Hi, Nicholas.

Can you see if this patch solves your issue?

Hi, Nicholas.

The support for the nemesis channel was deprecated. That is why this was not caught earlier. We will try to see if this can be fixed for the upcoming release.

Best,
Hari.

Unable to build MVAPICH2-2.3.4 from source code with --with-device=ch3:nemesis:tcp --disable-fortran configure flags.
This is on CentOS 7.8 with GCC 10.2.0.

fatal error: helper_fns.h: No such file or directory is occurring in all files that reference it.

Oddly enough, this file appears to be located in ./src/mpi/coll/helper_fns.h.

Using CFLAGS to add the path results in missing function definitions.
