Hello,

I have installed Mathematica (v5.2) on FreeBSD 5-stable.  All works
fine.  I am now trying to get the Python bindings to MathLink to
work.  I can build ok but it links against the Mathematica library (ML)
which is linux.  When I import mathlink I get undefined symbol "stdout"
message (stdout used in libML).  In FreeBSD this symbol appears to be
__stdoutp.

ldd /usr/local/lib/python2.4/site-packages/mathlink.so
/usr/local/lib/python2.4/site-packages/mathlink.so:
        libm.so.3 => /lib/libm.so.3 (0x481b6000)

If I modify setup.py to specify libm as libm-2.3.2 (the linux one)
ldd /usr/local/lib/python2.4/site-packages/mathlink.so
/usr/local/lib/python2.4/site-packages/mathlink.so:
        libm.so.6 => /compat/linux/lib/libm.so.6 (0x481b6000)
        libc.so.6 => /compat/linux/lib/libc.so.6 (0x481d7000)
        ld-linux.so.2 (0x48302000)

Then import fails with segmentation violation.

Is there any way around this or is it a hopeless cause?
(I could build a linux version of python on my system
and then it shoudl work but that is not ideal)

thanks
