PERLFREEBSD(1)                        Perl Programmers Reference Guide                        PERLFREEBSD(1)



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 nonre-entrant
       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.
