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.)

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#
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.

20# Though this script was generated by metaconfig, it is OK to send
21# patches against it. It's up to the Configure pumpkin to backport
22# the patch to the metaunits if it is accepted.
23# See Porting/pumpkin.pod for more information on metaconfig.

34SCO csh still thinks true is false. Write to SCO today and tell them that next
35year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
36
37(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
38we'd have to do is go in and swap the && and || tokens, wherever they are.)

2304df62 2221This installation shell script will examine your system and ask you questions
a0d0e21e 2222to determine how the perl5 package should be installed. If you get
2304df62
AD
2223stuck on a question, you may use a ! shell escape to start a subshell or
2224execute a command. Many of the questions will have default answers in square
2225brackets; typing carriage return will give you the default.
2226
2227On some of the questions which ask for file or directory names you are allowed
2228to use the ~name construct to specify the login directory belonging to "name",
2229even if you don't have a shell which knows about that. Questions where this is
2230allowed will be marked "(~name ok)".
2231
2232EOH
2233 rp=''
2234 dflt='Type carriage return to continue'
2235 . ./myread
2236 cat <<'EOH'
2237
2238The prompter used in this script allows you to use shell variables and
2239backticks in your answers. You may use $1, $2, etc... to refer to the words
2240in the default answer, as if the default line was a set of arguments given to a
2241script shell. This means you may also use $* to repeat the whole default line,
2242so you do not have to re-type everything to add something to the default.
2243
2244Everytime there is a substitution, you will have to confirm. If there is an
2245error (e.g. an unmatched backtick), the default answer will remain unchanged
2246and you will be prompted again.
2247
2248If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2249the questions and use the computed defaults (or the previous answers if there
2250was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 2251You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 2252on the non-interactive behaviour for the remainder of the execution.

2258Much effort has been expended to ensure that this shell script will run on any
2259Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
2260Configure and run it again. If you can't run Configure for some reason,
2261you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 2262have, let me (perlbug@perl.org) know how I blew it.

2263
2264This installation script affects things in two ways:
2265
22661) it may do direct variable substitutions on some of the files included
2267 in this kit.
22682) it builds a config.h file for inclusion in C programs. You may edit
2269 any of these files as the need arises after running this script.
2270
2271If you make a mistake on a question, there is no easy way to back up to it
2272currently. The easiest thing to do is to edit config.sh and rerun all the SH
2273files. Configure will offer to let you do this before it runs the SH files.

3475previous run of Configure, you may specify it as well as or instead of
3476OS-specific hints. If hints are provided for your OS, you should use them:
3477although Perl can probably be built without hints on many platforms, using
3478hints often improve performance and may enable features that Configure can't
3479set up on its own. If there are no hints that match your OS, specify "none";
3480DO NOT give a wrong version or a wrong OS.
