And my PATH:

I have tried to lower my g++ version to g++-11 and g++-10, but it doesn't work.

By the way, a CUDA toolkit (including nvcc) is installed system-wide, outside the current virtual environment. The system CUDA version is 12.0, while the virtual environment uses a different CUDA runtime (11.8).The system-level nvcc is located at /usr/bin/nvcc, but the virtual environment prioritizes its own CUDA libraries. I don't know whether this may cause version conflicts during compilation since it uses subprocess.

If anyone can help, great gratitude to you!!!

Reproduce pip install /tmp/extensions/diffoctreerast with the reported Python, PyTorch, CUDA, and compiler versions. Start with the package's setup.py and the generated build output, especially the missing object files and the system versus environment CUDA paths. Done means the extension builds successfully and produces an installable wheel.
