Error: set() does not equal {'-lnvcpumath', '-lnvhpcatm'}

ping @leclairm @mjaehn because this is a major blocker atm.

As I see it, it's only an issue on Daint, right? If yes, that would speak for freezing the Daint config and only moving to 21.x on Alps.

So after a lot of printouts, I have a start of an answer to what is happening and what looks like a workaround

My 2 cents on what happens

in the reorder_flags method, this statement node = SpecBuilder.make_node(pkg=spec.name) generates a node that seem to only consider the package name and not the rest of the spec, e.g. the compiler. In our case, it leads to including nvhpc flags provided by compilers.yaml when trying to reorder flags for cmake%gcc and gmake%gcc.

Workarounds

2 things have worked so far:

• explicitly include ^gmake%gcc ^cmake%gcc in the spec, like spack spec [email protected]%nvhpc ^[email protected]%gcc ^[email protected] ^gmake%gcc ^cmake%gcc
• make the package depend on gmake%gcc and cmake%gcc. So directly include depends_on('gmake %gcc') and depends_on('cmake %gcc') in /repos/c2sm/packages/pytorch-fortran-proxy/package.py

Well I was wrong for what might be happening there. I think it's more in these lines:

sorted_sources = sorted(
    self._flag_sources[source_key], key=lambda s: order.index(s)
)
