3# If these # comments don't work, trim them. Don't worry about any other
4# shell scripts, Configure will trim # comments from them for you.

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

11# Yes, you may rip this off to use in other distribution packages. This
12# script belongs to the public domain and cannot be copyrighted.
13#
14# (Note: this Configure script was generated automatically. Rather than
15# working with this copy of Configure, you may wish to get metaconfig.
16# The dist-3.0 package (which contains metaconfig) was posted in
dfe9444c
AD
17# comp.sources.misc and is available on CPAN under authors/id/RAM so
18# you may fetch it yourself from your nearest archive site.)

29SCO csh still thinks true is false. Write to SCO today and tell them that next
30year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31
32(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33we'd have to do is go in and swap the && and || tokens, wherever they are.)

2304df62 2063This installation shell script will examine your system and ask you questions
a0d0e21e 2064to determine how the perl5 package should be installed. If you get
2304df62
AD
2065stuck on a question, you may use a ! shell escape to start a subshell or
2066execute a command. Many of the questions will have default answers in square
2067brackets; typing carriage return will give you the default.
2068
2069On some of the questions which ask for file or directory names you are allowed
2070to use the ~name construct to specify the login directory belonging to "name",
2071even if you don't have a shell which knows about that. Questions where this is
2072allowed will be marked "(~name ok)".

2079
2080The prompter used in this script allows you to use shell variables and
2081backticks in your answers. You may use $1, $2, etc... to refer to the words
2082in the default answer, as if the default line was a set of arguments given to a
2083script shell. This means you may also use $* to repeat the whole default line,
2084so you do not have to re-type everything to add something to the default.
2085
2086Everytime there is a substitution, you will have to confirm. If there is an
2087error (e.g. an unmatched backtick), the default answer will remain unchanged
2088and you will be prompted again.
2089
2090If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2091the questions and use the computed defaults (or the previous answers if there
2092was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 2093You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 2094on the non-interactive behaviour for the remainder of the execution.

2103you'll have to generate a config.sh file by hand. Whatever problems you

2106This installation script affects things in two ways:
2107
21081) it may do direct variable substitutions on some of the files included
2109 in this kit.
21102) it builds a config.h file for inclusion in C programs. You may edit
2111 any of these files as the need arises after running this script.
2112
2113If you make a mistake on a question, there is no easy way to back up to it
2114currently. The easiest thing to do is to edit config.sh and rerun all the SH
2115files. Configure will offer to let you do this before it runs the SH files.

3543Since release 5.6, Perl has had two different threading implementations,
3544the newer interpreter-based version (ithreads) with one interpreter per
3545thread, and the older 5.005 version (5005threads).
3546The 5005threads version is effectively unmaintained and will probably be
3547removed in Perl 5.10, so there should be no need to build a Perl using it
3548unless needed for backwards compatibility with some existing 5.005threads
3549code.

3836 Your gcc has not been compiled for the exact release of

3838
3839 In general it is a good idea to keep gcc synchronized with
3840 the operating system because otherwise serious problems
3841 may ensue when trying to compile software, like Perl.
3842
3843 I'm trying to be optimistic here, though, and will continue.
