[petsc-users] Configuring PETSc on Mac M1

[Giselle Sosa Jones]

Hello,

I am trying to install PETSc on my M1 Mac and I keep encountering the
following error when configuring:

Unknown Fortran name mangling: Are you sure the C and Fortran compilers are
compatible?

  Perhaps one is 64 bit and one is 32 bit?


Any ideas on how to fix this? All my compilers are 64 bit. I am using
gfortran and gcc (installed with brew).

Thank you in advance.
