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.
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
17# comp.sources.misc so you may fetch it yourself from your nearest
18# archive site. Check with Archie if you don't know where that can be.)

28SCO csh still thinks true is false. Write to SCO today and tell them that next
29year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

31(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
32we'd have to do is go in and swap the && and || tokens, wherever they are.)

1336This installation shell script will examine your system and ask you questions
a0d0e21e 1337to determine how the perl5 package should be installed. If you get
2304df62
AD
1338stuck on a question, you may use a ! shell escape to start a subshell or
1339execute a command. Many of the questions will have default answers in square
1340brackets; typing carriage return will give you the default.
1341
1342On some of the questions which ask for file or directory names you are allowed
1343to use the ~name construct to specify the login directory belonging to "name",
1344even if you don't have a shell which knows about that. Questions where this is
1345allowed will be marked "(~name ok)".
1346
1347EOH
1348 rp=''
1349 dflt='Type carriage return to continue'
1350 . ./myread
1351 cat <<'EOH'
1352
1353The prompter used in this script allows you to use shell variables and
1354backticks in your answers. You may use $1, $2, etc... to refer to the words
1355in the default answer, as if the default line was a set of arguments given to a
1356script shell. This means you may also use $* to repeat the whole default line,
1357so you do not have to re-type everything to add something to the default.
1358
1359Everytime there is a substitution, you will have to confirm. If there is an
1360error (e.g. an unmatched backtick), the default answer will remain unchanged
1361and you will be prompted again.
1362
1363If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1364the questions and use the computed defaults (or the previous answers if there
1365was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1366You may also start interactively and then answer '& -d' at any prompt to turn
7bac28a0 1367on the non-interactive behavior for the remainder of the execution.

1373Much effort has been expended to ensure that this shell script will run on any
1374Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1375Configure and run it again. If you can't run Configure for some reason,
1376you'll have to generate a config.sh file by hand. Whatever problems you
284c50cc 1377have, let me (chip@perl.com) know how I blew it.

1379This installation script affects things in two ways:
1380
13811) it may do direct variable substitutions on some of the files included
1382 in this kit.
13832) it builds a config.h file for inclusion in C programs. You may edit
1384 any of these files as the need arises after running this script.
1385
1386If you make a mistake on a question, there is no easy way to back up to it
1387currently. The easiest thing to do is to edit config.sh and rerun all the SH
1388files. Configure will offer to let you do this before it runs the SH files.

3036Some systems have different model sizes. On most systems they are called
3037small, medium, large, and huge. On the PDP11 they are called unsplit and
3038split. If your system doesn't support different memory models, say "none".
3039If you wish to force everything to one memory model, say "none" here and
3040put the appropriate flags later when it asks you for other cc and ld flags.
3041Venix systems may wish to put "none" and let the compiler figure things out.
3042(In the following question multiple model names should be space separated.)

3889I can use 'nm' to extract the symbols from your C libraries. This is a time
3890consuming task which may generate huge output on the disk (up to 3 megabytes)
3891but that should make the symbols extraction faster. The alternative is to skip
3892the 'nm' extraction part and to compile a small test program instead to
3893determine whether each symbol is present. If you have a fast C compiler and/or
3894if your 'nm' output cannot be parsed, this may be the best solution.
