Hi Danyang, I had trouble configuring PETSc on MacOS Monterey with ifort when using mpich (which I was building myself). I tracked it down to an errant "-Wl,-flat_namespace” option in the mpif90 wrapper. I rebuilt mpich with the "--enable-two-level-namespace” configuration option and the problem went away. I don’t know if there’s a similar issue with openmpi but you could check the corresponding mpif90 wrapper (mpif90 -show) whether "-Wl,-flat_namespace” is present or not. If so, perhaps passing "--enable-two-level-namespace” to PETSc configure might fix the problem (although I don’t know how you would set this flag *just* for building openmpi).
