NAME
README.beos - Perl version 5.8+ on BeOS
DESCRIPTION
This file contains instructions how to build Perl under BeOS and lists
known problems.
BUILD AND INSTALL
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 "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:
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
Build
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
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.
KNOWN PROBLEMS
*
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.
