PERLBEOS(1)


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:

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

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

  Configure

  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

  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.
