README.beos - Perl version 5.8+ on BeOS

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

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 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.

With flock() support:

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

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

Without flock() support:

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

With flock() support:

make LDLOADLIBS="-lnet -lflock"

Without flock() support:

make LDLOADLIBS="-lnet"

-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).

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 5.8.6 with your respective version of Perl.

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

• The LFS (large file support) tests (t/op/lfs and 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.

• The 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 system("perl -e 0") flushes the stdout pipe of another child process.

• The 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.

For BeOS specifics problems feel free to mail to: Ingo Weinhold <bonefish@cs.tu-berlin.de>
