Hi Marc-Andre,

Thanks for the suggestion.
I opened a ticket for this issue: http://bugs.python.org/issue4204

Thanks.

Now I understand the state of the multiprocessing module,
but it's too bad to see math, mmap and readline modules, that worked
fine before,
cannot be built anymore.

The errors you are getting appear to be related to either some
missing header files or a missing symbol definition to enable
these - looking at the ticket, you seem to have resolved all
this already :-)

As for FreeBSD4, yeah it's really dated and I understand newer FreeBSD should
make my life easier, but I would rather want Python continue to
support old system like this
as long as it's not getting very hard to maintain the clean code base.

Sure, the more platforms the better.

Thanks,

>>Hi list,

I was trying to build Python 2.6 on FreeBSD 4.11 and found it failed
to build some of the modules.

"""

Because I don't have Berkeley DB, SQLite3 tk, GDBM installed on the
system and running FreeBSD,
there is no wonder it failed to build _bsddb, _sqlite3, _tkinter,
gdbm, linuxaudiodev, spwd and sunaudiodev.

The problem is it failed to build _multiprocessing, math, mmap and readline.

Please post a bug report on python.org about these failures.

The multiprocessing module is still fairly new and obviously needs
more fine tuning for the large set of platforms on which Python
can run. However, please also note that FreeBSD4 is a rather old
version of that OS. FWIW: Python 2.6 compiles just fine on FreeBSD6.

Thanks.

Because FreeBSD is not listed on
http://www.python.org/dev/peps/pep-0011/, I suppose it's still a
supported platform.
Any help, suggestions would be appreciated.

Thanks,
