Hi Noam; I do not have gfortran, therefore I must not have gcc?
Here is a filtered list of the ports that I have installed that pertain to gcc: gcc12 @12.3.0_4+stdlib_flag (active) gcc12-libcxx @12.3.0_4+clang14 (active) gcc13 @13.2.0_4+stdlib_flag (active) gcc13-libcxx @13.2.0_4+clang16 (active) gcc_select @0.1_10 (active) libgcc @7.0_0 (active) libgcc12 @12.3.0_4+stdlib_flag (active) libgcc13 @13.2.0_4+stdlib_flag (active) mpich-default @4.1.2_2+gcc13 (active) Still confused...
