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.)

40I will attempt to remedy the situation by running sh for you...

2304df62 1918This installation shell script will examine your system and ask you questions
a0d0e21e 1919to determine how the perl5 package should be installed. If you get
2304df62
AD
1920stuck on a question, you may use a ! shell escape to start a subshell or
1921execute a command. Many of the questions will have default answers in square
1922brackets; typing carriage return will give you the default.
1923
1924On some of the questions which ask for file or directory names you are allowed
1925to use the ~name construct to specify the login directory belonging to "name",
1926even if you don't have a shell which knows about that. Questions where this is
1927allowed will be marked "(~name ok)".

1932 . ./myread
1933 cat <<'EOH'
1934
1935The prompter used in this script allows you to use shell variables and
1936backticks in your answers. You may use $1, $2, etc... to refer to the words
1937in the default answer, as if the default line was a set of arguments given to a
1938script shell. This means you may also use $* to repeat the whole default line,
1939so you do not have to re-type everything to add something to the default.
1940
1941Everytime there is a substitution, you will have to confirm. If there is an
1942error (e.g. an unmatched backtick), the default answer will remain unchanged
1943and you will be prompted again.
1944
1945If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1946the questions and use the computed defaults (or the previous answers if there
1947was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1948You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1949on the non-interactive behaviour for the remainder of the execution.

1955Much effort has been expended to ensure that this shell script will run on any
1956Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1957Configure and run it again. If you can't run Configure for some reason,
1958you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 1959have, let me (perlbug@perl.org) know how I blew it.

1961This installation script affects things in two ways:
1962
19631) it may do direct variable substitutions on some of the files included
1964 in this kit.
19652) it builds a config.h file for inclusion in C programs. You may edit
1966 any of these files as the need arises after running this script.
1967
1968If you make a mistake on a question, there is no easy way to back up to it
1969currently. The easiest thing to do is to edit config.sh and rerun all the SH
1970files. Configure will offer to let you do this before it runs the SH files.

3208some known race conditions still remain. If you choose to try
3209it, be very sure to not actually deploy it for production

3228As of 5.5.640, Perl has two different internal threading implementations,
3229the 5.005 version (5005threads) and an interpreter-based version
3230(ithreads) that has one interpreter per thread. Both are very
3231experimental. This arrangement exists to help developers work out
3232which one is better.
3233
3234If you're a casual user, you probably don't want interpreter-threads
