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.
5#
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.)
10#
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 1782This installation shell script will examine your system and ask you questions
a0d0e21e 1783to determine how the perl5 package should be installed. If you get
2304df62
AD
1784stuck on a question, you may use a ! shell escape to start a subshell or
1785execute a command. Many of the questions will have default answers in square
1786brackets; typing carriage return will give you the default.
1787
1788On some of the questions which ask for file or directory names you are allowed
1789to use the ~name construct to specify the login directory belonging to "name",
1790even if you don't have a shell which knows about that. Questions where this is
1791allowed will be marked "(~name ok)".

1796 . ./myread
1797 cat <<'EOH'
1798
1799The prompter used in this script allows you to use shell variables and
1800backticks in your answers. You may use $1, $2, etc... to refer to the words
1801in the default answer, as if the default line was a set of arguments given to a
1802script shell. This means you may also use $* to repeat the whole default line,
1803so you do not have to re-type everything to add something to the default.
1804
1805Everytime there is a substitution, you will have to confirm. If there is an
1806error (e.g. an unmatched backtick), the default answer will remain unchanged
1807and you will be prompted again.
1808
1809If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1810the questions and use the computed defaults (or the previous answers if there
1811was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1812You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1813on the non-interactive behaviour for the remainder of the execution.

1819Much effort has been expended to ensure that this shell script will run on any
1820Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1821Configure and run it again. If you can't run Configure for some reason,
1822you'll have to generate a config.sh file by hand. Whatever problems you

1825This installation script affects things in two ways:
1826
18271) it may do direct variable substitutions on some of the files included
1828 in this kit.
18292) it builds a config.h file for inclusion in C programs. You may edit
1830 any of these files as the need arises after running this script.
1831
1832If you make a mistake on a question, there is no easy way to back up to it
1833currently. The easiest thing to do is to edit config.sh and rerun all the SH
1834files. Configure will offer to let you do this before it runs the SH files.

3203 Your gcc has not been compiled for the exact release of
3204 your operating system ($gccosandvers versus $osname$osvers).
3205
3206 In general it is a good idea to keep gcc synchronized with
3207 the operating system because otherwise serious problems
3208 may ensue when trying to compile software, like Perl.
3209
3210 I'm trying to be optimistic here, though, and will continue.
3211 If later during the configuration and build icky compilation
