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.)

21# Though this script was generated by metaconfig, it is OK to send
22# patches against it. It's up to the Configure pumpkin to backport
23# the patch to the metaunits if it is accepted.
24# See Porting/pumpkin.pod for more information on metaconfig.

35SCO csh still thinks true is false. Write to SCO today and tell them that next
36year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
37
38(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
39we'd have to do is go in and swap the && and || tokens, wherever they are.)

2091*** WHOA THERE!!! ***
2092
2093 This is an UNSTABLE DEVELOPMENT release.

JH
2094 The version of this $package distribution is $xversion, that is, odd,
2095 (as opposed to even) and that signifies a development release.
3d5d58b1 2096 If you want a maintenance release, you want an even-numbered version.

2098 Do ***NOT*** install this into production use.
2099 Data corruption and crashes are possible.
2100
2101 It is most seriously suggested that you do not continue any further
2102 unless you want to help in developing and debugging Perl.

2304df62 2154This installation shell script will examine your system and ask you questions
a0d0e21e 2155to determine how the perl5 package should be installed. If you get
2304df62
AD
2156stuck on a question, you may use a ! shell escape to start a subshell or
2157execute a command. Many of the questions will have default answers in square
2158brackets; typing carriage return will give you the default.
2159
2160On some of the questions which ask for file or directory names you are allowed
2161to use the ~name construct to specify the login directory belonging to "name",
2162even if you don't have a shell which knows about that. Questions where this is
2163allowed will be marked "(~name ok)".
2164
2165EOH
2166 rp=''
2167 dflt='Type carriage return to continue'
2168 . ./myread
2169 cat <<'EOH'
2170
2171The prompter used in this script allows you to use shell variables and
2172backticks in your answers. You may use $1, $2, etc... to refer to the words
2173in the default answer, as if the default line was a set of arguments given to a
2174script shell. This means you may also use $* to repeat the whole default line,
2175so you do not have to re-type everything to add something to the default.
2176
2177Everytime there is a substitution, you will have to confirm. If there is an
2178error (e.g. an unmatched backtick), the default answer will remain unchanged
2179and you will be prompted again.
2180
2181If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2182the questions and use the computed defaults (or the previous answers if there
2183was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 2184You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 2185on the non-interactive behaviour for the remainder of the execution.

2191Much effort has been expended to ensure that this shell script will run on any
2192Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
2193Configure and run it again. If you can't run Configure for some reason,
2194you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 2195have, let me (perlbug@perl.org) know how I blew it.

2196
2197This installation script affects things in two ways:
2198
21991) it may do direct variable substitutions on some of the files included
2200 in this kit.
22012) it builds a config.h file for inclusion in C programs. You may edit
2202 any of these files as the need arises after running this script.
2203
2204If you make a mistake on a question, there is no easy way to back up to it
2205currently. The easiest thing to do is to edit config.sh and rerun all the SH
2206files. Configure will offer to let you do this before it runs the SH files.

3628Note that Perl built with threading support runs slightly slower

3648Since release 5.6, Perl has had two different threading implementations,
3649the newer interpreter-based version (ithreads) with one interpreter per
3650thread, and the older 5.005 version (5005threads).
3651The 5005threads version is effectively unmaintained and will probably be
3652removed in Perl 5.10, so there should be no need to build a Perl using it
3653unless needed for backwards compatibility with some existing 5.005threads
3654code.
