   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
  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.)

2061 This installation shell script will examine your system and ask you questions
2062 to determine how the perl5 package should be installed. If you get
2063 stuck on a question, you may use a ! shell escape to start a subshell or
2064 execute a command.  Many of the questions will have default answers in square
2065 brackets; typing carriage return will give you the default.
2066
2067 On some of the questions which ask for file or directory names you are allowed
2068 to use the ~name construct to specify the login directory belonging to "name",
2069 even if you don't have a shell which knows about that.  Questions where this is
2070 allowed will be marked "(~name ok)".

2078 The prompter used in this script allows you to use shell variables and
2079 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2080 in the default answer, as if the default line was a set of arguments given to a
2081 script shell.  This means you may also use $* to repeat the whole default line,
2082 so you do not have to re-type everything to add something to the default.
2083
2084 Everytime there is a substitution, you will have to confirm.  If there is an
2085 error (e.g. an unmatched backtick), the default answer will remain unchanged
2086 and you will be prompted again.
2087
2088 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2089 the questions and use the computed defaults (or the previous answers if there
2090 was already a config.sh file). Type 'Configure -h' for a list of options.
2091 You may also start interactively and then answer '& -d' at any prompt to turn
2092 on the non-interactive behaviour for the remainder of the execution.

2098 Much effort has been expended to ensure that this shell script will run on any

2100 Configure and run it again.  If you can't run Configure for some reason,
2101 you'll have to generate a config.sh file by hand.  Whatever problems you
2102 have, let me (perlbug@perl.org) know how I blew it.

2104 This installation script affects things in two ways:
2105
2106 1) it may do direct variable substitutions on some of the files included
2107    in this kit.
2108 2) it builds a config.h file for inclusion in C programs.  You may edit
2109    any of these files as the need arises after running this script.
2110
2111 If you make a mistake on a question, there is no easy way to back up to it
2112 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2113 files.  Configure will offer to let you do this before it runs the SH files.

3833     Your gcc has not been compiled for the exact release of
3834     your operating system ($gccosandvers versus $osname$osvers).
3835
3836     In general it is a good idea to keep gcc synchronized with
3837     the operating system because otherwise serious problems
3838     may ensue when trying to compile software, like Perl.
3839
3840     I'm trying to be optimistic here, though, and will continue.
3841     If later during the configuration and build icky compilation
3842     problems appear (headerfile conflicts being the most common
3843     manifestation), I suggest reinstalling the gcc to match
3844     your operating system release.
