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.

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.)

29SCO csh still thinks true is false. Write to SCO today and tell them that next
30year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31
32(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33we'd have to do is go in and swap the && and || tokens, wherever they are.)

2304df62 1607This installation shell script will examine your system and ask you questions
a0d0e21e 1608to determine how the perl5 package should be installed. If you get
2304df62
AD
1609stuck on a question, you may use a ! shell escape to start a subshell or
1610execute a command. Many of the questions will have default answers in square
1611brackets; typing carriage return will give you the default.
1612
1613On some of the questions which ask for file or directory names you are allowed
1614to use the ~name construct to specify the login directory belonging to "name",
1615even if you don't have a shell which knows about that. Questions where this is
1616allowed will be marked "(~name ok)".

1621 . ./myread
1622 cat <<'EOH'
1623
1624The prompter used in this script allows you to use shell variables and
1625backticks in your answers. You may use $1, $2, etc... to refer to the words
1626in the default answer, as if the default line was a set of arguments given to a
1627script shell. This means you may also use $* to repeat the whole default line,
1628so you do not have to re-type everything to add something to the default.
1629
1630Everytime there is a substitution, you will have to confirm. If there is an
1631error (e.g. an unmatched backtick), the default answer will remain unchanged
1632and you will be prompted again.
1633
1634If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1635the questions and use the computed defaults (or the previous answers if there
1636was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1637You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1638on the non-interactive behaviour for the remainder of the execution.

1644Much effort has been expended to ensure that this shell script will run on any
1645Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1646Configure and run it again. If you can't run Configure for some reason,
1647you'll have to generate a config.sh file by hand. Whatever problems you
5ff3f7a4 1648have, let me (jhi@iki.fi) know how I blew it.

1650This installation script affects things in two ways:
1651
16521) it may do direct variable substitutions on some of the files included
1653 in this kit.
16542) it builds a config.h file for inclusion in C programs. You may edit
1655 any of these files as the need arises after running this script.
1656
1657If you make a mistake on a question, there is no easy way to back up to it
1658currently. The easiest thing to do is to edit config.sh and rerun all the SH
1659files. Configure will offer to let you do this before it runs the SH files.

3349Some systems have different model sizes. On most systems they are called
3350small, medium, large, and huge. On the PDP11 they are called unsplit and
3351split. If your system doesn't support different memory models, say "none".
3352If you wish to force everything to one memory model, say "none" here and
3353put the appropriate flags later when it asks you for other cc and ld flags.
3354Venix systems may wish to put "none" and let the compiler figure things out.
3355(In the following question multiple model names should be space separated.)
