I have a .cu file with these heads:
#include </usr/include/features.h>
#include </usr/include/assert.h>
#include </usr/include/stdio.h>
When I use nvcc command to compile this file, it passed, but when I use cupy.RawKernel() to execute code in this .cu file, it crashed with this:
PyDev console: starting.

1 catastrophic error detected in the compilation of "/tmp/tmpjszp_wuk/239939fff8cdfee531aa36905d9ea0a21ebe8db4.cubin.cu".
Compilation terminated.
So how to quote correct head files rather than put all files in #include？
change backend parameter to 'nvcc' when use cupy.RawKernel() will solve it.
