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]

2370 This installation shell script will examine your system and ask you questions
2371 to determine how the perl5 package should be installed. If you get
2372 stuck on a question, you may use a ! shell escape to start a subshell or
2373 execute a command.  Many of the questions will have default answers in square
2374 brackets; typing carriage return will give you the default.
2375
2376 On some of the questions which ask for file or directory names you are allowed
2377 to use the ~name construct to specify the login directory belonging to "name",
2378 even if you don't have a shell which knows about that.  Questions where this is
2379 allowed will be marked "(~name ok)".

2386
2387 The prompter used in this script allows you to use shell variables and
2388 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2389 in the default answer, as if the default line was a set of arguments given to a
2390 script shell.  This means you may also use $* to repeat the whole default line,
2391 so you do not have to re-type everything to add something to the default.
2392
2393 Every time there is a substitution, you will have to confirm.  If there is an
2394 error (e.g. an unmatched backtick), the default answer will remain unchanged
2395 and you will be prompted again.
2396
2397 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2398 the questions and use the computed defaults (or the previous answers if there
2399 was already a config.sh file). Type 'Configure -h' for a list of options.
2400 You may also start interactively and then answer '& -d' at any prompt to turn
2401 on the non-interactive behaviour for the remainder of the execution.

2407 Much effort has been expended to ensure that this shell script will run on any
2408 Unix system.  If despite that it blows up on yours, your best bet is to edit
2409 Configure and run it again.  If you can't run Configure for some reason,
2410 you'll have to generate a config.sh file by hand.  Whatever problems you
2411 have, let me (perlbug@perl.org) know how I blew it.
2412
2413 This installation script affects things in two ways:
2414
2415 1) it may do direct variable substitutions on some of the files included
2416    in this kit.
2417 2) it builds a config.h file for inclusion in C programs.  You may edit
2418    any of these files as the need arises after running this script.
2419
2420 If you make a mistake on a question, there is no easy way to back up to it
2421 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2422 files.  Configure will offer to let you do this before it runs the SH files.

4721     Your gcc has not been compiled for the exact release of
4722     your operating system ($gccosandvers versus $osname$osvers).
4723
4724     In general it is a good idea to keep gcc synchronized with
4725     the operating system because otherwise serious problems
4726     may ensue when trying to compile software, like Perl.
4727
4728     I'm trying to be optimistic here, though, and will continue.
4729     If later during the configuration and build icky compilation
4730     problems appear (headerfile conflicts being the most common
4731     manifestation), I suggest reinstalling the gcc to match
4732     your operating system release.
