Thanks again Roland,

It does seem that your suspicion is correct; it appears that I do have both gcc-10 and gfortran-10 installed, and the Macports selection is being overridden. See the attached text files you requested.

Best, Mario

Hello Mario,

hmm. Odd. The error message looks like the one gfortran-10 produces.

Can you please attach, as a text file, the content of the file

configs/sim/config-info

as well as the file

configs/sim/OptionList

? There is some automatism in simfactory's setup-silent and it will *first* probe for gcc-10 and gcc-mp-10 and only of that does not exist will it use "gcc" (ie the macports select setting is effectively ignored).

Can you also please check if you have gfortran-10 installed at all (the executable is called gfortran-mp-10)?

If possible, it would be best to keep the conversation on the mailing list by using "reply-all" (I try to set reply-to but sometimes I miss it).

Yours, Roland
