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.)

1293This installation shell script will examine your system and ask you questions
a0d0e21e 1294to determine how the perl5 package should be installed. If you get
2304df62
AD
1295stuck on a question, you may use a ! shell escape to start a subshell or
1296execute a command. Many of the questions will have default answers in square
1297brackets; typing carriage return will give you the default.
1298
1299On some of the questions which ask for file or directory names you are allowed
1300to use the ~name construct to specify the login directory belonging to "name",
1301even if you don't have a shell which knows about that. Questions where this is
1302allowed will be marked "(~name ok)".
1303
1304EOH
1305 rp=''
1306 dflt='Type carriage return to continue'
1307 . ./myread
1308 cat <<'EOH'
1309
1310The prompter used in this script allows you to use shell variables and
1311backticks in your answers. You may use $1, $2, etc... to refer to the words
1312in the default answer, as if the default line was a set of arguments given to a
1313script shell. This means you may also use $* to repeat the whole default line,
1314so you do not have to re-type everything to add something to the default.
1315
1316Everytime there is a substitution, you will have to confirm. If there is an
1317error (e.g. an unmatched backtick), the default answer will remain unchanged
1318and you will be prompted again.
1319
1320If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1321the questions and use the computed defaults (or the previous answers if there
1322was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424
AD
1323You may also start interactively and then answer '& -d' at any prompt to turn
1324on the non-interactive behaviour for the remaining of the execution.

1330Much effort has been expended to ensure that this shell script will run on any
1331Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1332Configure and run it again. If you can't run Configure for some reason,
1333you'll have to generate a config.sh file by hand. Whatever problems you
8ff267be 1334have, let me (doughera@lafcol.lafayette.edu) know how I blew it.

1336This installation script affects things in two ways:
1337
13381) it may do direct variable substitutions on some of the files included
1339 in this kit.
13402) it builds a config.h file for inclusion in C programs. You may edit
1341 any of these files as the need arises after running this script.
1342
1343If you make a mistake on a question, there is no easy way to back up to it
1344currently. The easiest thing to do is to edit config.sh and rerun all the SH
1345files. Configure will offer to let you do this before it runs the SH files.

3172Some systems have different model sizes. On most systems they are called
3173small, medium, large, and huge. On the PDP11 they are called unsplit and
3174split. If your system doesn't support different memory models, say "none".
3175If you wish to force everything to one memory model, say "none" here and
3176put the appropriate flags later when it asks you for other cc and ld flags.
3177Venix systems may wish to put "none" and let the compiler figure things out.
3178(In the following question multiple model names should be space separated.)

4183Your C linker may need flags. For this question you should
4184include -L/whatever and any other flags used by the C linker, but you
4185should NOT include libraries like -lwhatever.
4186
4187Make sure you include the appropriate -L/path flags if your C linker
4188does not normally search all of the directories you specified above,
4189namely
4190 $libpth
4191To use no flags, specify the word "none".
