<H3>Building and Installing TAO</H3>
<!--#include virtual="/~schmidt/TAO-versions-i.html" --> If you can
help port TAO to other platforms we'd appreciate it. <P>
TAO can be obtained <A
HREF="http://www.cs.wustl.edu/~schmidt/TAO-obtain.html">electronically</A>
via the WWW and ftp. <A
HREF="http://www.cs.wustl.edu/~schmidt/ACE.html">ACE</A> is bundled
with the TAO release. You'll always need the most recent version of
ACE because TAO tracks changes to ACE very closely. <P>
<strong><blink><font color="#ff0000">WARNING:</font></blink></strong>
For users who have used ACE with other ORBs, linking TAO with a
version of ACE that is also linked against another ORB vendor's
library, <EM>e.g.</EM>, liborbix.so, will produce undefined and most
likely unpredictable and erroneous results. <P>
<HR><P>
<H3>On UNIX platforms</H3>
<OL>
<LI>Set <CODE>ACE_ROOT</CODE> environment variable as outlined in
the <a href="http://www.cs.wustl.edu/~schmidt/ACE_wrappers/ACE-INSTALL.html">ACE
installation notes</A>.<P>
<LI>Build and install ACE under <CODE>$ACE_ROOT</CODE>.<P>
<UL>
<LI>Change directory to <CODE>$ACE_ROOT/ace</CODE> and execute
<CODE><A HREF="#makenotes">make</A></CODE>.<P>
</UL>
<LI>Set <CODE>TAO_ROOT</CODE> environment variable to

<LI>Build and install the TAO release under <CODE>$TAO_ROOT</CODE>.<P>
<UL>
<LI>Change directory to <CODE>$TAO_ROOT/</CODE> and
execute <code><a href="#makenotes">make</a></code>.
This will build the TAO run-time library, the
TAO IDL compiler, the TAO CORBA Object Services,
the examples, and test programs. <P></li>
</UL>
<LI>To test that the TAO release is properly configured, follow
instructions on executing the various examples under
<CODE>$TAO_ROOT/tests</CODE>.<P>
</OL>
<h4><strong><a name="makenotes">A Note On Make</a></strong></h4>
Since TAO is built atop ACE, TAO re-uses ACE's Makefile structure as
well. Thus, just like ACE requires GNU Make, so too does TAO. More
exactly, versions of <code>make</code> which are known to <em>not</em>
work include those from Solaris 4.x and 5.x, HP-UX, the latest BSD,
etc.<p>
GNU Make can be obtained from various places in source form.<P>
<HR><P>
<h3>For Cross-Compiled Targets, such as VxWorks and LynxOS</h3>
If you are building TAO for a VxWorks target, please see the detailed
instructions for building and installing ACE and TAO in <a
href="http://www.cs.wustl.edu/~schmidt/ACE_wrappers/ACE-INSTALL.html#vxworks">$ACE_ROOT/ACE-INSTALL.html</a>.<p>
Cross-compiling TAO is not much different than building it for
self-host. The one major difference is that TAO's IDL compiler must
be built and run on the host; it's not necessary to run it on the
target. It's easiest to set this up by using a symlink (Unix) or copy
of <code>tao_idl</code> (NT). By way of example, here is how I setup
my Unix (SunOS5, using g++) workspace to support cross-compilation
(for VxWorks). It assumes that the ACE+TAO distribution has been
unpacked, with TAO below ACE_wrappers. It uses the
ACE_wrappers/bin/create_ace_build script to create a shadow build
tree:<p>
<ol>
<li><code>cd ACE_wrappers</code>
<li><code>bin/create_ace_build SunOS5_g++</code>
<li><code>bin/create_ace_build vxworks</code>
<li><code>cd build/vxworks/TAO</code>
<li><code>/bin/rm -r TAO_IDL</code>
<li><code>ln -s ../../SunOS5_g++/TAO/TAO_IDL</code>
</ol><p>
To build, first on the host, then on the target:<p>
<ol>
<li><code>cd build/SunOS5_g++</code>
<li><code>export ACE_ROOT=`pwd`;
export LD_LIBRARY_PATH=`pwd`/ace:$LD_LIBRARY_PATH</code>
<li><code>(cd ace; make && cd ../tests; make && cd ../TAO; make) >
make.log 2>&1</code>
<li><code>cd ../vxworks</code>
<li><code>export ACE_ROOT=`pwd`</code>
<li><code>(cd ace; make && cd ../tests; make && cd ../TAO; make) >
make.log 2>&1</code>
</ol><p>
For NT host, please see the detailed instructions for building and
installing ACE and TAO in <a
href="../ACE-INSTALL.html#vxworks">../ACE-INSTALL.html</a>.<p>
Please note that dynamic loading of libraries is not supported by TAO
for any cross-compiled target. Therefore, dynamic service
configuration of the TAO ORB is not supported.<p>
If using perfect hashing, TAO_IDL needs gperf to be built on the host.
That's the default on many platforms. First, build <code>gperf</code>
in the <code>ACE_wrappers/apps/gperf/src/</code> directory. Then, add
a symlink or copy to the <code>bin/</code> directory for the
target.<p>
<HR><P>
<H3>On Windows NT</H3>
<P><CODE>TAO_IDL</CODE> on NT will look for the Microsoft Visual C++
compiler as "C:\Program Files\DevStudio\VC\bin\CL.EXE". If this
compiler is located elsewhere (or if using a different compiler)
add a variable CPP_LOCATION to your environment and set it to the compiler
you want to use. This variable will override the default.
</P>
Remember to <a href="http://www.cs.wustl.edu/~schmidt/ACE_wrappers/ACE-INSTALL.html">set
up ACE</A> before building TAO.
<H4>Visual C++ 5.0/6.0</H4>
<P>It works best if TAO is placed in ACE_wrappers so TAO ends up in
<CODE>ACE_wrappers\TAO</CODE> because the Visual C++ 5 Project files
are set up to work in this configuration. If you move it, then make
sure you change the project files to look for the include and library
files in the correct place.</P>
<OL>
<LI>Make sure ACE is built (For Visual C++ 5.0/6.0, use ace.dsw). <P>
<LI>First make sure <CODE>ACE_wrappers\bin</CODE> is listed in the Executable
Directories in Tools|Options. This is needed if using the TAO_IDL
compiler under MSVC. If you intend to also use the release version of the
libraries, also add <CODE>ACE_wrappers\bin\Release</CODE> to the directories.
<STRONG>Note:</STRONG> The order that these are listed is important. If your
main development is with the debug versions, make sure \bin is before
\bin\Release, otherwise put the \bin\Release first. Because the output names
for the release and debug versions of TAO_IDL are the same, extra care must be
taken when both versions are generated simulataneously. <P>
<LI>Load the workspace <CODE>tao\TAO.dsw</CODE> and build the TAO
library. <P>
<LI>To build the Cubit test, load the workspace
<CODE>tests\Cubit\TAO\IDL_Cubit\IDL_Cubit.dsw</CODE> and build both
client and server. <P>
</OL>
<H4><A NAME="taoace">TAOACE.dsw</A></H4>
<P>TAOACE.dsw is a Visual C++ 5.0/6.0 workspace that loads the projects
ACE, TAO, TAO_IDL (the compiler), orbsvcs, gperf and the Naming Service.
The dependencies are set up to correctly between the projects so for
example, ACE will be built automatically when TAO is built. An easy
way to compile everything is to just compile the debug or release
version of the Naming Service.</P>
<H4>Visual C++ 4.x</H4>
<OL>
<LI>In Tools|Options, go to the Directories page and make sure that
include files paths includes ACE_wrappers\ and the root directory of
TAO (which can be <CODE>ACE_wrappers\TAO</CODE> if installed there).
The library files paths should include <CODE>ACE_wrappers\ace</CODE>.<P>
<LI>Load the project file <CODE>tao\TAO.mdp</CODE> and build the TAO
library.<P>
<LI>To build the Cubit test, load the project file
<CODE>tests\Cubit\TAO\test.mdp</CODE> and build both client and
server.<P>
</OL>
<H4>Changing Include Paths</H4>
<P>If you prefer <code>#include <corba.h></code> over <code> #include
<tao/corba.h></code> then you will need to change your Project Settings
to also contain the <code>TAO/tao</code> directory. You'll find this in the
C/C++ settings under Input.</P>
<H4>Creating Static Libraries (*.lib)</H4>
<P>TAO, orbsvcs, TAO_IDL, and the Simple Test all have extra project files
for static library builds. TAOACE_static.dsw contains all these projects,
and is set up much like <A HREF="#taoace">TAOACE.dsw</A>. To use the static
libraries in a project, make sure to the following settings are used in
the Project Settings.</P>
<UL>
<LI><strong>C/C++ | General:</strong> Add the Preprocessor Definitions
<CODE>TAO_HAS_DLL=0</CODE>, <CODE>ACE_HAS_DLL=0</CODE> and
<CODE>__ACE_INLINE__=0</CODE>
<LI><strong>C/C++ | Code Generation:</strong> Change Run-time
library to <CODE>Debug Multithreaded</CODE> (or
<CODE>Multithreaded</CODE> for Release)
<LI><strong>Link:</strong> Link with the static libs, such as
TAOs.lib or TAOsd.lib
</UL>
<HR>
<H3><A NAME="#VC">How to add IDL files into your Visual C++ projects</A></H3>
Point of contact: <A HREF="mailto:nanbor@cs.wustl.edu">Nanbor Wang</A>.
<P>Each IDL file generates .h, .i and .cpp files. Here is an example of
adding an IDL file named foobar.idl into a VC project.
<OL>
<LI>Create/open the workspace. Create server project and client project if
you haven't had them ready. Add the IDL file <foobar.idl> and other
non-IDL generated files into both client and server projects.</LI>
<LI>Added foobarC.h, foobarC.i, foobarC.cpp, foobarS.h, foobarS.i, and
foobarS.cpp into both server and client projects.</LI>
<LI>Now open the project setting window (Project -> Setting... or just
press Alt-F7.) Select the IDL files in both client and server projects.
Choose to set the setting for "All Configuration." Make sure the
"Always use custom build step" is checked and "Exclude from build" is
unchecked.</LI>
<LI>Click on the "Custom Build" tab. Add this entry as the build command
for IDL files:<BR><BR>
<PRE>tao_idl $(InputName).idl</PRE>
Notice that your absolute path to TAO_IDL may vary.</LI>
<LI>Now add the following entries as "Output file(s)."<BR><BR>
<PRE>
$(InputName)S.h
$(InputName)C.h
$(InputName)C.i
$(InputName)C.cpp
$(InputName)S.i
$(InputName)S.cpp
$(InputName)S_T.h
$(InputName)S_T.i
$(InputName)S_T.cpp
</PRE>
Add only one entry in each line.</LI>
<LI>You might also want to add the TAO_IDL compiler in as a dependency here
if you update TAO often. That way, if the compiler is changed, the
IDL files are recompiled automatically in the next build.</LI>
<LI>We are all set. Click OK.</LI>
<LI>Add foobarC.cpp and foobarS.cpp to both the client and server
project.</LI>
</OL>
<p>Notice that these procedures only setup the IDL compiler to perform
correctly. </p>
<P>P.S. If anyone knows how to set a default setting in VC so we don't
need to perform these procedures every time a new project gets set up,
please let us know. Thanks.
<P>
<HR>
<H3>Perl Scripts</H3>
<P>Several of TAO's tests and examples contain perl scripts that automate the
execution of these tests. The scripts are found as "run_test.pl" in the
directory of the test.</p>
<P> The versions of perl that we use are 5.005_02 on NT and 5.003 on Solaris.
The scripts may work on earlier versions of perl, but we cannot say for sure
that they do.</P>
<HR>
<H3>Native Exceptions</H3>
<P>TAO will use native exceptions if TAO_HAS_EXCEPTIONS is defined when it is
compiled. This can be accomplished in two ways: by defining ACE_HAS_EXCEPTIONS
in the config.h or config-*.h files (such as on Windows) or by using
<CODE>make exceptions=1</CODE> when you compile TAO.</P>
<P>Take note though, that this only enables support in ACE/TAO, the correct
compiler flags must also be given to the compiler to enable them.</P>
<HR>
