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

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

29 SCO csh still thinks true is false. Write to SCO today and tell them that next
30 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
32 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33 we'd have to do is go in and swap the && and || tokens, wherever they are.)

1845 The version of this $package distribution is $xversion, that is, odd,
1846 (as opposed to even) and that signifies a development release.
1847 If you want a maintenance release, you want an even-numbered version.
1849 Do ***NOT*** install this into production use.
1850 Data corruption and crashes are possible.
1852 It is most seriously suggested that you do not continue any further
1853 unless you want to help in developing and debugging Perl.
1855 If you *still* want to build perl, you can answer 'y' now,
1856 or pass -Dusedevel to Configure.

1905 This installation shell script will examine your system and ask you questions
1906 to determine how the perl5 package should be installed. If you get
1907 stuck on a question, you may use a ! shell escape to start a subshell or
1908 execute a command. Many of the questions will have default answers in square
1909 brackets; typing carriage return will give you the default.
1911 On some of the questions which ask for file or directory names you are allowed
1912 to use the ~name construct to specify the login directory belonging to "name",
1913 even if you don't have a shell which knows about that. Questions where this is
1914 allowed will be marked "(~name ok)".
1918 dflt='Type carriage return to continue'
1922 The prompter used in this script allows you to use shell variables and
1923 backticks in your answers. You may use $1, $2, etc... to refer to the words
1924 in the default answer, as if the default line was a set of arguments given to a
1925 script shell. This means you may also use $* to repeat the whole default line,
1926 so you do not have to re-type everything to add something to the default.
1928 Everytime there is a substitution, you will have to confirm. If there is an
1929 error (e.g. an unmatched backtick), the default answer will remain unchanged
1930 and you will be prompted again.
1932 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1933 the questions and use the computed defaults (or the previous answers if there
1934 was already a config.sh file). Type 'Configure -h' for a list of options.
1935 You may also start interactively and then answer '& -d' at any prompt to turn
1936 on the non-interactive behaviour for the remainder of the execution.
1942 Much effort has been expended to ensure that this shell script will run on any
1943 Unix system. If despite that it blows up on yours, your best bet is to edit
1944 Configure and run it again. If you can't run Configure for some reason,
1945 you'll have to generate a config.sh file by hand. Whatever problems you
1946 have, let me (perlbug@perl.org) know how I blew it.
1948 This installation script affects things in two ways:
1950 1) it may do direct variable substitutions on some of the files included
1952 2) it builds a config.h file for inclusion in C programs. You may edit
1953 any of these files as the need arises after running this script.
1955 If you make a mistake on a question, there is no easy way to back up to it
1956 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1957 files. Configure will offer to let you do this before it runs the SH files.

5256 I can use $nm to extract the symbols from your C libraries. This
5257 is a time consuming task which may generate huge output on the disk (up
5258 to 3 megabytes) but that should make the symbols extraction faster. The
5259 alternative is to skip the 'nm' extraction part and to compile a small
5260 test program instead to determine whether each symbol is present. If
5261 you have a fast C compiler and/or if your 'nm' output cannot be parsed,
5262 this may be the best solution.
