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 may wish to get metaconfig. Perl uses a modified version of this
  17 # tool, available in the "dist" folder in the checkout of the git repo
  18 #    $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
  19 # The original dist package (including metaconfig) is available via SVN:
  20 #    $ svn co https://svn.code.sf.net/p/dist/code/trunk/dist
  21 #
  22 # Though this script was generated by metaconfig from metaunits, it is
  23 # OK to send patches against Configure itself. It's up to the Configure
  24 # pumpkin to backport the patch to the metaunits if it is accepted.
  25 # For more information on patching Configure, see pod/perlhack.pod
  26 #
  27 # The metaunits are also available from the public git repository:
  28 #     http://perl5.git.perl.org/metaconfig.git/ or
  29 #     $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
  30 #
  31 # See Porting/pumpkin.pod for more information on metaconfig.
  32
  33 # Generated using [metaconfig 3.5 PL0]

2352 This installation shell script will examine your system and ask you questions
2353 to determine how the perl5 package should be installed. If you get
2354 stuck on a question, you may use a ! shell escape to start a subshell or
2355 execute a command.  Many of the questions will have default answers in square
2356 brackets; typing carriage return will give you the default.
2357
2358 On some of the questions which ask for file or directory names you are allowed
2359 to use the ~name construct to specify the login directory belonging to "name",
2360 even if you don't have a shell which knows about that.  Questions where this is
2361 allowed will be marked "(~name ok)".

2368
2369 The prompter used in this script allows you to use shell variables and
2370 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2371 in the default answer, as if the default line was a set of arguments given to a
2372 script shell.  This means you may also use $* to repeat the whole default line,
2373 so you do not have to re-type everything to add something to the default.
2374
2375 Every time there is a substitution, you will have to confirm.  If there is an
2376 error (e.g. an unmatched backtick), the default answer will remain unchanged
2377 and you will be prompted again.
2378
2379 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2380 the questions and use the computed defaults (or the previous answers if there
2381 was already a config.sh file). Type 'Configure -h' for a list of options.
2382 You may also start interactively and then answer '& -d' at any prompt to turn
2383 on the non-interactive behaviour for the remainder of the execution.

2389 Much effort has been expended to ensure that this shell script will run on any
2390 Unix system.  If despite that it blows up on yours, your best bet is to edit
2391 Configure and run it again.  If you can't run Configure for some reason,
2392 you'll have to generate a config.sh file by hand.  Whatever problems you
2393 have, let me (perlbug@perl.org) know how I blew it.
2394
2395 This installation script affects things in two ways:
2396
2397 1) it may do direct variable substitutions on some of the files included
2398    in this kit.
2399 2) it builds a config.h file for inclusion in C programs.  You may edit
2400    any of these files as the need arises after running this script.
2401
2402 If you make a mistake on a question, there is no easy way to back up to it
2403 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2404 files.  Configure will offer to let you do this before it runs the SH files.

4706     In general it is a good idea to keep gcc synchronized with
4707     the operating system because otherwise serious problems
4708     may ensue when trying to compile software, like Perl.
4709
4710     I'm trying to be optimistic here, though, and will continue.
4711     If later during the configuration and build icky compilation
4712     problems appear (headerfile conflicts being the most common
4713     manifestation), I suggest reinstalling the gcc to match
4714     your operating system release.
