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-3.0 package (which contains metaconfig) was posted in
dfe9444c
AD
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.)

29SCO csh still thinks true is false. Write to SCO today and tell them that next
30year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31
32(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33we'd have to do is go in and swap the && and || tokens, wherever they are.)

2304df62 1891This installation shell script will examine your system and ask you questions
a0d0e21e 1892to determine how the perl5 package should be installed. If you get
2304df62
AD
1893stuck on a question, you may use a ! shell escape to start a subshell or
1894execute a command. Many of the questions will have default answers in square
1895brackets; typing carriage return will give you the default.
1896
1897On some of the questions which ask for file or directory names you are allowed
1898to use the ~name construct to specify the login directory belonging to "name",
1899even if you don't have a shell which knows about that. Questions where this is
1900allowed will be marked "(~name ok)".

1905 . ./myread
1906 cat <<'EOH'
1907
1908The prompter used in this script allows you to use shell variables and
1909backticks in your answers. You may use $1, $2, etc... to refer to the words
1910in the default answer, as if the default line was a set of arguments given to a
1911script shell. This means you may also use $* to repeat the whole default line,
1912so you do not have to re-type everything to add something to the default.
1913
1914Everytime there is a substitution, you will have to confirm. If there is an
1915error (e.g. an unmatched backtick), the default answer will remain unchanged
1916and you will be prompted again.
1917
1918If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1919the questions and use the computed defaults (or the previous answers if there
1920was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1921You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1922on the non-interactive behaviour for the remainder of the execution.

1928Much effort has been expended to ensure that this shell script will run on any
1929Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1930Configure and run it again. If you can't run Configure for some reason,
1931you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 1932have, let me (perlbug@perl.org) know how I blew it.
2304df62

1933
1934This installation script affects things in two ways:
1935
19361) it may do direct variable substitutions on some of the files included
1937 in this kit.
19382) it builds a config.h file for inclusion in C programs. You may edit
1939 any of these files as the need arises after running this script.
1940
1941If you make a mistake on a question, there is no easy way to back up to it
1942currently. The easiest thing to do is to edit config.sh and rerun all the SH
1943files. Configure will offer to let you do this before it runs the SH files.

3177Perl can be built to take advantage of threads on some systems.
3178To do so, Configure can be run with -Dusethreads.

3180Note that threading is a highly experimental feature, and
3181some known race conditions still remain. If you choose to try
3182it, be very sure to not actually deploy it for production
3183purposes. README.threads has more details, and is required
3184reading if you enable threads.

3202the 5.005 version (5005threads) and an interpreter-based version
3203(ithreads) that has one interpreter per thread. Both are very
3204experimental. This arrangement exists to help developers work out
3205which one is better.
