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.)
10#
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.)

1356This installation shell script will examine your system and ask you questions
a0d0e21e 1357to determine how the perl5 package should be installed. If you get
2304df62
AD
1358stuck on a question, you may use a ! shell escape to start a subshell or
1359execute a command. Many of the questions will have default answers in square
1360brackets; typing carriage return will give you the default.
1361
1362On some of the questions which ask for file or directory names you are allowed
1363to use the ~name construct to specify the login directory belonging to "name",
1364even if you don't have a shell which knows about that. Questions where this is
1365allowed will be marked "(~name ok)".
1366
1367EOH

1369 dflt='Type carriage return to continue'
1370 . ./myread
1371 cat <<'EOH'
1372
1373The prompter used in this script allows you to use shell variables and
1374backticks in your answers. You may use $1, $2, etc... to refer to the words
1375in the default answer, as if the default line was a set of arguments given to a
1376script shell. This means you may also use $* to repeat the whole default line,
1377so you do not have to re-type everything to add something to the default.
1378
1379Everytime there is a substitution, you will have to confirm. If there is an
1380error (e.g. an unmatched backtick), the default answer will remain unchanged
1381and you will be prompted again.
1382
1383If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1384the questions and use the computed defaults (or the previous answers if there
1385was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1386You may also start interactively and then answer '& -d' at any prompt to turn
7bac28a0 1387on the non-interactive behavior for the remainder of the execution.

1393Much effort has been expended to ensure that this shell script will run on any
1394Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1395Configure and run it again. If you can't run Configure for some reason,
1396you'll have to generate a config.sh file by hand. Whatever problems you
284c50cc 1397have, let me (chip@perl.com) know how I blew it.

1399This installation script affects things in two ways:
1400
14011) it may do direct variable substitutions on some of the files included
1402 in this kit.
14032) it builds a config.h file for inclusion in C programs. You may edit
1404 any of these files as the need arises after running this script.
1405
1406If you make a mistake on a question, there is no easy way to back up to it
1407currently. The easiest thing to do is to edit config.sh and rerun all the SH
1408files. Configure will offer to let you do this before it runs the SH files.

3051Some systems have different model sizes. On most systems they are called
3052small, medium, large, and huge. On the PDP11 they are called unsplit and
3053split. If your system doesn't support different memory models, say "none".
3054If you wish to force everything to one memory model, say "none" here and
3055put the appropriate flags later when it asks you for other cc and ld flags.
3056Venix systems may wish to put "none" and let the compiler figure things out.
3057(In the following question multiple model names should be space separated.)

3904I can use 'nm' to extract the symbols from your C libraries. This is a time
3905consuming task which may generate huge output on the disk (up to 3 megabytes)
3906but that should make the symbols extraction faster. The alternative is to skip
3907the 'nm' extraction part and to compile a small test program instead to
3908determine whether each symbol is present. If you have a fast C compiler and/or
3909if your 'nm' output cannot be parsed, this may be the best solution.
3910You shouldn't let me use 'nm' if you have the GNU C Library.
