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.

613d6c3e 14# Note: this Configure script was generated automatically. Rather than
2304df62 15# working with this copy of Configure, you may wish to get metaconfig.

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

37SCO csh still thinks true is false. Write to SCO today and tell them that next
38year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

40(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
41we'd have to do is go in and swap the && and || tokens, wherever they are.)

2304df62 2245This installation shell script will examine your system and ask you questions
a0d0e21e 2246to determine how the perl5 package should be installed. If you get
2304df62
AD
2247stuck on a question, you may use a ! shell escape to start a subshell or
2248execute a command. Many of the questions will have default answers in square
2249brackets; typing carriage return will give you the default.
2250
2251On some of the questions which ask for file or directory names you are allowed
2252to use the ~name construct to specify the login directory belonging to "name",
2253even if you don't have a shell which knows about that. Questions where this is
2254allowed will be marked "(~name ok)".

2259 . ./myread
2260 cat <<'EOH'
2261
2262The prompter used in this script allows you to use shell variables and
2263backticks in your answers. You may use $1, $2, etc... to refer to the words
2264in the default answer, as if the default line was a set of arguments given to a
2265script shell. This means you may also use $* to repeat the whole default line,
2266so you do not have to re-type everything to add something to the default.
2267
cd95ead5 2268Every time there is a substitution, you will have to confirm. If there is an
2304df62
AD
2269error (e.g. an unmatched backtick), the default answer will remain unchanged
2270and you will be prompted again.
2271
2272If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2273the questions and use the computed defaults (or the previous answers if there
2274was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 2275You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 2276on the non-interactive behaviour for the remainder of the execution.

2282Much effort has been expended to ensure that this shell script will run on any
2283Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
2284Configure and run it again. If you can't run Configure for some reason,
2285you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 2286have, let me (perlbug@perl.org) know how I blew it.
2304df62

2287
2288This installation script affects things in two ways:
2289
22901) it may do direct variable substitutions on some of the files included
2291 in this kit.
22922) it builds a config.h file for inclusion in C programs. You may edit
2293 any of these files as the need arises after running this script.
2294
2295If you make a mistake on a question, there is no easy way to back up to it
2296currently. The easiest thing to do is to edit config.sh and rerun all the SH
2297files. Configure will offer to let you do this before it runs the SH files.

3508If you have a handcrafted Policy.sh file or a Policy.sh file generated by a
3509previous run of Configure, you may specify it as well as or instead of
3510OS-specific hints. If hints are provided for your OS, you should use them:
3511although Perl can probably be built without hints on many platforms, using
3512hints often improve performance and may enable features that Configure can't
3513set up on its own. If there are no hints that match your OS, specify "none";
3514DO NOT give a wrong version or a wrong OS.
