If you read this file _as_is_, just ignore the funny characters you see. It is written in the POD format (see pod/perlpod.pod) which is specifically designed to be readable as is. =head1 NAME README.freebsd - Perl version 5 on FreeBSD systems =head1 DESCRIPTION This document describes various features of FreeBSD that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs. =head2 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 C function that can cause a SEGV when reading large directories. A patch is available (see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 ) and will hopefully be integrated into FreeBSD 4.6. =head2 $^X doesn't always contain a full path perl 5.8.0 sets C<$^X> where possible to a full path by asking the operating system. On FreeBSD the full path of the perl interpreter is found by reading the symlink F. There is a bug on FreeBSD, where the result of reading this symlink is can be wrong in certain circumstances (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 C<$^X>. =head2 Perl will no more be part of "base FreeBSD" Not as bad as it sounds--what is means is that Perl will no more be part of the B of FreeBSD. Perl will still very probably be part of the "default install", and in any case the latest version will be in the ports system. The first FreeBSD version this change will affect is 5.0, all 4.n versions will keep the status quo. =head1 AUTHOR Nicholas Clark , collating wisdom supplied by Slaven Rezic and Tim Bunce.
