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.
