[mod_python] Dupe: Undefined symbol "PyEval_AcquireLock"

Thanks for the hints; it is strange that Makefile for python 2.4 has
these lines:

.if !defined(WITHOUT_THREADS)
CONFIGURE_ARGS+=        --with-threads

This seems to indicate that threads should be built in to the version I
have running.  Nevertheless, when I try "import threading" from within
python, I get this error:

>>> import threading
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/local/lib/python2.4/threading.py", line 6, in ?
    import thread
ImportError: No module named thread

I do not understand how to use "LIBS=-lc_r ./configure
--with-threads"..  Is it possible to enter the "LIBS=-lc_r" somewhere in
the Makefile?

Thanks again.

Andrew

My experience with FreeBSD systems is that threading wasn't builtin to
Python by default. To see if threading is builtin, from the command
line run Python and then do:

   import threading

If it fails, probably indicates Python wasn't built with threading
support in the first place. If this is the case, you will need to
rebuild Python with threading enabled. Note that on FreeBSD I believe
the POSIX thread library functions are in -lc_r, ie., reentrant
version of standard C library. Command line for configure probably
something like:

   LIBS=-lc_r ./configure --with-threads
