Hi,
I would like to report a possible bug with pycuda. To show the issue
I've modified demo.py adding by passing a option to the nvcc compiler:
mod = SourceModule("""
__global__ void doublify(float *a)
{
int idx = threadIdx.x + threadIdx.y*4;
a[idx] *= 2;
}
""", options=['-ccbin /usr/bin'])
However I get the following error when running demo.py:
python demo.py
*** compiler options is ['-ccbin /usr/bin', '-arch', 'sm_12',
'-I/usr/local/lib/python2.7/dist-packages/pycuda-0.94.2-py2.7-linux-x86_64.egg/pycuda/../include/pycuda']
Traceback (most recent call last):
File "demo.py", line 22, in <module>
""", options=['-ccbin /usr/bin'])
File

pycuda.driver.CompileError: nvcc compilation of /tmp/tmp4keOYP/kernel.cu
failed
[command: nvcc --cubin -ccbin /usr/bin -arch sm_12

kernel.cu]
[stderr:
nvcc fatal : Unknown option 'ccbin /usr/bin'
]
Notice that the nvcc command listed in the output is valid and will
compile the kernel correctly, yet I receiving an error from pycuda.
I would welcome any suggestions or workarounds, I'm using pycuda 0.94.2
from source with python 2.7.1+ on Ubuntu 11.04.
Thanks,
- Scott
