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.)

1170This installation shell script will examine your system and ask you questions
a0d0e21e 1171to determine how the perl5 package should be installed. If you get
2304df62
AD
1172stuck on a question, you may use a ! shell escape to start a subshell or
1173execute a command. Many of the questions will have default answers in square
1174brackets; typing carriage return will give you the default.
1175
1176On some of the questions which ask for file or directory names you are allowed
1177to use the ~name construct to specify the login directory belonging to "name",
1178even if you don't have a shell which knows about that. Questions where this is
1179allowed will be marked "(~name ok)".
1180
1181EOH
1182 rp=''
1183 dflt='Type carriage return to continue'
1184 . ./myread
1185 cat <<'EOH'
1186
1187The prompter used in this script allows you to use shell variables and
1188backticks in your answers. You may use $1, $2, etc... to refer to the words
1189in the default answer, as if the default line was a set of arguments given to a
1190script shell. This means you may also use $* to repeat the whole default line,
1191so you do not have to re-type everything to add something to the default.
1192
1193Everytime there is a substitution, you will have to confirm. If there is an
1194error (e.g. an unmatched backtick), the default answer will remain unchanged
1195and you will be prompted again.
1196
1197If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1198the questions and use the computed defaults (or the previous answers if there
1199was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424
AD
1200You may also start interactively and then answer '& -d' at any prompt to turn
1201on the non-interactive behaviour for the remaining of the execution.

1207Much effort has been expended to ensure that this shell script will run on any
1208Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1209Configure and run it again. If you can't run Configure for some reason,
1210you'll have to generate a config.sh file by hand. Whatever problems you
c07a80fd 1211have, let me (lwall@sems.com) know how I blew it.

1213This installation script affects things in two ways:
1214
12151) it may do direct variable substitutions on some of the files included
1216 in this kit.
12172) it builds a config.h file for inclusion in C programs. You may edit
1218 any of these files as the need arises after running this script.
1219
1220If you make a mistake on a question, there is no easy way to back up to it
1221currently. The easiest thing to do is to edit config.sh and rerun all the SH
1222files. Configure will offer to let you do this before it runs the SH files.

3078On some systems the default C compiler will not resolve multiple global
3079references that happen to have the same name. On some such systems the "Mcc"
3080command may be used to force these to be resolved. On other systems a "cc -M"
3081command is required. (Note that the -M flag on other systems indicates a
3082memory model to use!) If you have the Gnu C compiler, you might wish to use
3083that instead.
