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.


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 [AT] 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.
