[petsc-users] [3.7.5] strange config error on macOS with XCode 8.3 and Clang 8.1.0

Tue Mar 28 15:12:45 CDT 2017

Dear all,

Yesterday I updated to the latest XCode and now have problems configuring PETSc (see below).
I must say that a number of other packages which need MPI fortran wrappers compiled fine.

Regards,
Denis.
