- =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 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
- C<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.
-
- =head2 $^X doesn't always contain a full path in FreeBSD
-
- perl 5.8.0 sets C<$^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</proc/curproc/file>. 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 longer be part of "base FreeBSD"
-
- Not as bad as it sounds--what this means is that Perl will no longer be
- part of the B<kernel build system> 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.
