=head1 NAME

perlbeos - Perl version 5.8+ on BeOS

=head1 DESCRIPTION

This file contains instructions how to build Perl under BeOS and lists
known problems.

=head1 BUILD AND INSTALL

=head2 Requirements

I have built and tested Perl 5.8.6 and 5.9.1 under BeOS R5 x86 net server.
I can't say anything with regard to PPC. Since Perl 5.8.0 had been released
for BeOS BONE, I suspect, there is a good chance, that it still compiles on
a BONE system. The only change I've made, that affects BONE systems is the
recognition of whether it is a BONE system or not in F<hints/beos.sh>. Now
network socket support should remain enabled on BONE systems. This might
as well break the build, though.

As more recent versions of autoconf require flock() support, I wrote a flock()
emulation (flock_server) and released it on BeBits:

http://www.bebits.com/app/4030

If you want to build a Perl with flock() support, you have to install this
package first.

=head2 Configure

With flock() support:

CFLAGS=-I/path/to/flock/server/headers ./configure.gnu \
		--prefix=/boot/home/config

Replace C</path/to/flock/server/headers> with the path to the directory
containing the C<flock.h> header.

Without flock() support:

./configure.gnu --prefix=/boot/home/config

=head2 Build

With flock() support:

make LDLOADLIBS="-lnet -lflock"

Without flock() support:

make LDLOADLIBS="-lnet"

C<-lnet> is needed on net server systems only and if the compiler doesn't
add it automatically (Be's R5 gcc does, Oliver Tappe's gcc 2.95.3 does not).

=head2 Install

Install all perl files:

make install

Create a symlink for libperl:

cd ~/config/lib; ln -s perl5/5.8.6/BePC-beos/CORE/libperl.so .

Replace C<5.8.6> with your respective version of Perl.

=head1 KNOWN PROBLEMS

=over 4

=item *

Network socket support is disabled for BeOS R5 net server. I didn't dare yet
to try enabling it and see what problems occur.

=item *

The LFS (large file support) tests (F<t/op/lfs> and F<xt/Fcntl/t/syslfs>) are
disabled as seeking beyond 2 GB is broken according to jhi@iki.fi who was the
last one checking the BeOS port and updating this file before me. Haven't
checked this myself.

=item *

The F<t/io/fflush> test fails at #6. As far as I can tell, this is caused by
a bug in the BeOS pipes implementation that occurs when starting other child
processes. In the particular test case a C<system("perl -e 0")> flushes the
stdout pipe of another child process.

=item *

The F<ext/POSIX/t/waitpid> test fails at #1. After all child processes are
gone BeOS' waitpid(-1,...) returns 0 instead of -1 (as it should). No idea
how to fix this.
