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/ 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:

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 \

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/ .

Replace 5.8.6 with your respective version of Perl.
