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.code.sf.net/p/dist/code/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.

2256 This installation shell script will examine your system and ask you questions
2257 to determine how the perl5 package should be installed. If you get
2258 stuck on a question, you may use a ! shell escape to start a subshell or
2259 execute a command.  Many of the questions will have default answers in square
2260 brackets; typing carriage return will give you the default.
2261
2262 On some of the questions which ask for file or directory names you are allowed
2263 to use the ~name construct to specify the login directory belonging to "name",
2264 even if you don't have a shell which knows about that.  Questions where this is
2265 allowed will be marked "(~name ok)".

2272
2273 The prompter used in this script allows you to use shell variables and
2274 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2275 in the default answer, as if the default line was a set of arguments given to a
2276 script shell.  This means you may also use $* to repeat the whole default line,
2277 so you do not have to re-type everything to add something to the default.
2278
2279 Every time there is a substitution, you will have to confirm.  If there is an
2280 error (e.g. an unmatched backtick), the default answer will remain unchanged
2281 and you will be prompted again.
2282
2283 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2284 the questions and use the computed defaults (or the previous answers if there
2285 was already a config.sh file). Type 'Configure -h' for a list of options.
2286 You may also start interactively and then answer '& -d' at any prompt to turn
2287 on the non-interactive behaviour for the remainder of the execution.

2293 Much effort has been expended to ensure that this shell script will run on any
2294 Unix system.  If despite that it blows up on yours, your best bet is to edit
2295 Configure and run it again.  If you can't run Configure for some reason,
2296 you'll have to generate a config.sh file by hand.  Whatever problems you
2297 have, let me (perlbug@perl.org) know how I blew it.
2298
2299 This installation script affects things in two ways:
2300
2301 1) it may do direct variable substitutions on some of the files included
2302    in this kit.
2303 2) it builds a config.h file for inclusion in C programs.  You may edit
2304    any of these files as the need arises after running this script.
2305
2306 If you make a mistake on a question, there is no easy way to back up to it
2307 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2308 files.  Configure will offer to let you do this before it runs the SH files.
