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
dfe9444c
AD
17# comp.sources.misc and is available on CPAN under authors/id/RAM so
18# you may fetch it yourself from your nearest archive site.)

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. :-)
30
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.)

39I will attempt to remedy the situation by running sh for you...

2304df62 1470This installation shell script will examine your system and ask you questions
a0d0e21e 1471to determine how the perl5 package should be installed. If you get
2304df62
AD
1472stuck on a question, you may use a ! shell escape to start a subshell or
1473execute a command. Many of the questions will have default answers in square
1474brackets; typing carriage return will give you the default.
1475
1476On some of the questions which ask for file or directory names you are allowed
1477to use the ~name construct to specify the login directory belonging to "name",
1478even if you don't have a shell which knows about that. Questions where this is
1479allowed will be marked "(~name ok)".

1484 . ./myread
1485 cat <<'EOH'
1486
1487The prompter used in this script allows you to use shell variables and
1488backticks in your answers. You may use $1, $2, etc... to refer to the words
1489in the default answer, as if the default line was a set of arguments given to a
1490script shell. This means you may also use $* to repeat the whole default line,
1491so you do not have to re-type everything to add something to the default.
1492
1493Everytime there is a substitution, you will have to confirm. If there is an
1494error (e.g. an unmatched backtick), the default answer will remain unchanged
1495and you will be prompted again.
1496
1497If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1498the questions and use the computed defaults (or the previous answers if there
1499was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1500You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1501on the non-interactive behaviour for the remainder of the execution.

1507Much effort has been expended to ensure that this shell script will run on any

40000a8c
AD
1509Configure and run it again. If you can't run Configure for some reason,
1510you'll have to generate a config.sh file by hand. Whatever problems you

1513This installation script affects things in two ways:
1514
15151) it may do direct variable substitutions on some of the files included
1516 in this kit.
15172) it builds a config.h file for inclusion in C programs. You may edit
1518 any of these files as the need arises after running this script.
1519
1520If you make a mistake on a question, there is no easy way to back up to it
1521currently. The easiest thing to do is to edit config.sh and rerun all the SH
1522files. Configure will offer to let you do this before it runs the SH files.

3084Some systems have different model sizes. On most systems they are called
3085small, medium, large, and huge. On the PDP11 they are called unsplit and
3086split. If your system doesn't support different memory models, say "none".
3087If you wish to force everything to one memory model, say "none" here and
3088put the appropriate flags later when it asks you for other cc and ld flags.
3089Venix systems may wish to put "none" and let the compiler figure things out.
3090(In the following question multiple model names should be space separated.)
3091
3092The default for most systems is "none".

3214On some older systems the default C compiler will not resolve multiple global

3216command may be used to force these to be resolved. On other systems a "cc -M"
3217command is required. (Note that the -M flag on other systems indicates a
3218memory model to use!) If you have the Gnu C compiler, you might wish to use
3219that instead.
