For starters, what version is your default 'python' - just run
'python' to see - is it 2.5 or 2.6?
Make sure you installed boost with that version of Python. I suspect
the fact that you have 2 versions of Python on your system is causing
problems (it certainly has for me in the past and still occasionally
does). Be aware of the existence of both:
/Library/Frameworks/... and /System/Library/Frameworks/...

Hi,
I removed those 2 (left them blank). Re-installed but I still see
the same issue.
I noticed couple of interesting things.
I get 2 different errors whether I run the test as sudo or not:
$ python test_driver.py

Also I noticed in the boost library dir that there are 2 gcc versions:
libboost_python-xgcc40-mt-1_39.a
libboost_python-xgcc40-mt-1_39.dylib
libboost_python-xgcc40-mt.a
libboost_python-xgcc40-mt.dylib
In the siteconfig.py I used the 1_39 one. I guess I could try to
use the other one. I also have 2 version of Python 2.5 and 2.6.
However, the current one is 2.5 which is the only that worked with
Numpy.
Also my $DYLD_LIBRARY_PATH has:
/usr/local/cuda/lib:/usr/local/lib:
Thanks,
Massimo

Hi Massimo,
I'm mostly clueless about Macs, but I did notice that you built
PyCUDA for the
32-bit ABI. Maybe Boost got built against the 64-bit one?
CXXFLAGS = ['-arch','i386']
LDFLAGS = ['-arch','i386']
(Btw, my suspicion is that these shouldn't be needed because PyCUDA
(or rather
distutils) automatically picks up all the switches that were used to
build
Python, anyway.)
On Linux, similar issues are often caused by clashes with system-
wide Boost
libraries.
:-? Anyone from the Mac crowd have an idea?
