Configure

   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 by the tool
  15 # called "metaconfig". Rather than working with this copy of Configure,
  16 # you should use metaconfig. Perl uses a modified version of this
  17 # tool, and this, together with the metaconfig units, are available
  18 # in the git repository:
  19 #    $ git clone https://github.com/perl5-metaconfig/metaconfig metaconfig
  20 # The original dist package (including metaconfig) is available on github:
  21 #    $ git clone https://github.com/rmanfredi/dist.git dist-git
  22 #
  23 # Though this script was generated by metaconfig from metaunits, it is
  24 # OK to send patches against Configure itself (but not to commit them
  25 # to blead). It's up to
  26 # the Configure maintainers to backport the patch to the metaunits if it
  27 # is accepted. Exceptions to this rule, and more information, is in
  28 # Porting/pumpkin.pod.

  30 # Generated using [metaconfig 3.5 PL0]

2346 This installation shell script will examine your system and ask you questions
2347 to determine how the perl5 package should be installed. If you get
2348 stuck on a question, you may use a ! shell escape to start a subshell or
2349 execute a command.  Many of the questions will have default answers in square
2350 brackets; typing carriage return will give you the default.
2351
2352 On some of the questions which ask for file or directory names you are allowed
2353 to use the ~name construct to specify the login directory belonging to "name",
2354 even if you don't have a shell which knows about that.  Questions where this is
2355 allowed will be marked "(~name ok)".

2362
2363 The prompter used in this script allows you to use shell variables and
2364 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2365 in the default answer, as if the default line was a set of arguments given to a
2366 script shell.  This means you may also use $* to repeat the whole default line,
2367 so you do not have to re-type everything to add something to the default.
2368
2369 Every time there is a substitution, you will have to confirm.  If there is an
2370 error (e.g. an unmatched backtick), the default answer will remain unchanged
2371 and you will be prompted again.
2372
2373 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2374 the questions and use the computed defaults (or the previous answers if there
2375 was already a config.sh file). Type 'Configure -h' for a list of options.
2376 You may also start interactively and then answer '& -d' at any prompt to turn
2377 on the non-interactive behaviour for the remainder of the execution.

2383 Much effort has been expended to ensure that this shell script will run on any
2384 Unix system.  If despite that it blows up on yours, your best bet is to edit
2385 Configure and run it again.  If you can't run Configure for some reason,
2386 you'll have to generate a config.sh file by hand.  Whatever problems you
2387 have, let me (perlbug@perl.org) know how I blew it.
2388
2389 This installation script affects things in two ways:
2390
2391 1) it may do direct variable substitutions on some of the files included
2392    in this kit.
2393 2) it builds a config.h file for inclusion in C programs.  You may edit
2394    any of these files as the need arises after running this script.
2395
2396 If you make a mistake on a question, there is no easy way to back up to it
2397 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2398 files.  Configure will offer to let you do this before it runs the SH files.

4699     In general it is a good idea to keep gcc synchronized with
4700     the operating system because otherwise serious problems
4701     may ensue when trying to compile software, like Perl.
4702
4703     I'm trying to be optimistic here, though, and will continue.
4704     If later during the configuration and build icky compilation
4705     problems appear (headerfile conflicts being the most common
4706     manifestation), I suggest reinstalling the gcc to match
4707     your operating system release.
