Tony,
I had tried just the compile line using -O0, but it did not help. The last assembly I actually wrote was for a Cray Y-MP I think, so I don't intend on delving into that. Sorry I couldn't be more help. I do have access to what I call a Frankenstein Cluster of Itaniums ( different manufactures and different OS's) to support our clients, so I don't mind testing. Sorry I could not help, Joe ________________________________ From: users-boun...@open-mpi.org [mailto:users-boun...@open-mpi.org] On Behalf Of Iannetti, Anthony C. (GRC-RTB0) Sent: Thursday, January 29, 2009 11:22 AM To: Open MPI Users Subject: Re: [OMPI users] Joe Griffin: "Re: Cannot compile on LinuxItanium system" Joe, Intel recommends to set all of the compile flags, like CCFLAGS, to -O2. Other than than, we are doing nothing different than what Intel recommends. When I set CCAS=ias, ./configure does not make it through the Assembler stage. When I set CCAS=ias and CASFLAGS= (I am setting it to nothing), it makes it through the Assembler config stage and fails at another point in make. I will send another email with the actual errors.
