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

14# Note: this Configure script was generated automatically by the tool
15# called "metaconfig". Rather than working with this copy of Configure,
16# you may wish to get metaconfig. Perl uses a modified version of this
17# tool, available in the "dist" folder in the checkout of the git repo
18# $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
19# The original dist package (including metaconfig) is available via SVN:
20# $ svn co https://svn.code.sf.net/p/dist/code/trunk/dist

22# Though this script was generated by metaconfig from metaunits, it is
23# OK to send patches against Configure itself. It's up to the Configure
24# pumpkin to backport the patch to the metaunits if it is accepted.

39SCO csh still thinks true is false. Write to SCO today and tell them that next
40year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

42(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
43we'd have to do is go in and swap the && and || tokens, wherever they are.)

2304df62 2355This installation shell script will examine your system and ask you questions
a0d0e21e 2356to determine how the perl5 package should be installed. If you get
2304df62
AD
2357stuck on a question, you may use a ! shell escape to start a subshell or
2358execute a command. Many of the questions will have default answers in square
2359brackets; typing carriage return will give you the default.
2360
2361On some of the questions which ask for file or directory names you are allowed
2362to use the ~name construct to specify the login directory belonging to "name",
2363even if you don't have a shell which knows about that. Questions where this is
2364allowed will be marked "(~name ok)".

2369 . ./myread
2370 cat <<'EOH'
2371
2372The prompter used in this script allows you to use shell variables and
2373backticks in your answers. You may use $1, $2, etc... to refer to the words
2374in the default answer, as if the default line was a set of arguments given to a
2375script shell. This means you may also use $* to repeat the whole default line,
2376so you do not have to re-type everything to add something to the default.
2377
cd95ead5 2378Every time there is a substitution, you will have to confirm. If there is an
2304df62
AD
2379error (e.g. an unmatched backtick), the default answer will remain unchanged
2380and you will be prompted again.
2381
2382If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2383the questions and use the computed defaults (or the previous answers if there
2384was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 2385You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 2386on the non-interactive behaviour for the remainder of the execution.

2392Much effort has been expended to ensure that this shell script will run on any
2393Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
2394Configure and run it again. If you can't run Configure for some reason,
2395you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 2396have, let me (perlbug@perl.org) know how I blew it.

2398This installation script affects things in two ways:
2399
24001) it may do direct variable substitutions on some of the files included
2401 in this kit.
24022) it builds a config.h file for inclusion in C programs. You may edit
2403 any of these files as the need arises after running this script.
2404
2405If you make a mistake on a question, there is no easy way to back up to it
2406currently. The easiest thing to do is to edit config.sh and rerun all the SH
2407files. Configure will offer to let you do this before it runs the SH files.

3745If you have a handcrafted Policy.sh file or a Policy.sh file generated by a
3746previous run of Configure, you may specify it as well as or instead of
3747OS-specific hints. If hints are provided for your OS, you should use them:
3748although Perl can probably be built without hints on many platforms, using
3749hints often improve performance and may enable features that Configure can't
3750set up on its own. If there are no hints that match your OS, specify "none";
3751DO NOT give a wrong version or a wrong OS.
