nvcc fatal : Failed to detect host compiler properties

I'm using nvcc in a very standard way:

nvcc -ccbin g++ mycode.cu

And it's suddenly stopped working, giving the error:

nvcc fatal : Failed to detect host compiler properties

Why might this be?

Solution

  • In this case, the issue was caused by the root partition running out of memory, as verified by df -h:

    /dev/nvme0n1p2      24G   23G     0 100% /

    As a quick way to get memory back, I ran:

    sudo apt clean

    Which recovered 2.4GB.

    After this, nvcc again works without problems.
