       README.linux - Perl version 5 on Linux systems

DESCRIPTION

       This document describes various features of Linux that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.

   Experimental Support for Sun Studio Compilers for Linux OS
       Sun Microsystems has released a port of their Sun Studio compilers for Linux.  As of November 2005, only an alpha version has been
       released.  Until a release of these compilers is made, support for compiling Perl with these compiler experimental.

       Also, some special instructions for building Perl with Sun Studio on Linux.  Following the normal "Configure", you have to run make as
       follows:

	   LDLOADLIBS=-lc make

       "LDLOADLIBS" is an environment variable used by the linker to link modules "/ext" modules to glibc.  Currently, that environment variable
       is not getting populated by a combination of "Config" entries and "ExtUtil::MakeMaker".	While there may be a bug somewhere in Perl's
       configuration or "ExtUtil::MakeMaker" causing the problem, the most likely cause is an incomplete understanding of Sun Studio by this
       author.	Further investigation is needed to get this working better.

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

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

       o   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.

       o   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.

       o   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.
