Testing with OSSS OpenSHMEM, the compile process fails with

Tony, thanks for sending in a bug! Can you provide some more details on your OSS OpenSHMEM version? Is this a release version or from a specific commit?
Hi John, it's the latest commit, but it would be true for any version. -loshmem -lmpi is presumably meant to be from Open-MPI and they are explicitly linked via cmake.
$ CC=oshcc CXX=oshcxx cmake -DENABLE_OPENSHMEM=ON ..
Tony, I'll try to get a new OpenSHMEM build running and triage this.
I can do a PR if you like
I have a fix in the works that fixes the link issue and the warnings associated with mpp/shmem.h. I'm updating the documentation now...
Tony, can you confirm that commit 66a4e2c builds for you before i close the issue?
Yep, it works. That's what I did...
Thanks Tony!
