   4 # shell scripts, Configure will trim # comments from them for you.

   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-3.0 package (which contains metaconfig) was posted in
  17 # comp.sources.misc and is available on CPAN under authors/id/RAM so
  18 # you may fetch it yourself from your nearest archive site.)

1906 This installation shell script will examine your system and ask you questions
1907 to determine how the perl5 package should be installed. If you get
1908 stuck on a question, you may use a ! shell escape to start a subshell or
1909 execute a command.  Many of the questions will have default answers in square
1910 brackets; typing carriage return will give you the default.
1911
1912 On some of the questions which ask for file or directory names you are allowed
1913 to use the ~name construct to specify the login directory belonging to "name",
1914 even if you don't have a shell which knows about that.  Questions where this is
1915 allowed will be marked "(~name ok)".

1923 The prompter used in this script allows you to use shell variables and
1924 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
1925 in the default answer, as if the default line was a set of arguments given to a
1926 script shell.  This means you may also use $* to repeat the whole default line,
1927 so you do not have to re-type everything to add something to the default.
1928
1929 Everytime there is a substitution, you will have to confirm.  If there is an
1930 error (e.g. an unmatched backtick), the default answer will remain unchanged
1931 and you will be prompted again.
1932
1933 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
1934 the questions and use the computed defaults (or the previous answers if there
1935 was already a config.sh file). Type 'Configure -h' for a list of options.
1936 You may also start interactively and then answer '& -d' at any prompt to turn
1937 on the non-interactive behaviour for the remainder of the execution.

1943 Much effort has been expended to ensure that this shell script will run on any
1944 Unix system.  If despite that it blows up on yours, your best bet is to edit
1945 Configure and run it again.  If you can't run Configure for some reason,
1946 you'll have to generate a config.sh file by hand.  Whatever problems you
1947 have, let me (perlbug@perl.org) know how I blew it.
1948
1949 This installation script affects things in two ways:
1950
1951 1) it may do direct variable substitutions on some of the files included
1952    in this kit.
1953 2) it builds a config.h file for inclusion in C programs.  You may edit
1954    any of these files as the need arises after running this script.
1955
1956 If you make a mistake on a question, there is no easy way to back up to it
1957 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
1958 files.  Configure will offer to let you do this before it runs the SH files.

3499
3500     In general it is a good idea to keep gcc synchronized with
3501     the operating system because otherwise serious problems
3502     may ensue when trying to compile software, like Perl.
3503
3504     I'm trying to be optimistic here, though, and will continue.
3505     If later during the configuration and build icky compilation
3506     problems appear (headerfile conflicts being the most common
3507     manifestation), I suggest reinstalling the gcc to match
