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.

16# The dist package (which contains metaconfig) is available via SVN:

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.

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 2229This installation shell script will examine your system and ask you questions
a0d0e21e 2230to determine how the perl5 package should be installed. If you get
2304df62
AD
2231stuck on a question, you may use a ! shell escape to start a subshell or
2232execute a command. Many of the questions will have default answers in square
2233brackets; typing carriage return will give you the default.
2234
2235On some of the questions which ask for file or directory names you are allowed
2236to use the ~name construct to specify the login directory belonging to "name",
2237even if you don't have a shell which knows about that. Questions where this is
2238allowed will be marked "(~name ok)".

2242 dflt='Type carriage return to continue'
2243 . ./myread
2244 cat <<'EOH'
2245
2246The prompter used in this script allows you to use shell variables and
2247backticks in your answers. You may use $1, $2, etc... to refer to the words
2248in the default answer, as if the default line was a set of arguments given to a
2249script shell. This means you may also use $* to repeat the whole default line,
2250so you do not have to re-type everything to add something to the default.
2251
2252Everytime there is a substitution, you will have to confirm. If there is an
2253error (e.g. an unmatched backtick), the default answer will remain unchanged
2254and you will be prompted again.
2255
2256If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2257the questions and use the computed defaults (or the previous answers if there
2258was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 2259You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 2260on the non-interactive behaviour for the remainder of the execution.

2266Much effort has been expended to ensure that this shell script will run on any
2267Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
2268Configure and run it again. If you can't run Configure for some reason,
2269you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 2270have, let me (perlbug@perl.org) know how I blew it.

2272This installation script affects things in two ways:
2273
22741) it may do direct variable substitutions on some of the files included
2275 in this kit.
22762) it builds a config.h file for inclusion in C programs. You may edit
2277 any of these files as the need arises after running this script.
2278
2279If you make a mistake on a question, there is no easy way to back up to it
2280currently. The easiest thing to do is to edit config.sh and rerun all the SH
2281files. Configure will offer to let you do this before it runs the SH files.

3491If you have a handcrafted Policy.sh file or a Policy.sh file generated by a
3492previous run of Configure, you may specify it as well as or instead of
3493OS-specific hints. If hints are provided for your OS, you should use them:
3494although Perl can probably be built without hints on many platforms, using
3495hints often improve performance and may enable features that Configure can't
3496set up on its own. If there are no hints that match your OS, specify "none";
3497DO NOT give a wrong version or a wrong OS.
