I opened a case with pgroup support regarding this.
We are also using Slurm along with HCOLL.

Thanks Jeff for the information and sharing the pointer.
FWIW, this issue typically occurs when libtool pulls the -pthread flag
from libhcoll.la that was compiled with a GNU compiler.
The simplest workaround is to remove libhcoll.la (so libtool simply
links with libhcoll.so and does not pull any c
To be more strictly equivalent, you will want to add -D_REENTRANT to add to
the substitution, but this may not affect hcoll.

The proper fix here is a change in OMPI build system, of course, to
PGI needs this in its, for instance, siterc or localrc:
# replace unknown switch -pthread with -lpthread
switch -pthread is replace(-lpthread) positional(linker);
