[Trilinos-Users] Missing Epetra_MpiSmpComm.h header file

  I mispoke there. I assumed since 10.8.5 worked for you that the
Epetra_MpiSmpComm.h file was there. I just checked and it is not in the
10.8.5 tarball either. I've also found that it is being excluded on purpose
and has been for a while now. The actual issue is that the header in
question was pulled in to address another bug, but it turns out it wasn't
needed. Unfortunately that header didn't get removed before the release.
Mark Hoemmen has created a fix for it and is currently testing it. We should
have a bug fix release addressing this in the near future. In the mean time
a work around would be to remove the #include "Epetra_MpiSmpComm.h" from

Again, sorry for the inconvenience this has caused you.

Thanks for your patience with this,
