with the NVHPC/PGI 21.9 compiler by using the setting
configure -*-enable-mca-no-build=op-avx* ...
We're still looking at the cause here. I don't have any advice about the
problem with 21.7.

Tried this
configure CC='nvc -fPIC' CXX='nvc++ -fPIC' FC='nvfortran -fPIC'
Configure completes. Compiles quite a way through. Dies in a different
place. It does get past the

Ray,
If all the errors about not being compiled with -fPIC are still appearing,
there may be a bug that
is preventing the option from getting through to the compiler(s). It might be
worth looking through
the logs to see the full compile command for one or more of them to see whether
that is true? Say,
libs/comm_spawn_multiple_f08.o for example?
If -fPIC is missing, you may be able to recompile that manually with the -fPIC
in place, then remake
and see if that also causes the link error to go away, that would be a good
start.
Hope this helps, -- bennet

I did try that and it fails at the same place.
Which version of the nVidia HPC-SDK are you using? I a m using 21.7. I see
there is an upgrade to
21.9, which came out since I installed. I have that installed and will
try to see if they changed
anything. Not much in the releases notes to indicate any major changes.
