
Alternatively, you could try calling <code>cplusDtors</code> and
then <code>cplusCtors</code> between runs.<P>
<LI><B>MVS OpenEdition</B> <P>
All of ACE has been ported to OpenEdition by Chuck Gehr <<A
HREF="mailto:gehr@sweng.stortek.com">gehr@sweng.stortek.com</A>>.
The ACE library, all the tests and most of the examples and apps
build clean. There are still some problems that need to be
ironed out:<P>
MVS does not support the dynamic linking dl...() calls that the
Service Configurator uses to dynamically link services at run
time. As a result, all the examples and apps that use a svc.conf
file (for dynamically configuring service objects) do not work,
however, most of these apps can be built/run statically. Also,
the Svc_Conf_l.cpp and Svc_Conf_y.cpp files are generated using
flex and yacc on a ascii (not ebcdic) machine and as a result
they don't work very well with ebcdic svc.conf files. We should
be able to regenerate these files on MVS but MVS doesn't have
flex. This is something that needs to be done.<P>
Some of the tests do not execute properly. This is a minority
and over time the goal is to get to 100%.<P>
The make scheme for some of the apps still doesn't work
perfectly on MVS. This is mainly due to the way shared
libraries are handled on MVS. See <A HREF="#mvs">additional
build tips for MVS</A> for more on this.<P>
<li><strong>QNX Neutrino</strong><p>
ACE has been ported to <a

<li><strong>PharLap TNT Embedded ToolSuite (ETS)</strong><p>
ACE has been ported to <a
href="http://www.pharlap.com">PharLap's</a> TNT Embedded
ToolSuite (ETS) version 9.1. The port is being tested with
Microsoft Visual C++ 6.<p> To build for PharLap, use the
ace/config-pharlap.h configuration file, and the instructions
for building on Win32. Building the ACE library is the same as
for regular Win32 platforms, except you choose one of the PharLap
ETS configurations to build within Visual C++. Only static
library configurations are available for PharLap at this time.
For an example of how to build
binaries, see the tests directory. The tests_pharlap_msvc.lnk
file is a LinkLoc commands file that the ACE tests are built
with. It is likely that local sites may need to adjust this file
for their target environment. <p> If you have any fixes or

If you use the GNU GCC g++ compiler please note the following:
<UL>
<li>If you have problems building shared libraries with egcs 1.1 or 1.1.1
on SunOS 2.5 or 2.5.1 that look like this:
<pre>
/usr/ccs/lib/libgen.a(reg_compile.o): In function `_get_vars_storage':
reg_compile.o(.text+0x30): relocation truncated to fit: R_SPARC_GOT13 free
</pre>
the suggested workaround is to comment out the <code>ACE_HAS_REGEX</code>
<code>#define</code> in <code>ace/config-sunos5.5.h</code>.
Or better, create an <code>ace/config.h</code> that looks like:
<pre>
#ifndef ACE_CONFIG_H
// ACE_CONFIG_H is defined by the following #included header.
#include "ace/config-sunos5.5.h"
#undef ACE_HAS_REGEX
#endif /* ACE_CONFIG_H */
</pre>
We don't know what causes the link problem, though the
workaround solves it.<p>
<li>With g++ 2.8.0, an internal compiler error is raised when
trying to compile ACE_Map_Manager instantiations. One workaround
is to disable optimization. The easiest way to do that is:
<pre><code>% make optimize=0</code></pre>
Or, you can edit your include/makeinclude/platform_sunos5_g++.GNU,
and comment out the <code>OCFLAGS</code> line.<P>

use egcs 1.1.1 (on Solaris) and 1.1.2, and recommend those versions.<p>
<LI>Earlier (prior to 2.7.2) versions of g++ may not compile
certain parts of ACE correctly due to compiler bugs. Please
upgrade to g++ 2.7.2 or greater.<P>
<LI>Make sure to update your gcc <code>config.status</code>
file. This file is produced when installing gcc; it specifies
where to install the binary files that gcc uses. For example,
it specifies whether to use Solaris's <code>/usr/ccs/bin</code>
binary utils or GNU binary utils. The
<code>config.status</code> file is an output of the gcc
<code>configure</code> script; it is preferable to use the
<code>--prefix</code> option to <code>configure</code> instead
of hacking its output.<P>
<LI>If you are getting weird link errors when building libACE
on Solaris you are probably using the GNU linker. Try using the
Sun linker (/usr/ccs/bin/ld) instead. Note that gcc first looks
for the GNU linker if it is installed along with gcc. The only
way to not use the GNU linker is to delete it from the
installation or to build your own compiler with no linker. Be
aware that you still need the libraries and includes of gcc.<P>
NOTE: if you do use the GNU linker, you might need to change
the <code>-G</code> flag to <code>-shared</code> in
the <code>SOFLAGS</code> definition in your
<code>include/makeinclude/platform_macros.GNU</code>.<p>
<LI>Don't get too confused about contradictory statements in
the gcc documentation. It was written by different
people...<P>
<LI>Make sure that the linker invoked by gcc produces code
that initializes static objects. Please see gcc's
documentation for using <CODE>collect2</CODE>.<P>
<LI>By default, gcc (thru version 2.7.2, at least) uses
implicit template instantiation. Besides wasting space, this
breaks the use of ACE_Singleton: instead of one singleton
instance, there could be one instance per object (.o) file that
"sees" the template. Therefore, we have overridden this default
in ACE by enabling the -fno-implicit-templates option to CCFLAGS
in all include/makeinclude/platform_*.GNU files that set CXX to
g++.<P>
<LI>The disadvantage of this approach is that you must
add template specializations for all templates that your
application uses to your own code. (The ACE libraries are
self-contained: you don't need to add the templates that they
use internally.) Examples of template specializations occur in
quite a few ACE .cpp files; see the end of <A
HREF="apps/Gateway/Gateway/Connection_Handler.cpp">apps/Gateway/Gateway/Connection_Handler.cpp</A>
for one example. An easy way to figure out what template
instantiations are need is to try to build your executable and
pipe the output through c++filt. The linker will report the
missing instantiations as undefined symbols. Iteration may be
necessary, if the template instantiations themselves reference
other templates.<P>
<LI>Alternatively, you could use the <A NAME="repo">-frepo</A>
option available with
recent egcs versions (2.90 and later, I think) instead of
-fno-implicit-templates. (Patches for earlier g++ versions
might be available from
<a href="ftp://ftp.cygnus.com/pub/g++/">Cygnus</a>.)
ACE readily supports this option for
application code: to enable it just add <code>repo=1</code> to
your <code>make</code> invocation, or to your
<code>include/makeinclude/platform_macros.GNU</code>.<p>
The size of the ACE library is typically reduced by about
25 percent with repo=1, compared to the default with
-fno-implicit-templates. This savings results from not
instantiating unused classes, and from not instantiating
unused member functions of those template classes which are
instantiated.<p>
However, repo=1 requires care if your application creates libraries,
in order to avoid multiple instantiations. We avoid the problem
in ACE (and TAO) by including all of the ACE object files into
other ACE (and TAO) libraries. Please see the g++ FAQ and gcc
manual for more information on the -frepo option.<p>
Furthermore, it appears that g++ may have problems instantiating
all templates properly with -frepo. We have worked around these
problems (by using explicit instantiations even with ACE_HAS_GNU_REPO)
with egcs 1.1.2. A quick try with g++ 2.95 showed more problems,
so we don't support repo=1 with that g++ version, yet.<p>
<li>The implementation of templates for g++ version 2.8
eliminates the restriction against static data members in
template classes.<p>
<li>A final alternative is to
remove the <code>-fno-implicit-templates</code> option from the
CCFLAGS macro in your include/makeinclude/platform_macros.GNU,
and thereby use the default g++ implicit template
instantiation.<P>
<LI>Thanks to Thilo Kielmann <<A
HREF="mailto:kielmann@informatik.uni-siegen.de">kielmann@informatik.uni-siegen.de</A>>
for reporting the problem with ACE_Singleton on g++, and for
helping to find and implement these solutions.<P>
<LI>On VxWorks only, g++ (thru version 2.7.2, distributed
with Tornado 1.0.1/VxWorks 5.3.1), for x86 targets,
-fno-implicit-templates is broken. In addition, -O2
is not supported on some targets.<P>

<li>ACE transparently supports egcs, for the most part. Please see
<a href="#g++">Compiling ACE with g++</a> in this document. And,
please use the appropriate g++ config and platform files for the OS on
which you will use egcs.<p>
<li><strong><blink><font color="#ff0000">WARNING:</font></blink></strong>
The default behavior of the ACE Makefiles is to add
<code>-fno-exceptions</code> to egcs (and g++ starting with
version 2.8.0) invocations. This disables exception handling
support. On Solaris/sparc and Linux/alpha, it results in a 25
percent reduction in the size of libACE.so. To enable exception
handling, add <code>exceptions=1</code> to your
<code>make</code> command line invocation, or to your
<code>$ACE_ROOT/include/makeinclude/platform_macros.GNU</code>.<p>
<li>egcs may have trouble linking some executables, such as the ACE
IOStream_Test, if its static libraries are used. Though
<a href="mailto:trose@bridgewatersys.com">Tim Rose</a> reports
that egcs 1.1.1 static libraries work just fine on Solaris 2.6

and 105490-07.<p>
If you need or want to use egcs' shared libraries, build it
with the <code>--enable-shared</code> egcs config option. The
<code>--enable-shared</code> option is <strong>not</strong> an
egcs run-time option. Build egcs in a way similar to the
following example:
<pre><code>
$ ./configure --enable-shared
$ make bootstrap
</code></pre>
Be sure to set your <code>LD_LIBRARY_PATH</code> environment
variable, if necessary, to pick up those shared libraries.<p>
<li>On DEC Alpha, egcs through version 1.03a, at least, may fail
to build ACE if debugging (-g) is enabled. The fix is to
edit the egcs gcc/mips-file.c file, at line 976, and change
<code>PAGE_SIZE</code> to 8192. Then rebuild ACE. Thanks to

Thanks to <a href="mailto:ssweeney@sanders.com">Skye Sweeney</a> for trying it
out and <a href="mailto:othman@cs.wustl.edu">Ossama Othman</a> for discovering the
option with egcs.<p>
Heres a note on how to go about this (contributed by Skye
Sweeney):<p>
1) -fsquangle the name is a combination of squash and mangle!<p>
2) -fsquangle compresses the mangled names.<p>
3) All libraries must be compiles with the option. You cannot simply
compile modules that have large names with it. This includes system
libraries and vendor libraries like RogueWave.<p>
4) The "simple" solution is not to add the option to each makefile,
but rather recompile the compiler to have the option on by default.
This is done by editing the file `gcc/cp/decl2.c', setting
`flag_do_squangling = 1', then rebuilding the compiler and
libraries.<p>
5) After many false starts and linking snafus, I can recompile my
ACE/TAO/RogueWave/Lex/Yacc 100 Meg application.<p>

The following explains how to build ACE on <A HREF="#unix">UNIX</A>
and <A HREF="#win32">Win32</A>.
<h4>General Rules</h4>
<UL>
<li><p>Many features in ACE can be modified by defining some macros in
<code>$ACE_ROOT/ace/config.h</code>. These macros should
<em><b>always</b></em> appear <em><b>before</b></em> including
your platform specific config file.</p>
<li><p>However, if you want to undefine/redefine macros defined in the
platform specific config file, these <code>#undef</code> should
come <em><b>after</b></em> the config file.</p>
<LI> If you're planning to build ACE on multiple platforms, you may
want to consider <A HREF="#cloning">cloning the source tree</A>
before you start. <P>
</UL>
<hr align=left width="50%">
<H4><A NAME="unix">Building and Installing ACE on UNIX</A></H4>
Building and installing ACE on UNIX is relatively simple (the <A
HREF="#win32">process</A> for Win32 is different). Here's what you
need to do:<P>
<OL>
<LI>Install <A HREF="ftp://prep.ai.mit.edu/pub/gnu/make/">GNU make</A>
3.7 or greater on your system (available via
anonymous ftp from prep.ai.mit.edu in the pub/gnu/make/ directory).
You <EM>must</EM> use GNU make or ACE won't compile.<P>
<LI>Add an environment variable called ACE_ROOT that contains the
name of the root of the directory where you keep the ACE wrapper
source tree. The ACE recursive Makefile scheme needs this information.
There are several ways to set the ACE_ROOT variable. For
instance, in my .login file I have the following entry:<P>
<pre><code>
% setenv ACE_ROOT /home/cs/faculty/schmidt/ACE_wrappers
</code></pre><P>
However, if you're building a number of versions of ACE, e.g., for
different OS platforms or for different releases of ACE, you might use
the following approach:
<pre><code>
% setenv ACE_ROOT $cwd
</code></pre>
<LI>Edit the $ACE_ROOT/ace/OS.h file to update things like default
hostname and port numbers you'd like the programs in the
$ACE_ROOT/{apps,tests} directories to use by default. Note,
however that you can normally skip this step because the
defaults are typically fine for most systems. <P>
<LI>Create (via <code>ln -s</CODE> or <CODE>cp</CODE>) a
<code>$ACE_ROOT/ace/config.h</code>
file that contains the appropriate platform/compiler-specific
header configurations, e.g.,
<PRE><CODE>
% ln -s config-sunos5-sunc++-4.x.h config.h
</CODE></PRE>
This file
contains the #defines that are used throughout ACE to indicate
which features your system supports (see the
<code>$ACE_ROOT/ace/OS.h</code> file for many examples of how
the ACE build configuration is affected by these macro
settings). Make sure you settings are placed
<strong>before</strong> the inclusion of the platform-specific
header file.<P>
There are config files for most versions of UNIX. If there
isn't a version of this file that matches your
platform/compiler, you'll need to make one. Please send me
email if you get it working so I can add it to the master ACE
release.<P>
<LI>Create (via <code>ln -s</CODE> or <CODE>cp</CODE>) a
$ACE_ROOT/include/makeinclude/platform_macros.GNU file
that contains the appropriate platform/compiler-specific
Makefile configurations, e.g.,
<PRE><CODE>
% ln -s platform_sunos5_sunc++.GNU platform_macros.GNU
</CODE></PRE>
This file
contains the compiler and Makefile directives that are
platform/compiler-specific<P>
<LI>Note that because ACE builds shared libraries, you'll need to set
LD_LIBRARY_PATH to whereever you put the binary version of the
ACE library. For example, you probably want to do something
like the following<P>
<pre><code>
% setenv LD_LIBRARY_PATH $ACE_ROOT/ace:$LD_LIBRARY_PATH
</code></pre><P>
<LI>When all this is done, hopefully all you'll need to do is type:<P>
<pre><code>
% make
</code></pre><P>
at the root of the ACE source tree. This will build the ACE
library, tests, the examples, and the sample applications.
Building the entire ACE release can take a long time and consume
lots of disk space, however. Therefore, you might consider
cd'ing into the <A HREF="ace">$ACE_ROOT/ace/</a> directory and
running <CODE>make</CODE> there to build just the ACE library.
As a sanity check, you might also want to build and run the
automated <A HREF="tests/README">"one-button" tests</A> in <A
HREF="tests/">$ACE_ROOT/tests/</a>. Finally, if you're also
planning on building <A
HREF="http://www.cs.wustl.edu/~schmidt/TAO.html">TAO</A>, you
should build the <A
HREF="http://www.cs.wustl.edu/~schmidt/gperf.ps.gz">gperf</A>
perfect hash function generator application in <A
HREF="apps/gperf">$ACE_ROOT/apps/gperf/</A>.<P>
<LI>If you need to regenerate the Svc_Conf_y.cpp file, you'll need to
get <A HREF="http://www.cs.wustl.edu/~schmidt/byacc.tar.gz">Berkeley
YACC</A>. However, you should rarely, if ever, need to do this.<P>
</OL>
<P><hr align=left width="50%"><P>
<H4><A NAME="win32">Building and Installing ACE on Win32</A></H4>
First, if you are upgrading from an older release, clean up everything
and rebuild from scratch to ensure that everything is rebuilt
correctly. You might have to manually go through the ACE directories
and delete all *.obj, *.dll, *.lib, *.ilk, *.pdb, *.idb, *.ncb, *.opt,
and *.exp files in order to start over from scratch (the Clean command
in MSVC may not do this). <P>
ACE contains project files for Microsoft Visual C++ 5.0 or later
(*.dsw) and IBM's VisualAge C++ compiler (*.icc). There are also
Makefile.bor files to compile ACE, the ACE one-button tests, and TAO
with Borland C++ Builder. <P>
The Borland C++ Builder 4.0 port has been done by <A
HREF="mailto:jody@atdesk.com">Jody Hagins</A> and <A
HREF="mailto:chris@kohlhoff.com">Christopher Kohlhoff</A>. By
default, the ACE/TAO libraries built for Borland C++ Builder are
intended for use with generic console or windows applications and they
link against the corresponding C++ runtime library. Applications
created using BCB's RAD environment, such as ChatClient, must link
against the VCL-compatible (ie pascal-compatible) runtime library. To
tell the difference between these libraries the VCL-compatible ones
have a 'p' in the suffix (i.e., 'p' for pascal). To build VCL
compatible libraries try
<pre><code>
make -f Makefile.bor -DPASCAL
</code></pre>
Please see <A
HREF="http://www.tenermerx.com/tao_bcb/index.html">http://www.tenermerx.com/tao_bcb/index.html</A>
for more information on building ACE+TAO with Borland C++ Builder. <P>
<EM>Note concerning MSVC 5.0 and Service Pack 3:</EM> There has been
confusion regarding MSVC 5 and its Service Pack 3. Some ACE users
have, in the past, had problems with SP3 that were not present in SP2.
Thanks to the diligent efforts of <A
HREF="mailto:fultonb@pcnet1.ascs.aro.allied.com">Bill Fulton</A>, the
mystery appears to be solved. The key? (Oh, this is a good one...)
It would appear that there are actually multiple versions of SP3 in
existence. The earlier ones have the bug, while later ones have it
fixed. The service pack downloadable from Microsoft's web site as of
June 16, 1998 works fine. The CD containing SP3, if it has part
number X03-50158 on the disc (the part number on the jacket is
probably different), also works fine.
Note, however, that regardless of the version of SP3, there are some
STL bugs in SP3 which you should get corrected. Please see <A
HREF="http://www.dinkumware.com/vc_fixes.html">http://www.dinkumware.com/vc_fixes.html</A>
for details. Thank you to <A HREF="mailto:ben@jetpen.com">Ben Eng</A>
for the pointer to the STL fixes.<P>
Right now there is a SP4 (and hopefully only one of them) which fixes a
deadlock problem in the STL. <P>
We no longer actively support MSVC 4.x or earlier. ACE might work with
these compilers but probably not without a bit of effort. <P>
<OL>
<LI>Uncompress the ACE distribution into a directory, where it will create a
ACE_wrappers directory containing the distribution. The ACE_wrappers
directory will be referred to as ACE_ROOT in the following steps -- so
ACE_ROOT\ace would be C:\ACE_wrappers\ace if you uncompressed into the
root directory.<BR>
<BR>
<LI>Create a file called <code>config.h</code> in the ACE_ROOT\ace
directory that contains: <BR>
<BR>
<CODE>#include "ace/config-win32.h"</CODE><BR>
<BR>
<LI>Now load up the project file for ACE (ACE_ROOT\ace\ace.dsw). <BR>
<BR>
<LI>Each project will contain several different configurations. These
are a mixture of Debug/Release, MFC/Non-MFC, and Static/Dynamic
library versions for both i386 and sometimes Alpha machines.
Make sure you are building the one you'll use (for example, the
debug tests need the debug version of ACE, and so on). All these
different configurations are provided for your convenience. You
can either adopt the scheme to build your applications with
different configurations, or use <code>ace/config.h</code> to
tweak with the default settings on NT.<BR>
<STRONG>Note:</STRONG> If you
use the dynamic libraries, make sure you include ACE_ROOT\bin
in your PATH whenever you run programs that uses ACE. Otherwise
you may experience problems finding ace.dll or aced.dll.<BR>
<BR>
<LI>If you are building for Windows NT then you can start building
without anymore changes. If you are building on Windows 9x/Me,
then you should add the line <BR>
<BR>
<CODE>#define ACE_HAS_WINNT4 0</CODE><BR>
<BR>
before the #include statement in ACE_ROOT\ace\config.h and it
will turn off some Windows NT specific code in ACE.<BR>
<BR>
<li>If you want to use the standard C++ headers (iostream, cstdio, ...
as defined by the C++ Standard Draft 2) that comes with MSVC,
then add the line: <BR>
<BR>
<CODE>#define ACE_HAS_STANDARD_CPP_LIBRARY 1</CODE><BR>
<BR>
before the #include statement in ACE_ROOT\ace\config.h.<BR>
<br>
<li>To use ACE with MFC libraries, also add the following to
your <code>config.h</code> file. Notice that if you want to
spawn a new thread with CWinThread, make sure you spawn the
thread with THR_USE_AFX flag set.<br>
<br>
<code>#define ACE_HAS_MFC 1</code><br>
<br>
By default, all of the ACE projects use the DLL versions of the
MSVC run-time libraries. You can still choose use the static (LIB)
versions of ACE libraries regardless of run-time libraries. The
reason we chose to link only the dynamic run-time library is that
almost every NT box has these library installed and to save disk
space. If you prefer to link MFC as a static library into ACE, you
can do this by defining <code>ACE_USES_STATIC_MFC</code> in your
<code>config.h</code> file. However, if you would like to link
everything (including the MSVC run-time libraries) statically,
you'll need to modify the project files in ACE yourself.<p>
<li>Static version of ACE libraries are build with
<code>ACE_AS_STATIC_LIBS</code><br> defined. This macro should
also be used in application projects that link to static ACE
libraries<BR>
<BR>
Optionally you can also add the line <BR>
<BR>
<CODE>#define ACE_NO_INLINE</CODE><BR>
<BR>
before the #include statement in ACE_ROOT\ace\config.h to disable
inline function and reduce the size of static libraries (and your
executables.)<BR>
<BR>
<li>ACE DLL and LIB naming scheme:<br>
<br>
We use the following rules to name the DLL and LIB files in ACE
when using MSVC.<br>
<br>
"Library/DLL name" + (Is static library ? "s" :
"") + (Is Debugging enable ? "d" : "")
+ {".dll"|".lib"}<br>
<br>
<li><a href="http://www.torus-software.com/">Barry
Hoggard</a> maintains a <a
href="http://www.torus-software.com/corba/">CORBA Page</a>
which contains very helpful information on setting MSVC project
settings. You'll need to filter out stuff related to TAO if you
only use ACE.<br><br>
</Ol>
<B>ACE TESTS</B><P>
The tests are located in ACE_ROOT\tests. There is also a workspace in
that directory to build all the tests (tests.dsw)<P>
Once you build all the tests (Batch Build works well for this), you
can run perl script <code>run_test.pl</code> or the the batch file <a
href="tests/run_tests.bat"><code>run_tests.bat</code></a> in the
<code>tests</code> directory to try all the tests.<p>
<B> BUILDING ACE ON A WIN32 MACHINE THAT LACKS A NETWORK CARD </B><P>

<B>NT ALPHA CONFIGURATIONS</B>
<P>CUrrently some of the project files in ACE support Alpha configurations,
but they are somewhat out of date. Since the file list is global between i386
and Alpha, they have a good chance of working. If not, they might need to
be created as below.</P>
<P>Here are the steps we use to add an Alpha Configuration.</P>
<OL>
<LI>Load the project on the Alpha machine.
<LI>Go to the Build menu and then Configurations.

<LI>Prepend "Alpha " to the beginning of the name under
"Configuration".
<LI>Click OK.
<LI>Close the "Configurations" window.
<LI>Now go to the Project settings.
<LI>For the General Settings, change the output directories to standard ACE
output directores. Intermediate Directories are "Debug" and
"Release" in most cases. The Output Directories are blank,
except for Release versions of executables, in which it is also
"Release".
<LI>For the C/C++ Settings, make sure that the Code Generation's runtime
library is set to "Multithreaded DLL" or "Debug Multithreaded
DLL".
</OL>
<P><B>Note:</B> MSVC 6 has a bug where if a .dsp is converted from version 5 to 6 on
x86, the Alpha configuration can get corrupted. This seems to happen when additional
include or library directories are specified using backslashes instead of forward
slashes. If this occurs, the easiest way to fix it is to recreate it.</P>

For the most part, you should be able to follow the instructions above

applications that use it. Please see below for more information on
<a href="#VxWorks/NT">building ACE on NT hosts for VxWorks targets</a>.<P>
A few notes on VxWorks builds (thanks to
<a href="mailto:Paul_von_Behren@stortek.com">Paul von Behren</a>
for these notes):<p>
<UL>
<LI>VxWorks builds are done with a cross compiler, i.e., the compiles
are done on a workstation creating object modules which are
downloaded and loaded into the VxWorks target system.<p>
<LI>C++ object modules must be post-processed by a VxWorks
utility called "munch." ACE includes a perl script called
<A
HREF="bin/ace_ld">$ACE_ROOT/bin/ace_ld</A>,
which is called from the Makefiles, replacing
the traditional <code>ld</code> step. You must have perl installed
to use <code>ace_ld</code>. If perl is not on your path, you'll
have to set <code>PERL_PATH</code> to the full path (including
perl.exe), either in your
<code>$(ACE_ROOT)/include/makeinclude/platform_macros.GNU</code>
or in your environment.<P>
<LI>Wind River provides GCC/G++ cross-compilers for the
supported target platforms. The executables are named cc<target>
and g++<target>; for example, ccppc and g++cpp for PowerPC
targets.<p>
</UL>
You'll have to let ACE know the target type at compile time. There
are several ways to do this; please see the
<code>$ACE_ROOT/include/makeinclude/platform_vxworks5.x_g++.GNU</code>
platform file for detailed information.<P>
The VxWorks platform_vxworks*.GNU files are set up so that shared
libraries are not built on VxWorks, by default. Only static
libraries, with .a extension, are built. Therefore, it's not
necessary to set the LD_LIBRARY_PATH environment variable on your host
system when building for VxWorks targets. Please note, however, if
you use TAO on VxWorks that you will need to set your LD_LIBRARY_PATH
to find the TAO IDL compiler libraries (installed in the ace
directory) on the host.<P>
With g++, $ACE_ROOT/bin/ace_ld is used to munch object files and
libraries to set up calls to static constructors and destructors.
bin/ace_ld requires perl on the host platform.<P>
These non-default VxWorks kernel configuration <code>#defines</code>
are required with ACE:<P>
<pre>
#define INCLUDE_CPLUS /* include C++ support */
#define INCLUDE_CPLUS_IOSTREAMS /* include iostreams classes */
#define INCLUDE_POSIX_ALL /* include all available POSIX functions */
</pre>
For completeness, here are the non-default <code>#defines</code> that
we used for VxWorks 5.3.1/g++ 2.7.2:
<pre>
#define INCLUDE_CPLUS /* include C++ support */
#define INCLUDE_CPLUS_IOSTREAMS /* include iostreams classes */
#define INCLUDE_CONFIGURATION_5_2 /* pre-tornado tools */
#define INCLUDE_DEBUG /* pre-tornado debugging */
#define INCLUDE_LOADER /* object module loading */
#define INCLUDE_NET_SYM_TBL /* load symbol table from network */
#define INCLUDE_SYM_TBL_SYNC /* synchronize host and target symbol tables */
#define INCLUDE_NFS /* nfs package */
#define INCLUDE_PING /* ping() utility */
#define INCLUDE_POSIX_ALL /* include all available POSIX functions */
#define INCLUDE_RDB /* remote debugging package */
#define INCLUDE_RLOGIN /* remote login */
#define INCLUDE_RPC /* rpc package */
#define INCLUDE_SECURITY /* shell security for network access */
#define INCLUDE_SHELL /* interactive c-expression interpreter */
#define INCLUDE_SHOW_ROUTINES /* show routines for system facilities*/
#define INCLUDE_SPY /* spyLib for task monitoring */
#define INCLUDE_STARTUP_SCRIPT /* execute start-up script */
#define INCLUDE_STAT_SYM_TBL /* create user-readable error status */
#define INCLUDE_SYM_TBL /* symbol table package */
#define INCLUDE_UNLOADER /* object module unloading */
#define INCLUDE_WINDVIEW /* WindView command server */
</pre>
Also, automatic construction/destruction of static objects
should be enabled.<p>
If you use TAO, it's also a good idea to increase the
<code>NUM_FILES</code> parameter from its default of 50 to,
say, 1000.<p>
Please note that those VxWorks kernel configuration parameters
are set in the VxWorks configAll.h file. You must rebuild your
VxWorks kernel after modifying that file.<p>
If you're first getting started with ACE and/or VxWorks, I recommend
just building the ACE library and tests first. (Some of the ACE
examples, in System_V_IPC, don't build on VxWorks yet.) Then try
running the tests. Please see $ACE_ROOT/tests/README for the latest
status of the ACE tests on VxWorks.<P>
Please note that the <code>main</code> entry point is renamed to
<code>ace_main</code> (configurable via ACE_MAIN) on VxWorks with g++,
to comply with its restriction against using <code>main</code>.
In addition, ACE_HAS_NONSTATIC_OBJECT_MANAGER is enabled by default
to cleanly support construction and destruction of static objects.
Please see the <A HREF="#Non-static Object Manager">Non-static
ACE_Object_Manager</A> discussion for the important implication
of this feature.<p>
ACE threads (VxWorks tasks) can be named, for example, by supplying a
non-null argument to the Thread_Manager spawn routines. However,
names beginning with <code>"==ace_t=="</code> are forbidden because
that prefix is used internally by ACE.<p>
You can spawn a new task to run <code>ace_main</code>, using either
VxWorks <code>sp</code>, or ACE'S <A NAME="spa"><code>spa</code></A>.
<code>spa</code> can be used from the VxWorks shell to pass arguments
to <code>ace_main</code>. Its usage is:
<pre><code>
spa ace_main, "arg1" [, ...]
</code></pre>
All arguments must be quoted, even numbers.<p>
The ACE <a href="tests/">tests</a> write their output files in a
directory named <code>log/</code>, below the current
(<code>tests</code>) directory. If you don't have NFS included in
your VxWorks kernel, you can use these steps, provided by
<a href="mailto:clarence_m_weaver@md.northgrum.com">Clarence M. Weaver</a>,
to run the tests and capture their output:<p>
<ol>
<li>What I did was create a log directory on the boot NT host of my vxworks
target.<p>
<li>I copied all the test applications and the run_tests.vxworks script to
the parent of the log directory.<p>
<li>Using the target shell not the host shell, I "cd" to the directory
containing the script and test programs.<p>
<li>Invoked the script < run_tests.vxworks from this target shell.<p>
</ol>
<a href="mailto:Kirk.Davies@pobox.com">Kirk Davies</a> provided this
approach for running the ACE tests on Tornado II:
<ul>
<li>Under Tornado II, I set up the Target Server File System (TSFS), and
the test logs get written to the log subdirectory under that.<p>
<li>You have to set an environment variable before running the tests:
<pre>
putenv("ACE_TEST_DIR=/tgtsvr")
</pre><p>
</ul>
<h5><a name="VxWorks/SharedLibs">Building Shared Libraries for VxWorks</a>.</h5>
ACE supports shared libraries for VxWorks, but only with the g++
compiler. To build shared libraries instead of the default static
libraries, added <code>shared_libs=1</code> (<strong>not</strong>
<code>shared_libs_only=1</code>) to either your
<code>ACE_wrappers/include/makeinclude/platform_macros.GNU</code> or
your <code>make</code> invocation. Then, be sure to load the ACE (and
any other) shared library before loading your executable(s).<p>
A shared library for VxWorks uses the same code as for a static
(non-shared) library. However, calls to static constructors/
destructors are added. The code in the shared library <strong>must</strong>
be reentrant if you shared it between programs (tasks). The
ACE library meets this requirement.<p>
Shared libraries reduce build time, executable size, and load
time of the executable. But, you must manually load the shared
library before loading your executable(s) with a command such as:
<pre><code>
-> ld < libACE.so
</code></pre>
Shared libraries can be unloaded the same way an executable
(module) is unloaded.<p>
<strong>NOTE</strong>: Shared libraries on VxWorks aren't the same as
shared libraries on other operating systems. In particular, there is
no support for creating copies of writeable global (static) data in
the shared library. This includes the singleton ACE_Object_Manager
instance pointer. If you share global data between separate programs,
they may not work properly. See the discussion of shared code and
reentrancy in the VxWorks' <em>Programmers Guide</em>.<p>
Instead of trying to run separate programs onto a VxWorks target, we
recommend creating just one program, and spawning a thread for each
task. The TAO IDL_Cubit test <a
href="TAO/performance-tests/Cubit/TAO/IDL_Cubit/collocation_test.cpp">collocation
test</a> is a good example.<p>
<h5><a name="VxWorks/LinkToKernel">Linking ACE and/or TAO Libraries into the VxWorks Kernel</a>.</h5>
It's easy to link your ACE and/or TAO libraries into the VxWorks kernel.
Just build <a href="#VxWorks/SharedLibs">shared versions</a>, but
disable the munch step. The easiest way to do that is to set the
<code>LD</code> make variable to the name of your linker. For
example, to build a libACE.so for PowerPC that can be linked into
the kernel:
<pre>
% cd $ACE_ROOT/ace
% make LD=ldppc shared_libs=1
</pre>
After building the shared lib, link it into the kernel by setting
the <code>MACH_EXTRA</code> make variable in the kernel configuration
Makefile. Then, build the kernel using <code>make exe</code>.<p>
<h5><a name="VxWorks/NT">Building ACE on Tornado/NT hosts for VxWorks targets</a>.</h5>
The following, very useful information was contributed by
<a href="http://people.qualcomm.com/cryan">Chris Ryan</a>
and <a href="mailto:Paul_von_Behren@stortek.com">Paul von Behren</a>.
Please submit corrections, additions, or clarifications to the
the <a href="mailto:ace-users@cs.wustl.edu">ACE mailing list</a>.<p>
<strong>NOTE:</strong>The make (version 3.74) that is provided with
Tornado II cannot be used to build ACE. Use Cygnus' make (version 3.75)
instead.)<p>
<strong>NOTE:</strong>Optimization is enabled be default in
<a href=include/makeinclude/platform_vxworks5.x_g++.GNU>platform_vxworks5.x_g++.GNU</a>. However, the compiler that is shipped with Tornado II has
trouble compiling some files with -O2. To disable optimization
for an individual file, just add <code>optimize=0</code> to your
make invocation when compiling that file.<p>
Using the Cygnus tools, this approach works:
<ul>
<li>You'll build both your NT and VxWorks executables in the same
workspace (directory hierarchy). This works because the NT
compiler and ACE's Makefiles put their output in different
directories.<p>
<li>Set up your
<code>ACE_wrappers/include/makeinclude/platform_macros.GNU</code>
as usual for VxWorks. See
<a href="include/makeinclude/platform_vxworks5.x_g++.GNU">the
g++/VxWorks platform file</a> for more information.<p>
<li>Create an <code>ACE_wrappers/ace/config.h</code> file that looks
something like the following. tao_idl should be built to not support
native exception handling, because that's not available on VxWorks.
<pre>
#if defined (_MSC_VER) || defined (__BORLANDC__)
# include "ace/config-win32.h"
# undef ACE_HAS_EXCEPTIONS
#else
# include "ace/config-vxworks.h"
#endif
</pre><p>
<li>Set your <code>ACE_ROOT</code>, <code>CPP_LOCATION</code>,
<code>WIND_BASE</code>, and <code>WIND_HOST_TYPE</code> environment
variables.<p>
<li>Build for NT, then build for VxWorks.<p>
</ul>
A few additional Windows Notes, from Paul von Behren:<p>
<ul>
<li>Cygnus has created a Win32 API which is compatible with a
"generic" Unix environment. Using this library, they have ported a
large collection of GNU tools to WinNT/95 - including a port of
gcc/g++. See <A href="http://www.cygnus.com/misc/gnu-win32/">http://www.cygnus.com/misc/gnu-win32/</A>
A related link is <a href="ftp://ftp.cygnus.com/pub/gnu-win32/latest/">ftp://ftp.cygnus.com/pub/gnu-win32/latest/</a><p>
<li>To set up the command-prompt build environemnt, run
<code>Tornado\host\x86-win32\bin\TorVars.bat</code>. This is done
implicitly within the Tornado IDE.<p>
<li>To run <code>ace_ld</code>, you still need perl installed -
see <A href="http://www.activestate.com/software/default.htm">http://www.activestate.com/software/default.htm</A>
for Windows perl.<p>
<li>The Tornado IDE will use a standard Makefile for project
builds, but does not have a GUI interface for managing the
Makefile. By default, it will use rules from Makefile in the current
directory and you can configure it to add certain Makefile
targets to the project. If you have <code>ACE_ROOT</code> defined
before starting Tornado, you can specify an ACE Makefile as a Tornado
target and Tornado will then call make from the menu.<p>
</ul>
And Chris Ryan's instructions for building for VxWorks targets

Building and installing ACE Network Services on UNIX is relatively

Here's what you need to do:<P>
<OL>
<LI>Build and install ACE on UNIX as described <A
HREF="#unix">earlier</A>. If ACE is built at the root of the ACE
source tree (and ACE has been ported to your platform, of course) the
netsvcs static and shared object libraries should be built
automatically. In addition, the server driver program
(<CODE>main</CODE>) contained in <A

want to do something like the following<P>
<pre><code>

</code></pre><P>
<LI>By default, if the shared object library is built, the services
are linked into the <CODE>main</CODE> driver program dynamically.
To specify which services should be linked in and executed, edit the
<A
HREF="netsvcs/servers/svc.conf">$ACE_ROOT/netsvcs/servers/svc.conf</A>
file. During your editing, you should update information (such as the
default service port numbers) that affects the initialization of
services in this file. Refer to the
<A HREF="ACE-papers.html#config">Service Configurator</A>
documentation to learn how the configuration file is parsed and
how the services are dynamically linked and executed. In
addition, refer to the <A

Toshio Hori <toshi@etl.go.jp> provided these suggestions on building
just what's needed for (a subset of) TAO:<p>
I usually make:
<pre>
$ACE_ROOT/ace,
$ACE_ROOT/apps/gperf,
$TAO_ROOT/tao,
$TAO_ROOT/TAO_IDL, and
$TAO_ROOT/orbsvcs/orbsvcs
</pre>
and the whole make takes less than an hour on my Solaris 7 for intel,
Pentium-III/550MHz, 256MB memory, 512MB swap machine. (Top secret: I
renice the 'make' process to the highest priority, -20... ;-)
To save time and space, I set
<pre>
TAO_ORBSVCS = Naming Time Trader ImplRepo
</pre>
in $ACE_ROOT/include/makeinclude/platform_macros.GNU also. See
<a href="TAO/docs/configurations.html#orbsvcs">TAO's orbsvcs
library customization instructions</a> for more information.<p>
<HR><P>
<H3><A NAME="resource_requirements">System Resource Requirements</A></H3>
The amount of system resources required to build ACE and TAO varies
greatly. Platform, build options, and components built primarily
influence the required system resources. As a rough guide, the
typical peak memory requirement could be well over 256 Mb (notably,
for TAO's orbsvcs). An <strong>entire</strong> build of ACE and TAO
can use well over 1300 Mb of disk space. It's usually not necessary
to build <strong>all</strong> of ACE and TAO, though.<p>
Much less disk space is required for just the libraries. For example,
see the <a href="docs/ACE-subsets.html#ACE Library Size Breakdown">ACE
library subset sizes</a>.<p>
If you run out of memory when building, you might consider trying
some or all of these suggestions:<p>
<ul>
<li>Enable or increase virtual memory. If you're on a <a
href="#Linux">Linux</a> or <a href="#LynxOS">LynxOS</a> platform,
please see the appropriate sections above.<p>
<li>Disable/enable optimization and/or debugging. See the
<a href="#flags">Makefile Flags</a> discussion for information
on how to do that via ACE's Makefiles.<p>
<li>If you're using g++, try removing <code>-pipe</code> from
<code>CFLAGS</code> in your
<code>include/makeinclude/platform_macros.GNU</code> file.<p>
<li>Restrict the components that you build. For ACE and TAO, see the
discussion of <code>ACE_COMPONENTS</code> in the
<a href="docs/ACE-subsets.html">ACE subsets</a> page. For TAO's
orbsvcs, see the discussion of <code>TAO_ORBSVCS</code> in
<a href="TAO/docs/configurations.html#orbsvcs">orbsvcs Library configuration information</a>.<p>
If disk space is a problem, disabling debugging should greatly
reduce object code, and therefore, library size. This is especially
true with g++.<p>
Toshio Hori <toshi@etl.go.jp> provided these tips for reducing
disk space usage:<p>
To save space on a Unix machine, I usually run
'find . -name \*.dsw -o -name \*.dsp -o -name \*.bor | xargs rm -f'
in $ACE_ROOT at first after I untar the distribution. They are
meaningless in my environment (Files named '*.dsw' and '*.dsp' are
used for MSVC++ and files named '*.bor' are for Borland C++
Builder.)<p>
Finally, to save space, may want to run 'make clean' after 'make'. It
removes generated object files and leaves libraries/exectables
intact.<p>

<H4><A NAME="Non-static Object Manager">Non-static
ACE_Object_Manager</A></H4> The ACE_Object_Manager can be instantiated
as a static object, can be instantiated on the stack of the main
program thread, or can be explicitly instantiated and destroyed by the
application with <code>ACE::init ()</code> and <code>ACE::fini
()</code>. The comments in the <a href="ace/Object_Manager.h">header
file, <code>ace/Object_Manager.h</code></a> provide more detail.<P>
<strong><blink><font color="#ff0000">NOTE:</font></blink></strong>
Special requirements are imposed on applications if the
ACE_Object_Manager is instantiated, by ACE, on the stack of the main
thread. This behavior is selected by defining
<code>ACE_HAS_NONSTATIC_OBJECT_MANAGER</code> in
<code>ace/config.h</code>. Again, see the ACE Object_Manager <a
href="ace/Object_Manager.h">header file,
<code>ace/Object_Manager.h</code></a> for more information. One of
these requirements is discussed here, because it is so important.
Please note that <code>ACE_HAS_NONSTATIC_OBJECT_MANAGER</code> is
defined in the distributed ACE <code>config.h</code> headers for
VxWorks and Win32.<p>
The important requirement is that the program <strong>must</strong>
declare its <code>main</code> function with two arguments, even if
they're not used, and with <code>int</code> return type:
<pre><code>
int
main (int, char *[])
</code></pre>
If you don't declare <code>main</code> <strong>exactly</strong> that
way, then you'll see a link error about <code>ace_main_i</code> being
undefined.<p>
Alternatively, this feature can be disabled by commenting out the
#define ACE_HAS_NONSTATIC_OBJECT_MANAGER in the
<code>ace/config.h</code>. But, that will make repeated testing more
difficult on VxWorks. And, you'd either have to call static
constructors and destructors manually or unload/load the program
between runs. On Win32, disabling the feature can possibly lead to
shutdown difficulties.<p>
<strong><blink><font color="#ff0000">WARNING:</font></blink></strong>
<code>ACE_HAS_NONSTATIC_OBJECT_MANAGER</code> assumes that your
<code>main</code> function is named <code>main</code>. Any violation
of this assumption is at your peril. If you really need to call your
entry point something other than <code>main</code>, you'll need to
construct and destroy the ACE_Object_Manager. The best way to do that
is to call <code>ACE::init ()</code> and <code>ACE::fini ()</code>.
Or, see the <code>#define</code> of <code>main (int, char *[])</code>
in <a href="ace/OS.h"><code>ace/OS.h</code></a> to see how ACE does
that for entry points named <code>main</code>.

<H4><A NAME="cloning">Cloning the Source Tree</A></H4>
On UNIX platforms, we typically like to support multiple platform
builds using the same ACE source tree. This idiom is supported by ACE
using the $ACE_ROOT/bin/create_ace_build script or
$ACE_ROOT/bin/clone.cpp program.
To use build and use the clone program, first make sure there's a file
called platform_macros.GNU that contains the correct platform-specific
Makefile configurations in the $ACE_ROOT/include/makeinclude/
directory, as well as making sure there's a $ACE_ROOT/ace/config.h
file that includes the desired platform/compiler specific
configuration header. Then perform the following steps:<P>
<pre>
% cd $ACE_ROOT/bin
% make
% mv clone ~/bin
% rehash
</pre><P>
Then create a ./build subdirectory someplace, e.g., under $ACE_ROOT.
Once this is done, then invoke the top-level Makefile with the
"clone" target, e.g.:<P>
<pre>
% cd $ACE_ROOT
% mkdir build-SunOS5
% cd build-SunOS5
% make -f ../Makefile clone
% setenv ACE_ROOT $cwd
% make
</pre><P>
This will establish a complete tree of links. In addition, make sure
you set your LD_LIBRARY_PATH to $ACE_ROOT/ace:$LD_LIBRARY_PATH on SVR4
UNIX platforms.<P>
When you do a make in the $ACE_ROOT directory you will be producing
object code that is not stored in the same place as the original
source tree. This way, you can easily build another platform in a
parallel tree structure.<P>
<B> VERY IMPORTANT! </B><P>
If you use the "clone trick" discussed above, make sure that the
symbolic links are correctly in place before starting the build. In
particular, if you plan to clone the tree, it is preferable to do so
before you start a build procedure on the original tree. This is
because the build procedure create object directories (.obj and
.shobj) and the cloning procedure will clone these directories also.
You would end up with links pointing to object files of another
platform. If you clone the tree after you've done a build on the
original tree, make sure to remove all ".obj", ".shobj" and (any other
files or directories) in all subdirectories before starting the build
on your cloned tree.<P>
Alternatively, the perl script
<code>ACE_wrappers/bin/create_ace_build</code> can be used to create
build trees. It creates them below <code>ACE_wrappers/build</code>.
It filters out all but the necessary files, so the warning above does
not apply. See the comments at the top of the script itself for usage
information.

<H4><A NAME="corba">Building CORBA Versions of ACE</A></H4>
Note that if you are compiling with IONA's Orbix implementation of
CORBA or Visigenix's implementation of CORBA, you'll also need to set
ORBIX_ROOT to point to the root of the Orbix source tree and
ORBELINE_ROOT to point to the root of the ORBeline source tree. Since
many platforms don't have these CORBA tools the default for ACE does
*not* incorporate them. Thus, if you are compiling with Orbix or
ORBeline, make sure that you set up
$ACE_ROOT/include/makeinclude/platform_macros.GNU and
$ACE_ROOT/ace/config.h to use the config* and platform*
files that have "-orbix" in them!

<H4><A NAME="mvs">Additional Build Tips for MVS</A></H4>
For all intents and purpose, MVS OpenEdition (OE) is another flavor of
UNIX, therefore, the instructions under <A HREF="#aceinstall">Building
and Installing ACE on Unix</A> can be used along with the following
additional tips:<P>
You can get a copy of GNU make that has been ported to MVS OpenEdition from
the <A HREF="http://www.s390.ibm.com/products/oe/index.html">IBM OpenEdition web site</A>.
ACE's make scheme generates compile commands that have options and
operands interspersed. By default, the c89/cc/c++ compiler expects all options to
precede all operands. To get around this, you must set a special
compiler environment variable (_CXX_CCMODE) to 1 which tells the compiler
to allow options and operands to be interspersed.<P>
Note that the environment variable LD_LIBRARY_PATH is called LIBPATH
on MVS.<P>
Shared objects are built a little different on MVS than on
other UNIX implementations. This has been accounted for in the makefiles
that come with ACE When the linker (via the cxx command) builds the
libACE.so file it will also create a file called libACE.x. This is a
side-deck file and it must be included in subsequent link edits with
application code. For more information on this see the C/C++ MVS
Programming Guide. If you want to build your application statically,
i.e., using libACE.a instead of libACE.so, you can set ACELIB to
ACELIB_STATIC in platform_mvs.GNU.<P>
When the libACE.so file is built (via the MVS pre-linker and binder), you
will get a rc=4 from the pre-linker. This is ok. This is due to some
warnings about unresolved references which should get resolved during the
link step. Note, however, there shouldn't be any unresolved references
from the binder (linkage editor). You can get pre-link and link maps by
uncommenting the PMAP and LMAP lines in the platform_mvs.GNU file.
<P><hr align=left width="50%"><P>
<H4><A NAME="flags">Makefile Flags</A></H4>
GNU make provides many options to customize its operation. See its
documentation for more information. One example is that for multi-cpu
UNIX machines you will be able to build faster if you use:<P>
<pre><code>
% make -j <em>n</em>
</code></pre><p>
which allows parallel compilation. The number <i>n</i> should
typically be the number of CPUs. It is likely that builds will be
faster even on single-CPU UNIX machines with <code>make -j
2</code>.<P>
ACE further supports the following flags. They can be enabled either
on the command line, e.g., "make purify=1", or added to your
platform_macros.GNU. To disable the option, set the flag to null,
e.g., "make debug=". Some flags support setting to 0 disable, e.g.,
"make debug=0". debug=1 is enabled in the platform files that are
released with ACE.<P>
Please note that the effects of a flag may be platform specific.
Also, combinations of certain flags may or may not be allowed on
specific platforms, e.g., debug=1 opt=1 is supported by g++ but
not all other C++ compilers.<P>
If you use Purify or Quantify: purify or quantify <strong>must</strong>
be on your <code>PATH</code>. By default, ACE puts the Purify/Quantify
caches below <code>/tmp</code>. To override that, set the
<code>PURE_CACHE_BASE_DIR</code> variable, either in your environment
or on the <code>make</code> make command line, to the destination
directory for your instrumented libraries.<p>
<PRE>
