Hi gang,
I have both CUDA and PyCUDA related questions.
For CUDA, I'm using the latest drivers (195.x.x) and latest toolkit/sdk
(3.0). My problem is compiling the set of test programs. I remember in the
past that a hack had to be performed -- ie, comment out some function
declarations in cuda's math_functions.h. I've received the following error:
/usr/local/cuda/bin/../include/math_functions.h:422: error: inline function
‘int __signbit(double)’ cannot be declared weak
/usr/local/cuda/bin/../include/math_functions.h:427: error: inline function
‘int __signbitf(float)’ cannot be declared weak
/usr/local/cuda/bin/../include/math_functions.h:440: error: inline function
‘int __signbitl(long double)’ cannot be declared weak
The work around is to comment these lines out -- but is this still the best
way to go about it?
For PyCUDA, I've downloaded the latest beta (0.94.xxx). The compilation of
the wrapper for the driver goes smoothly. However, the test fails with the
following undefined symbol error. Even with the 190.xxx.xxx drivers and the
fix I mentioned above, I still get this error =\ Any one encountering
similar issues?
Traceback (most recent call last):
