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.)

1303This installation shell script will examine your system and ask you questions
a0d0e21e 1304to determine how the perl5 package should be installed. If you get
2304df62
AD
1305stuck on a question, you may use a ! shell escape to start a subshell or
1306execute a command. Many of the questions will have default answers in square
1307brackets; typing carriage return will give you the default.
1308
1309On some of the questions which ask for file or directory names you are allowed
1310to use the ~name construct to specify the login directory belonging to "name",
1311even if you don't have a shell which knows about that. Questions where this is
1312allowed will be marked "(~name ok)".
1313
1314EOH
1315 rp=''
1316 dflt='Type carriage return to continue'
1317 . ./myread
1318 cat <<'EOH'
1319
1320The prompter used in this script allows you to use shell variables and
1321backticks in your answers. You may use $1, $2, etc... to refer to the words
1322in the default answer, as if the default line was a set of arguments given to a
1323script shell. This means you may also use $* to repeat the whole default line,
1324so you do not have to re-type everything to add something to the default.
1325
1326Everytime there is a substitution, you will have to confirm. If there is an
1327error (e.g. an unmatched backtick), the default answer will remain unchanged
1328and you will be prompted again.
1329
1330If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1331the questions and use the computed defaults (or the previous answers if there
1332was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424
AD
1333You may also start interactively and then answer '& -d' at any prompt to turn
1334on the non-interactive behaviour for the remaining of the execution.

1340Much effort has been expended to ensure that this shell script will run on any
1341Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1342Configure and run it again. If you can't run Configure for some reason,
1343you'll have to generate a config.sh file by hand. Whatever problems you
8ff267be 1344have, let me (doughera@lafcol.lafayette.edu) know how I blew it.

1346This installation script affects things in two ways:
1347
13481) it may do direct variable substitutions on some of the files included
1349 in this kit.
13502) it builds a config.h file for inclusion in C programs. You may edit
1351 any of these files as the need arises after running this script.
1352
1353If you make a mistake on a question, there is no easy way to back up to it
1354currently. The easiest thing to do is to edit config.sh and rerun all the SH
1355files. Configure will offer to let you do this before it runs the SH files.

3073On some systems the default C compiler will not resolve multiple global
3074references that happen to have the same name. On some such systems the "Mcc"
3075command may be used to force these to be resolved. On other systems a "cc -M"
3076command is required. (Note that the -M flag on other systems indicates a
3077memory model to use!) If you have the Gnu C compiler, you might wish to use
3078that instead.

3788I can use 'nm' to extract the symbols from your C libraries. This is a time
3789consuming task which may generate huge output on the disk (up to 3 megabytes)
3790but that should make the symbols extraction faster. The alternative is to skip
3791the 'nm' extraction part and to compile a small test program instead to
3792determine whether each symbol is present. If you have a fast C compiler and/or
3793if your 'nm' output cannot be parsed, this may be the best solution.
3794You shouldn't let me use 'nm' if you have the GNU C Library.
