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.

2233 This installation shell script will examine your system and ask you questions
2234 to determine how the perl5 package should be installed. If you get
2235 stuck on a question, you may use a ! shell escape to start a subshell or
2236 execute a command.  Many of the questions will have default answers in square
2237 brackets; typing carriage return will give you the default.
2238
2239 On some of the questions which ask for file or directory names you are allowed
2240 to use the ~name construct to specify the login directory belonging to "name",
2241 even if you don't have a shell which knows about that.  Questions where this is
2242 allowed will be marked "(~name ok)".

2249
2250 The prompter used in this script allows you to use shell variables and
2251 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2252 in the default answer, as if the default line was a set of arguments given to a
2253 script shell.  This means you may also use $* to repeat the whole default line,
2254 so you do not have to re-type everything to add something to the default.
2255
2256 Every time there is a substitution, you will have to confirm.  If there is an
2257 error (e.g. an unmatched backtick), the default answer will remain unchanged
2258 and you will be prompted again.
2259
2260 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2261 the questions and use the computed defaults (or the previous answers if there
2262 was already a config.sh file). Type 'Configure -h' for a list of options.
2263 You may also start interactively and then answer '& -d' at any prompt to turn
2264 on the non-interactive behaviour for the remainder of the execution.

2270 Much effort has been expended to ensure that this shell script will run on any
2271 Unix system.  If despite that it blows up on yours, your best bet is to edit
2272 Configure and run it again.  If you can't run Configure for some reason,
2273 you'll have to generate a config.sh file by hand.  Whatever problems you
2274 have, let me (perlbug@perl.org) know how I blew it.
2275
2276 This installation script affects things in two ways:
2277
2278 1) it may do direct variable substitutions on some of the files included
2279    in this kit.
2280 2) it builds a config.h file for inclusion in C programs.  You may edit
2281    any of these files as the need arises after running this script.
2282
2283 If you make a mistake on a question, there is no easy way to back up to it
2284 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2285 files.  Configure will offer to let you do this before it runs the SH files.
