Silence Eigen related warnings with NVHPC? #2594

Open pramodk opened 1 year ago

pramodk commented 1 year ago

While building NEURON with NVHPC compiler, I see lots of warnings like:

@alkino : As we do with other NVHPC warnings here, we may need to silent this one as well?

There are also FMT related ones now:

@alkino : you can install NVHPC from the system package manager.

Eigen is silenced by #3132
