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]

2355 This installation shell script will examine your system and ask you questions
2356 to determine how the perl5 package should be installed. If you get
2357 stuck on a question, you may use a ! shell escape to start a subshell or
2358 execute a command.  Many of the questions will have default answers in square
2359 brackets; typing carriage return will give you the default.
2360
2361 On some of the questions which ask for file or directory names you are allowed
2362 to use the ~name construct to specify the login directory belonging to "name",
2363 even if you don't have a shell which knows about that.  Questions where this is
2364 allowed will be marked "(~name ok)".

2371
2372 The prompter used in this script allows you to use shell variables and
2373 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2374 in the default answer, as if the default line was a set of arguments given to a
2375 script shell.  This means you may also use $* to repeat the whole default line,
2376 so you do not have to re-type everything to add something to the default.
2377
2378 Every time there is a substitution, you will have to confirm.  If there is an
2379 error (e.g. an unmatched backtick), the default answer will remain unchanged
2380 and you will be prompted again.
2381
2382 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2383 the questions and use the computed defaults (or the previous answers if there
2384 was already a config.sh file). Type 'Configure -h' for a list of options.
2385 You may also start interactively and then answer '& -d' at any prompt to turn
2386 on the non-interactive behaviour for the remainder of the execution.

2392 Much effort has been expended to ensure that this shell script will run on any
2393 Unix system.  If despite that it blows up on yours, your best bet is to edit
2394 Configure and run it again.  If you can't run Configure for some reason,
2395 you'll have to generate a config.sh file by hand.  Whatever problems you
2396 have, let me (perlbug@perl.org) know how I blew it.
2397
2398 This installation script affects things in two ways:
2399
2400 1) it may do direct variable substitutions on some of the files included
2401    in this kit.
2402 2) it builds a config.h file for inclusion in C programs.  You may edit
2403    any of these files as the need arises after running this script.
2404
2405 If you make a mistake on a question, there is no easy way to back up to it
2406 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2407 files.  Configure will offer to let you do this before it runs the SH files.

4709     In general it is a good idea to keep gcc synchronized with
4710     the operating system because otherwise serious problems
4711     may ensue when trying to compile software, like Perl.
4712
4713     I'm trying to be optimistic here, though, and will continue.
4714     If later during the configuration and build icky compilation
4715     problems appear (headerfile conflicts being the most common
4716     manifestation), I suggest reinstalling the gcc to match
4717     your operating system release.
