I'm trying to write cude code and generate a mex file. For debugging purposes, I want to print something in a cuda kernel. When I call "printf", the compiler returns the following error:
Error calling a __host__ function("mexPrintf_800") from a __global__ function("mulImg_FTot") is not allowed pendulum_propagate D:\C++\test_VS\pendulum_propagate\pendulum_propagate\integrate.cu 73
Error identifier "mexPrintf_800" is undefined in device code pendulum_propagate D:\C++\test_VS\pendulum_propagate\pendulum_propagate\integrate.cu 73

So, is there a way to print in cuda kernel when writing mex files? Thanks in advance.
