I find it unfortunate that MPICH2 configure automatically puts whatever CFLAGS it was built with into the wrappers. You have to use MPICH2LIB_CFLAGS to only use them for MPICH2. This is probably the issue with your -O2/-O3 warning. Better BLAS/Lapack detection would be worthwhile. Note that it currently accounts for almost 50% of the entire time spent in configure. It's hard for me to believe there is no faster way to do it. -------------- next part -------------- An HTML attachment was scrubbed...
