While installing NVHPC/22.9 I got this error:

== FAILED: Installation ended unsuccessfully (build directory: /dev/shm/swmanage/jurecadc/NVHPC/22.9/system-system): build failed (first 300 chars): cmd "/p/software/jurecadc/stages/2023/software/NVHPC/22.9/Linux_x86_64/22.9/compilers/bin/makelocalrc -x /p/software/jurecadc/stages/2023/software/NVHPC/22.9/Linux_x86_64/22.9/compilers -g77 /" exited with exit code 1 and output:
ERROR: gfortran not found

Currently -g77 is set to /. It looks like this was copied from the PGI easyblock which the NVHPC easyblock was based on: https://github.com/easybuilders/easybuild-easyblocks/blob/develop/easybuild/easyblocks/p/pgi.py#L147 But I think it should be set to a command name:

$ $EBROOTNVHPC/Linux_x86_64/22.9/compilers/bin/makelocalrc -h | grep g77
-g77 g77     g77 command name; default is g77

to be specific, g77 and gfortran have different ways of returning some function values and they are not compatible. But on the other hand, noone should be using g77 today :-)

Would you suggest to remove -g77 / instead of changing it to -g77 gfortran?

[akesandgren]

That would be more correct yes.
