This won't do you any good with Amber: it is using the version of
gcc/gfortran that is in your PATH variable, not anything inside
/usr/lib/nvidia-cuda/toolkit (unless that is in your PATH).
So, you should type "which gcc" (or "which gfortran") at the command prompt,
and make sure that these compilers are compatible with CUDA 10.1 (basically,
that they are version 8 or lower, and I understand it.) You may just need
to update your PATH variable to point to the correct compilers.
....good luck...dac
