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

29 SCO csh still thinks true is false. Write to SCO today and tell them that next
30 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
32 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33 we'd have to do is go in and swap the && and || tokens, wherever they are.)
35 [End of diatribe. We now return you to your regularly scheduled programming...]

1585 This installation shell script will examine your system and ask you questions
1586 to determine how the perl5 package should be installed. If you get
1587 stuck on a question, you may use a ! shell escape to start a subshell or
1588 execute a command. Many of the questions will have default answers in square
1589 brackets; typing carriage return will give you the default.
1591 On some of the questions which ask for file or directory names you are allowed
1592 to use the ~name construct to specify the login directory belonging to "name",
1593 even if you don't have a shell which knows about that. Questions where this is
1594 allowed will be marked "(~name ok)".
1598 dflt='Type carriage return to continue'
1602 The prompter used in this script allows you to use shell variables and
1603 backticks in your answers. You may use $1, $2, etc... to refer to the words
1604 in the default answer, as if the default line was a set of arguments given to a
1605 script shell. This means you may also use $* to repeat the whole default line,
1606 so you do not have to re-type everything to add something to the default.
1608 Everytime there is a substitution, you will have to confirm. If there is an
1609 error (e.g. an unmatched backtick), the default answer will remain unchanged
1610 and you will be prompted again.
1612 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1613 the questions and use the computed defaults (or the previous answers if there
1614 was already a config.sh file). Type 'Configure -h' for a list of options.
1615 You may also start interactively and then answer '& -d' at any prompt to turn
1616 on the non-interactive behaviour for the remainder of the execution.
1622 Much effort has been expended to ensure that this shell script will run on any
1623 Unix system. If despite that it blows up on yours, your best bet is to edit
1624 Configure and run it again. If you can't run Configure for some reason,
1625 you'll have to generate a config.sh file by hand. Whatever problems you
1626 have, let me (jhi@iki.fi) know how I blew it.
1628 This installation script affects things in two ways:
1630 1) it may do direct variable substitutions on some of the files included
1632 2) it builds a config.h file for inclusion in C programs. You may edit
1633 any of these files as the need arises after running this script.
1635 If you make a mistake on a question, there is no easy way to back up to it
1636 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1637 files. Configure will offer to let you do this before it runs the SH files.

3878 Some versions of Unix support shared libraries, which make executables smaller
3879 but make load time slightly longer.
3881 On some systems, mostly System V Release 3's, the shared library is included
3882 by putting the option "-lc_s" as the last thing on the cc command line when
3883 linking. Other systems use shared libraries by default. There may be other
3884 libraries needed to compile $package on your machine as well. If your system
3885 needs the "-lc_s" option, include it here. Include any other special libraries
3886 here as well. Say "none" for none.
