Problem when debugging MATLAB CUDA mex file (2.2beta)

performing CUDA calculation
??? Invalid MEX-file ‘/home/me/matlab/prog/cuda/kernel.mexa64’:
/home/me/matlab/prog/cuda/kernel.mexa64: undefined symbol: $gpu_registers.

This line is in
CFLAGS=’-O3 -DBG=1 --ptxas-options=-v -G -g --keep -arch sm_13 -Xcompiler “-fPIC -D_GNU_SOURCE -pthread -fexceptions -m64”’

OS :
Fedora Core 10, x86_64, 2.2beta, matlab 2007b

The $gpu_registers symbol is defined in a file called, located in the /usr/local/cuda/bin directory.

It is possible that when compiling the mex file, it does not get linked properly.

Could you try to:

  1. copy the file in the same directory where you are compiling the project

  2. generate an object file from

  3. add this object to your mex file

Incredibly crappy antivirus software prevented me yesterday from trying this out and the rest of this week is holidays here so monday I will try it.
