#! /bin/sh
#
# If these # comments don't work, trim them. Don't worry about any other
# shell scripts, Configure will trim # comments from them for you.
#
# (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
# script belongs to the public domain and cannot be copyrighted.
#
# Note: this Configure script was generated automatically. Rather than
# working with this copy of Configure, you may wish to get metaconfig.
# The dist package (which contains metaconfig) is available via SVN:
# svn co https://svn.sourceforge.net/svnroot/dist/trunk/dist
#
# Though this script was generated by metaconfig from metaunits, it is
# OK to send patches against Configure itself. It's up to the Configure
# pumpkin to backport the patch to the metaunits if it is accepted.
# For more information on patching Configure, see pod/perlhack.pod
#
# The metaunits are also available from the public git repository:
# http://perl5.git.perl.org/metaconfig.git/ or
# $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
#
# See Porting/pumpkin.pod for more information on metaconfig.
#
# Generated on Sun Apr 1 12:00:35 CEST 2012 [metaconfig 3.5 PL0]
# (with additional metaconfig patches by perlbug@perl.org)

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!
I will attempt to remedy the situation by running sh for you...

Usage: $me [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
[-U symbol] [-U symbol=] [-A command:symbol...]
-d : use defaults for all answers.
-e : go on without questioning past the production of config.sh.
-f : specify an alternate default configuration file.
-h : print this help message and exit (with an error status).
-r : reuse C symbols value if possible (skips costly nm extraction).
-s : silent mode, only echoes questions and essential information.
-D : define symbol to have some value:
-D symbol symbol gets the value 'define'
-D symbol=value symbol gets the value 'value'
common used examples (see INSTALL for more info):
-Duse64bitint use 64bit integers
-Duse64bitall use 64bit integers and pointers
-Dusethreads use thread support
-Dinc_version_list=none do not include older perl trees in @INC
-DEBUGGING=none DEBUGGING options
-Dcc=gcc choose your compiler
-Dcc_as_ld use cc as ld
-Dprefix=/opt/perl5 choose your destination
-E : stop at the end of questions, after having produced config.sh.
-K : do not use unless you know what you are doing.
-O : let -D and -U override definitions from loaded configuration file.
-S : perform variable substitutions on all .SH files (can mix with -f)
-U : undefine symbol:
-U symbol symbol gets the value 'undef'
-U symbol= symbol gets completely empty
e.g.: -Uversiononly
-A : manipulate symbol after the platform specific hints have been applied:
-A append:symbol=value append value to symbol
-A symbol=value like append:, but with a separating space
-A define:symbol=value define symbol to have value
-A clear:symbol define symbol to be ''
-A define:symbol define symbol to be 'define'
-A eval:symbol=value define symbol to be eval of value
-A prepend:symbol=value prepend value to symbol
-A undef:symbol define symbol to be 'undef'
-A undef:symbol= define symbol to be ''
e.g.: -A prepend:libswanted='cl pthread '
-A ccflags=-DSOME_MACRO
-V : print version number and exit (with a zero status).

This is an UNSTABLE DEVELOPMENT release.
The version of this $package distribution is $xversion, that is, odd,
(as opposed to even) and that signifies a development release.
If you want a maintenance release, you want an even-numbered version.
Do ***NOT*** install this into production use.
Data corruption and crashes are possible.
It is most seriously suggested that you do not continue any further
unless you want to help in developing and debugging Perl.
If you *still* want to build perl, you can answer 'y' now,

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.
Every time 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.org) 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.

You may give one or more space-separated answers, or "none" if appropriate.
If you have a handcrafted Policy.sh file or a Policy.sh file generated by a
previous run of Configure, you may specify it as well as or instead of
OS-specific hints. If hints are provided for your OS, you should use them:
although Perl can probably be built without hints on many platforms, using
hints often improve performance and may enable features that Configure can't
set up on its own. If there are no hints that match your OS, specify "none";
DO NOT give a wrong version or a wrong OS.

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.

may find it convenient to place all vendor-supplied files in this

ease upgrades between binary-compatible maintenance versions of perl.
Of course you may also use these directories in whatever way you see
fit. For example, you might use them to access modules shared over a
company-wide network.
The default answer should be fine for most people.

this may be the best solution.

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 effect on performance. The

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.

In the following, larger digits indicate more significance. A big-endian
machine like a Pyramid or a Motorola 680?0 chip will come out to 4321. A
little-endian machine like a Vax or an Intel 80?86 chip would be 1234. Other
machines may have weird orders like 3412. A Cray will report 87654321,
an Alpha will report 12345678. If the test program works the default is
probably right.
