[FFmpeg-devel] Unable to compile with cuda on WSL2

[Dylan Fernando]

I'm trying to compile on WSL2 Ubuntu with cuda enabled. Command:

./configure --enable-nonfree --enable-cuda-nvcc --extra-c
flags=-I/opt/local/cuda/include --nvccflags="-gencode
arch=compute_52,code=sm_52 -O2"

when compiling, I get the error:
NVCC    libavfilter/vf_bilateral_cuda.ptx
/bin/sh: 1: nvcc: not found
make: *** [ffbuild/common.mak:128: libavfilter/vf_bilateral_cuda.ptx] Error
127

The output when I run nvcc -V is:
nvcc: NVIDIA (R) Cuda compiler driver

I added this to .bashrc:
export CUDA_HOME=/usr/local/cuda-12.1
export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-12.1/lib64:/usr/local/cuda-12.1/extras/CUPTI/lib64
export PATH=$PATH:$CUDA_HOME/bin

Thanks,
