I know Open MPI dropped support for the SPARC V8 ABI some time ago. So, I configured with CC="gcc -mv8plus", but I still get:
checking if have Sparc v8+/v9 support... no configure: WARNING: Sparc v8 target is not supported in this release of Open MPI. configure: WARNING: You must specify the target architecture v8plus configure: WARNING: (cc: -xarch=v8plus, gcc: -mcpu=v9) for CFLAGS, CXXFLAGS, configure: WARNING: FFLAGS, and FCFLAGS to compile Open MPI in 32 bit mode on configure: WARNING: Sparc processors configure: error: Can not continue. So, I am wondering if there is something flawed in the "have Sparc v8+/v9 support" or if gcc's "-mv8plus" is flawed. Of course, I will follow the advise in the warning and use -mcpu=v9 instead of -mv8plus, but don't see why the later didn't work. Any ideas what is going on? And since this was found in 1.7.4rc2: WOULD SOMEBODY PLEASE REMOVE "FFLAGS" FROM THAT MESSAGE!! -Paul -- Paul H.
