Just out of curiosity. Is binding with Fortran not considered or not feasible or just too much effort?

The only time I have seen Fortran code is when dealing with nasa orbital simulation stuff. I think Fortran is pretty rare and experience with it is rare too. If it can export c calling convention and be compiled into a dynamic link library then anything is possible?

I never tried to bind Fortran libraries to Nim, but I often have to deal with Fortran codes in my job. If you are lucky enough to work with Fortran 2003 or 2008, you can use iso_c_binding:

I think that the most useful example in that page is the one in Sect. 9 («Example of C calling Fortran»).

It doesn't seem too hard: https://www.hoffman2.idre.ucla.edu/c-fortran-interop/

I use some Fortran bindings to the LAPACK library in neo. Here I make use of a fortran macro that abstracts for me the task of passing everything by address etc.
