NAME

       perllinux - 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

       perlfreebsd - Perl version 5 on FreeBSD systems

DESCRIPTION

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

   FreeBSD core dumps from readdir_r with ithreads
       When perl is configured to use ithreads, it will use re-entrant library calls in preference to non-re-entrant versions.	There is a bug in
       FreeBSD's "readdir_r" function in versions 4.5 and earlier that can cause a SEGV when reading large directories. A patch for FreeBSD libc
       is available (see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 ) which has been integrated into FreeBSD 4.6.

   $^X doesn't always contain a full path in FreeBSD
       perl sets $^X where possible to a full path by asking the operating system. On FreeBSD the full path of the perl interpreter is found by
       using "sysctl" with "KERN_PROC_PATHNAME" if that is supported, else by reading the symlink /proc/curproc/file. FreeBSD 7 and earlier has a
       bug where either approach sometimes returns an incorrect value (see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ).	In these cases
       perl will fall back to the old behaviour of using C's argv[0] value for $^X.
