I'm trying to compile a PyCUDA kernel. The compilation fails with the error:
pycuda.driver.CompileError: nvcc preprocessing of C:\Users\itay\AppData\Local\Temp\tmp78b6tln1.cu failed
[command: nvcc --preprocess -arch sm_52 -m64 -Ic:\users\itay\sources\pythonmaps\env\lib\site-packages\pycuda\cuda C:\Users\itay\AppData\Local\Temp\tmp78b6tln1.cu --compiler-options -EP]
Running the same command from a command prompt works fine.
The CompileError
exception has a strerr
attribute which contains the stderr of the compilation. It is empty. Only by placing a break-point inside PyCUDA did I find the actual error, which was reported by nvcc
to stdout.
Is there a way to get the compilation output without placing breakpoints in PyCUDA?
