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.)

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...]
39 OOPS! You naughty creature! You didn't run Configure with sh!
40 I will attempt to remedy the situation by running sh for you...

2122 This installation shell script will examine your system and ask you questions
2123 to determine how the perl5 package should be installed. If you get
2124 stuck on a question, you may use a ! shell escape to start a subshell or
2125 execute a command. Many of the questions will have default answers in square
2126 brackets; typing carriage return will give you the default.
2128 On some of the questions which ask for file or directory names you are allowed
2129 to use the ~name construct to specify the login directory belonging to "name",
2130 even if you don't have a shell which knows about that. Questions where this is
2131 allowed will be marked "(~name ok)".
2135 dflt='Type carriage return to continue'
2139 The prompter used in this script allows you to use shell variables and
2140 backticks in your answers. You may use $1, $2, etc... to refer to the words
2141 in the default answer, as if the default line was a set of arguments given to a
2142 script shell. This means you may also use $* to repeat the whole default line,
2143 so you do not have to re-type everything to add something to the default.
2145 Everytime there is a substitution, you will have to confirm. If there is an
2146 error (e.g. an unmatched backtick), the default answer will remain unchanged
2147 and you will be prompted again.
2149 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2150 the questions and use the computed defaults (or the previous answers if there
2151 was already a config.sh file). Type 'Configure -h' for a list of options.
2152 You may also start interactively and then answer '& -d' at any prompt to turn
2153 on the non-interactive behaviour for the remainder of the execution.
2159 Much effort has been expended to ensure that this shell script will run on any
2160 Unix system. If despite that it blows up on yours, your best bet is to edit
2161 Configure and run it again. If you can't run Configure for some reason,
2162 you'll have to generate a config.sh file by hand. Whatever problems you
2163 have, let me (perlbug@perl.org) know how I blew it.
2165 This installation script affects things in two ways:
2167 1) it may do direct variable substitutions on some of the files included
2169 2) it builds a config.h file for inclusion in C programs. You may edit
2170 any of these files as the need arises after running this script.
2172 If you make a mistake on a question, there is no easy way to back up to it
2173 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2174 files. Configure will offer to let you do this before it runs the SH files.

21466 If you'd like to make any changes to the config.sh file before I begin
21467 to configure things, do it as a shell escape now (e.g. !vi config.sh).

21497 Now you need to generate make dependencies by running "$make depend".
21498 You might prefer to run it in background: "$make depend > makedepend.out &"
21499 It can take a while, so you might not want to run it right now.

21524 If you compile $package on a different machine or from a different object
21525 directory, copy the Policy.sh file from this object directory to the
21526 new one before you run Configure -- this will help you with most of
21527 the policy defaults.
