# (If you are trying to port this package to a machine without sh,
# I would suggest you have a look at the prototypical config_h.SH file
# and edit it to reflect your system. Some packages may include samples
# of config.h for certain machines, so you might look for one of those.)

# Yes, you may rip this off to use in other distribution packages. This

# (Note: this Configure script was generated automatically. Rather than
# working with this copy of Configure, you may wish to get metaconfig.
# The dist-3.0 package (which contains metaconfig) was posted in
# comp.sources.misc and is available on CPAN under authors/id/RAM so
# you may fetch it yourself from your nearest archive site.)

ARGGGHHHH!!!!!
SCO csh still thinks true is false. Write to SCO today and tell them that next
year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
we'd have to do is go in and swap the && and || tokens, wherever they are.)
[End of diatribe. We now return you to your regularly scheduled programming...]

OOPS! You naughty creature! You didn't run Configure with sh!

cat <<EOH
This installation shell script will examine your system and ask you questions
to determine how the perl5 package should be installed. If you get
stuck on a question, you may use a ! shell escape to start a subshell or
execute a command. Many of the questions will have default answers in square
brackets; typing carriage return will give you the default.
On some of the questions which ask for file or directory names you are allowed
to use the ~name construct to specify the login directory belonging to "name",
even if you don't have a shell which knows about that. Questions where this is
allowed will be marked "(~name ok)".
EOH
rp=''
dflt='Type carriage return to continue'
. ./myread
cat <<'EOH'
The prompter used in this script allows you to use shell variables and
backticks in your answers. You may use $1, $2, etc... to refer to the words
in the default answer, as if the default line was a set of arguments given to a
script shell. This means you may also use $* to repeat the whole default line,
so you do not have to re-type everything to add something to the default.
Everytime there is a substitution, you will have to confirm. If there is an
error (e.g. an unmatched backtick), the default answer will remain unchanged
and you will be prompted again.
If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
the questions and use the computed defaults (or the previous answers if there
was already a config.sh file). Type 'Configure -h' for a list of options.
You may also start interactively and then answer '& -d' at any prompt to turn
on the non-interactive behaviour for the remainder of the execution.
EOH
. ./myread
cat <<EOH
Much effort has been expended to ensure that this shell script will run on any
Unix system. If despite that it blows up on yours, your best bet is to edit
Configure and run it again. If you can't run Configure for some reason,
you'll have to generate a config.sh file by hand. Whatever problems you
have, let me (perlbug@perl.com) know how I blew it.
This installation script affects things in two ways:
1) it may do direct variable substitutions on some of the files included
in this kit.
2) it builds a config.h file for inclusion in C programs. You may edit
any of these files as the need arises after running this script.
If you make a mistake on a question, there is no easy way to back up to it
currently. The easiest thing to do is to edit config.sh and rerun all the SH
files. Configure will offer to let you do this before it runs the SH files.

On some older systems the default C compiler will not resolve multiple global
references that happen to have the same name. On some such systems the "Mcc"
command may be used to force these to be resolved. On other systems a "cc -M"
command is required. (Note that the -M flag on other systems indicates a
memory model to use!) If you have the Gnu C compiler, you might wish to use

*** WHOA THERE!!! ***
Your gcc has not been compiled for the exact release of
your operating system ($gccosandvers versus $osname$osvers).
In general it is a good idea to keep gcc synchronized with
the operating system because otherwise serious problems
may ensue when trying to compile software, like Perl.
I'm trying to be optimistic here, though, and will continue.
If later during the configuration and build icky compilation
problems appear (headerfile conflicts being the most common
manifestation), I suggest reinstalling the gcc to match
your operating system release.

In order to ease the process of upgrading, this version of perl
can be configured to use modules built and installed with earlier
versions of perl that were installed under $prefix. Specify here
the list of earlier versions that this version of perl should check.
If Configure detected no earlier versions of perl installed under
$prefix, then the list will be empty. Answer 'none' to tell perl
to not search earlier versions.
The default should almost always be sensible, so if you're not sure,
just accept the default.

I can use $nm to extract the symbols from your C libraries. This
is a time consuming task which may generate huge output on the disk (up
to 3 megabytes) but that should make the symbols extraction faster. The
alternative is to skip the 'nm' extraction part and to compile a small
test program instead to determine whether each symbol is present. If
you have a fast C compiler and/or if your 'nm' output cannot be parsed,
this may be the best solution.
You probably shouldn't let me use 'nm' if you are using the GNU C Library.

The perl executable is normally obtained by linking perlmain.c with
libperl${_a}, any static extensions (usually just DynaLoader), and
any other libraries needed on this system (such as -lm, etc.). Since
your system supports dynamic loading, it is probably possible to build
a shared libperl.$so. If you will have more than one executable linked
to libperl.$so, this will significantly reduce the size of each
executable, but it may have a noticeable affect on performance. The
default is probably sensible for your system.

I need to select a good name for the shared libperl. If your system uses
library names with major and minor numbers, then you might want something
like $majmin. Alternatively, if your system uses a single version
number for shared libraries, then you might want to use $majonly.
Or, your system might be quite happy with a simple libperl.$so.
Since the shared libperl will get installed into a version-specific
architecture-dependent directory, the version number of the shared perl
library probably isn't important, so the default should be o.k.
