| 7 | README.freebsd - Perl version 5 on FreeBSD systems |
| 8 | |
| 9 | =head1 DESCRIPTION |
| 10 | |
| 11 | This document describes various features of FreeBSD that will affect how Perl |
| 12 | version 5 (hereafter just Perl) is compiled and/or runs. |

14 | =head2 FreeBSD core dumps from readdir_r with ithreads |
| d41150a6 |
15 | |
| 16 | When perl is configured to use ithreads, it will use re-entrant library calls |
| 17 | in preference to non-re-entrant versions. There is a bug in FreeBSD's |
| 18 | C<readdir_r> function that can cause a SEGV when reading large directories. |
| 19 | A patch is available |
| 20 | (see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 ) |
| 21 | and will hopefully be integrated into FreeBSD 4.6. |
| 22 | |

23 | =head2 $^X doesn't always contain a full path in FreeBSD |
| d41150a6 |
24 | |
| 25 | perl 5.8.0 sets C<$^X> where possible to a full path by asking the operating |
| 26 | system. On FreeBSD the full path of the perl interpreter is found by reading |
| 27 | the symlink F</proc/curproc/file>. There is a bug on FreeBSD, where the |
| 28 | result of reading this symlink is can be wrong in certain circumstances |
| 29 | (see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ). |
| 30 | In these cases perl will fall back to the old behaviour of using C's |
| 31 | argv[0] value for C<$^X>. |

33 | =head2 Perl will no more be part of "base FreeBSD" |
| 34 | |
| 35 | Not as bad as it sounds--what is means is that Perl will no more be |
| 36 | part of the B<kernel build system> of FreeBSD. Perl will still very |
| 37 | probably be part of the "default install", and in any case the latest |
| 38 | version will be in the ports system. The first FreeBSD version this |
| 39 | change will affect is 5.0, all 4.n versions will keep the status quo. |
