I'll just note, one can use system blas on Mac - so --download-fblaslapack is not needed. Also blacs is part of scalapack for the past many releases - so there is no more "--download-blacs" And --download-mumps implies --with-mumps=1 (same with other pkgs) - so this option is not needed [but no harm in also listing it] Satish On Fri, 15 Nov 2024, David Jiawei LUO LIANG wrote: > it works! > Thanks!!! > Try building MPICH with the additional flags: > > 'LDFLAGS=-Wl,-ld_classic -Wl,-commons,use_dylibs'
