Just after copying a bunch of Python stuff, the build fails with the following message: 2023-04-23 10:42:07,023 root INFO x86_64-pc-linux-gnu-gcc -shared -flto=auto -O3 -pipe -march=native -fomit-frame-pointer -fopt-info-vec -fcf-protection=return -flto=auto -ffat-lto-objects build/temp.linux-x86_64-cpython-310/torch/csrc/stub_with_flatbuffer.o -Llib -L/usr/lib64 -L/usr/lib64 -ltorch_python -o build/lib.linux-x86_64-cpython-310/torch/_C_flatbuffer.cpython-310-x86_64-linux-gnu.so -g -Wl,-rpath,$ORIGIN/lib 2023-04-23 10:42:07,074 root INFO building 'nvfuser._C' extension 2023-04-23 10:42:07,074 root INFO x86_64-pc-linux-gnu-gcc -shared -flto=auto -O3 -pipe -march=native -fomit-frame-pointer -fopt-info-vec -fcf-protection=return -flto=auto -ffat-lto-objects -L/usr/lib64 -o build/lib.linux-x86_64-cpython-310/nvfuser/_C.cpython-310-x86_64-linux-gnu.so x86_64-pc-linux-gnu-gcc: fatal error: no input files compilation terminated. error: command '/usr/bin/x86_64-pc-linux-gnu-gcc' failed with exit code 1 Full log attached. Seems related to having USE="cuda" as on a machine with an AMD GPU (no "cuda" USE flag set) I do not see that failure.

The configuration of caffe2 is taken from /var/lib/caffe2/ and for bug report to pytorch is good to have. I guess that in this case the NVFUSER build was enabled by default, just by selecting cuda I'm going to disable explicity nvfuser, until some poor guy take care of the cuda part of pytorch.
