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. Rather than
  15 # working with this copy of Configure, you may wish to get metaconfig.
  16 # The dist package (which contains metaconfig) is available via SVN:
  17 #     svn co https://svn.sourceforge.net/svnroot/dist/trunk/dist
  18 #
  19 # Though this script was generated by metaconfig from metaunits, it is
  20 # OK to send patches against Configure itself. It's up to the Configure
  21 # pumpkin to backport the patch to the metaunits if it is accepted.
  22 # For more information on patching Configure, see pod/perlhack.pod
  23 #
  24 # The metaunits are also available from the public git repository:
  25 #     http://perl5.git.perl.org/metaconfig.git/ or
  26 #     $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
  27 #
  28 # See Porting/pumpkin.pod for more information on metaconfig.

2234 This installation shell script will examine your system and ask you questions
2235 to determine how the perl5 package should be installed. If you get
2236 stuck on a question, you may use a ! shell escape to start a subshell or
2237 execute a command.  Many of the questions will have default answers in square
2238 brackets; typing carriage return will give you the default.
2239
2240 On some of the questions which ask for file or directory names you are allowed
2241 to use the ~name construct to specify the login directory belonging to "name",
2242 even if you don't have a shell which knows about that.  Questions where this is
2243 allowed will be marked "(~name ok)".

2250
2251 The prompter used in this script allows you to use shell variables and
2252 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2253 in the default answer, as if the default line was a set of arguments given to a
2254 script shell.  This means you may also use $* to repeat the whole default line,
2255 so you do not have to re-type everything to add something to the default.
2256
2257 Everytime there is a substitution, you will have to confirm.  If there is an
2258 error (e.g. an unmatched backtick), the default answer will remain unchanged
2259 and you will be prompted again.
2260
2261 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2262 the questions and use the computed defaults (or the previous answers if there
2263 was already a config.sh file). Type 'Configure -h' for a list of options.
2264 You may also start interactively and then answer '& -d' at any prompt to turn
2265 on the non-interactive behaviour for the remainder of the execution.

2271 Much effort has been expended to ensure that this shell script will run on any
2272 Unix system.  If despite that it blows up on yours, your best bet is to edit
2273 Configure and run it again.  If you can't run Configure for some reason,
2274 you'll have to generate a config.sh file by hand.  Whatever problems you
2275 have, let me (perlbug@perl.org) know how I blew it.
2276
2277 This installation script affects things in two ways:
2278
2279 1) it may do direct variable substitutions on some of the files included
2280    in this kit.
2281 2) it builds a config.h file for inclusion in C programs.  You may edit
2282    any of these files as the need arises after running this script.
2283
2284 If you make a mistake on a question, there is no easy way to back up to it
2285 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2286 files.  Configure will offer to let you do this before it runs the SH files.

4241 Since release 5.6, Perl has had two different threading implementations,
4242 the newer interpreter-based version (ithreads) with one interpreter per
4243 thread, and the older 5.005 version (5005threads).
4244 The 5005threads version is effectively unmaintained and will probably be
4245 removed in Perl 5.10, so there should be no need to build a Perl using it
4246 unless needed for backwards compatibility with some existing 5.005threads
4247 code.
