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. :-)

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...

1435This installation shell script will examine your system and ask you questions
a0d0e21e 1436to determine how the perl5 package should be installed. If you get
2304df62
AD
1437stuck on a question, you may use a ! shell escape to start a subshell or
1438execute a command. Many of the questions will have default answers in square
1439brackets; typing carriage return will give you the default.
1440
1441On some of the questions which ask for file or directory names you are allowed
1442to use the ~name construct to specify the login directory belonging to "name",
1443even if you don't have a shell which knows about that. Questions where this is
1444allowed will be marked "(~name ok)".

1449 . ./myread
1450 cat <<'EOH'
1451
1452The prompter used in this script allows you to use shell variables and
1453backticks in your answers. You may use $1, $2, etc... to refer to the words
1454in the default answer, as if the default line was a set of arguments given to a
1455script shell. This means you may also use $* to repeat the whole default line,
1456so you do not have to re-type everything to add something to the default.
1457
1458Everytime there is a substitution, you will have to confirm. If there is an
1459error (e.g. an unmatched backtick), the default answer will remain unchanged
1460and you will be prompted again.
1461
1462If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1463the questions and use the computed defaults (or the previous answers if there
1464was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1465You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1466on the non-interactive behaviour for the remainder of the execution.

1472Much effort has been expended to ensure that this shell script will run on any
1473Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1474Configure and run it again. If you can't run Configure for some reason,
1475you'll have to generate a config.sh file by hand. Whatever problems you
dfe9444c 1476have, let me (doughera@lafcol.lafayette.edu) know how I blew it.

1478This installation script affects things in two ways:
1479
14801) it may do direct variable substitutions on some of the files included
1481 in this kit.
14822) it builds a config.h file for inclusion in C programs. You may edit
1483 any of these files as the need arises after running this script.
1484
1485If you make a mistake on a question, there is no easy way to back up to it
1486currently. The easiest thing to do is to edit config.sh and rerun all the SH
1487files. Configure will offer to let you do this before it runs the SH files.

2556By default, $package will be installed in $dflt/bin, manual
2557pages under $dflt/man, etc..., i.e. with $dflt as prefix for
2558all installation directories. Typically set to /usr/local, but you
2559may choose /usr if you wish to install $package among your system
2560binaries. If you wish to have binaries under /bin but manual pages
2561under /usr/local/man, that's ok: you will be prompted separately
2562for each of the installation directories, the prefix being only used
2563to set the defaults.

3069Some systems have different model sizes. On most systems they are called
3070small, medium, large, and huge. On the PDP11 they are called unsplit and
3071split. If your system doesn't support different memory models, say "none".
3072If you wish to force everything to one memory model, say "none" here and
3073put the appropriate flags later when it asks you for other cc and ld flags.
3074Venix systems may wish to put "none" and let the compiler figure things out.
3075(In the following question multiple model names should be space separated.)

3968I can use 'nm' to extract the symbols from your C libraries. This is a time
3969consuming task which may generate huge output on the disk (up to 3 megabytes)
3970but that should make the symbols extraction faster. The alternative is to skip
3971the 'nm' extraction part and to compile a small test program instead to
3972determine whether each symbol is present. If you have a fast C compiler and/or
3973if your 'nm' output cannot be parsed, this may be the best solution.
