# (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 so you may fetch it yourself from your nearest
# archive site. Check with Archie if you don't know where that can be.)

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...]

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 behavior 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 (chip@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.

In 5.001, Perl stored architecture-dependent library files in a directory
with a name such as $privlib/$archname,
and this directory contained files from the standard extensions and
files from any additional extensions you might have added. Starting
with version 5.002, all the architecture-dependent standard extensions
will go into a version-specific directory such as
$archlib,

$sitearch.

Some versions of Unix support shared libraries, which make executables smaller
but make load time slightly longer.
On some systems, mostly System V Release 3's, the shared library is included
by putting the option "-lc_s" as the last thing on the cc command line when
linking. Other systems use shared libraries by default. There may be other
libraries needed to compile $package on your machine as well. If your system

Your C linker may need flags. For this question you should
include -L/whatever and any other flags used by the C linker, but you
should NOT include libraries like -lwhatever.
Make sure you include the appropriate -L/path flags if your C linker
does not normally search all of the directories you specified above,

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 shouldn't let me use 'nm' if you have the GNU C Library.

The perl executable is normally obtained by linking perlmain.c with
libperl${lib_ext}, any static extensions (usually just DynaLoader), and
any other libraries needed on this system (such as -lm, etc.). Since
your system supports dynamic loading, it is probably possible to build
a shared libperl.$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

Previous version of $package used the standard IO mechanisms as defined in
<stdio.h>. Versions 5.003_02 and later of perl allow alternate IO
mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still
the default and is the only supported mechanism. This abstraction
layer can use AT&T's sfio (if you already have sfio installed) or
fall back on standard IO. This PerlIO abstraction layer is
experimental and may cause problems with some extension modules.
If this doesn't make any sense to you, just accept the default 'n'.
