6 README.freebsd - Perl version 5 on FreeBSD systems
7
9 This document describes various features of FreeBSD that will affect
10 how Perl version 5 (hereafter just Perl) is compiled and/or runs.
11 FreeBSD core dumps from readdir_r with ithreads
13 When perl is configured to use ithreads, it will use re-entrant library
14 calls in preference to non-re-entrant versions. There is a bug in
15 FreeBSD's "readdir_r" function in versions 4.5 and earlier that can
16 cause a SEGV when reading large directories. A patch for FreeBSD libc
17 is available (see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631
18 ) which has been integrated into FreeBSD 4.6.
19 $^X doesn't always contain a full path in FreeBSD
21 perl 5.8.0 sets $^X where possible to a full path by asking the
22 operating system. On FreeBSD the full path of the perl interpreter is
23 found by reading the symlink /proc/curproc/file. There is a bug on
24 FreeBSD, where the result of reading this symlink is can be wrong in
25 certain circumstances (see
26 http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ). In these cases
27 perl will fall back to the old behaviour of using C's argv[0] value for
28 $^X.
29 Perl will no longer be part of "base FreeBSD"
31 Not as bad as it sounds--what this means is that Perl will no longer be
32 part of the kernel build system of FreeBSD. Perl will still very
33 probably be part of the "default install", and in any case the latest
34 version will be in the ports system. The first FreeBSD version this
35 change will affect is 5.0, all 4.n versions will keep the status quo.
