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. AUTHOR

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. AUTHOR
