The log tell me that ": fatal error: /usr/local/cuda/bin/../targets/x86_64-linux/include/stdc-predef.h: permission denied." `sudo cmake . -B build -DCMAKE_CUDA_COMPILER=/usr/local/cuda-11.3/bin/nvcc [sudo] ycf 的密码： -- The CUDA compiler identification is unknown -- Check for working CUDA compiler: /usr/local/cuda-11.3/bin/nvcc CMake Error in /home/ycf/tiny-cuda-nn/build/CMakeFiles/CMakeTmp/CMakeLists.txt: CUDA_ARCHITECTURES is empty for target "cmTC_069f6".

Did you add --recursive flag when cloning the repo?

This works for me.

cmake . -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo -D CMAKE_CUDA_COMPILER='/usr/local/cuda/bin/nvcc"
