Notes on Perl on the Hurd

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

The Perl testsuite may still report some errors on the Hurd.  The
`lib/anydbm.t' and `op/stat.t' tests will most certainly fail.  The
first fails because Berkeley DB 2 does not allow empty keys and the
test tries to use them anyway.  This is not really a Hurd bug.  The
same test fails on Linux with version 2.1 of the GNU C Library.  The
second failure is caused by a bug in the Hurd's filesystem servers,
that we have not been able to fix yet.  I don't think it is crucial.

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_03 on my system:

Failed Test  Status Wstat Total Fail  Failed  List of failed
-------------------------------------------------------------------------------
lib/anydbm.t                 12    1   8.33%  12
op/stat.t                    58    1   1.72%  4
5 tests skipped, plus 14 subtests skipped.
Failed 2/189 test scripts, 98.94% okay. 2/6669 subtests failed, 99.97% 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 testsuite have been fixed, you may
encounter more failures.  Likely candidates are: `lib/io_pipe.t',
`lib/io_sock.t', `lib/io_udp.t' and `lib/time.t'.
