NAME
perlhurd - Perl version 5 on Hurd DESCRIPTION
If you want to use Perl on the Hurd, I recommend using the Debian GNU/Hurd distribution ( see http://www.debian.org/ ), even if an official, stable release has not yet been made. The old "gnu-0.2" binary distribution will most certainly have additional problems. Known Problems with Perl on Hurd The Perl test suite may still report some errors on the Hurd. The "lib/anydbm" and "pragma/warnings" tests will almost certainly fail. Both failures are not really specific to the Hurd, as indicated by the test suite output. The socket tests may fail if the network is not configured. You have to make "/hurd/pfinet" the translator for "/servers/socket/2", giving it the right arguments. Try "/hurd/pfinet --help" for more information. Here are the statistics for Perl 5.005_62 on my system: Failed Test Status Wstat Total Fail Failed List of failed ------------------------------------------------------------------------- lib/anydbm.t 12 1 8.33% 12 pragma/warnings 333 1 0.30% 215 8 tests and 24 subtests skipped. Failed 2/229 test scripts, 99.13% okay. 2/10850 subtests failed, 99.98% okay. There are quite a few systems out there that do worse! However, since I am running a very recent Hurd snapshot, in which a lot of bugs that were exposed by the Perl test suite have been fixed, you may encounter more failures. Likely candidates are: "op/stat", "lib/io_pipe", "lib/io_sock", "lib/io_udp" and "lib/time". In any way, if you're seeing failures beyond those mentioned in this document, please consider upgrading to the latest Hurd before reporting the failure as a bug. AUTHOR

NAME
perlirix - Perl version 5 on Irix systems DESCRIPTION
This document describes various features of Irix that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs. Building 32-bit Perl in Irix Use sh Configure -Dcc='cc -n32' to compile Perl 32-bit. Don't bother with -n32 unless you have 7.1 or later compilers (use cc -version to check). (Building 'cc -n32' is the default.) Building 64-bit Perl in Irix Use sh Configure -Dcc='cc -64' -Duse64bitint This requires require a 64-bit MIPS CPU (R8000, R10000, ...) You can also use sh Configure -Dcc='cc -64' -Duse64bitall but that makes no difference compared with the -Duse64bitint because of the "cc -64". You can also do sh Configure -Dcc='cc -n32' -Duse64bitint to use long longs for the 64-bit integer type, in case you don't have a 64-bit CPU. If you are using gcc, just sh Configure -Dcc=gcc -Duse64bitint should be enough, the Configure should automatically probe for the correct 64-bit settings. About Compiler Versions of Irix Some Irix cc versions, e.g. 7.3.1.1m (try cc -version) have been known to have issues (coredumps) when compiling perl.c. If you've used -OPT:fast_io=ON and this happens, try removing it. If that fails, or you didn't use that, then try adjusting other optimization options (-LNO, -INLINE, -O3 to -O2, etcetera). The compiler bug has been reported to SGI. (Allen Smith <easmith@beatrice.rutgers.edu>) Linker Problems in Irix If you get complaints about so_locations then search in the file hints/irix_6.sh for "lddflags" and do the suggested adjustments. (David Billinghurst <David.Billinghurst@riotinto.com.au>) Malloc in Irix Do not try to use Perl's malloc, this will lead into very mysterious errors (especially with -Duse64bitall). Building with threads in Irix Run Configure with -Duseithreads which will configure Perl with the Perl 5.8.0 "interpreter threads", see threads. For Irix 6.2 with perl threads, you have to have the following patches installed: 1404 Irix 6.2 Posix 1003.1b man pages 1645 Irix 6.2 & 6.3 POSIX header file updates 2000 Irix 6.2 Posix 1003.1b support modules 2254 Pthread library fixes 2401 6.2 all platform kernel rollup IMPORTANT: Without patch 2401, a kernel bug in Irix 6.2 will cause your machine to panic and crash when running threaded perl. Irix 6.3 and later are okay. Thanks to Hannu Napari <Hannu.Napari@hut.fi> for the IRIX pthreads patches information. Irix 5.3 While running Configure and when building, you are likely to get quite a few of these warnings: ld: The shared object /usr/lib/libm.so did not resolve any symbols. You may want to remove it from your link line. Ignore them: in IRIX 5.3 there is no way to quieten ld about this. During compilation you will see this warning from toke.c: uopt: Warning: Perl_yylex: this procedure not optimized because it exceeds size threshold; to optimize this procedure, use -Olimit option with value >= 4252. Ignore the warning. In IRIX 5.3 and with Perl 5.8.1 (Perl 5.8.0 didn't compile in IRIX 5.3) the following failures are known. Failed Test Stat Wstat Total Fail Failed List of Failed -------------------------------------------------------------------------- ../ext/List/Util/t/shuffle.t 0 139 ?? ?? % ?? ../lib/Math/Trig.t 255 65280 29 12 41.38% 24-29 ../lib/sort.t 0 138 119 72 60.50% 48-119 56 tests and 474 subtests skipped. Failed 3/811 test scripts, 99.63% okay. 78/75813 subtests failed, 99.90% okay. They are suspected to be compiler errors (at least the shuffle.t failure is known from some IRIX 6 setups) and math library errors (the Trig.t failure), but since IRIX 5 is long since end-of-lifed, further fixes for the IRIX are unlikely. If you can get gcc for 5.3, you could try that, too, since gcc in IRIX 6 is a known workaround for at least the shuffle.t and sort.t failures. AUTHOR
