Bring Configure back into sync again with meta

[perl5.git] / Configure

#! /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 by the tool
# called "metaconfig". Rather than working with this copy of Configure,
# you may wish to get metaconfig. Perl uses a modified version of this
# tool, available in the "dist" folder in the checkout of the git repo
#    $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
# The original dist package (including metaconfig) is available via SVN:
#    $ svn co https://svn.code.sf.net/p/dist/code/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 using [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
         -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 : ignored for backward compatibility
  -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 ''

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.
