Error at bulding from source (Error: Rank mismatch in argument ‘cont’ at (1) (scalar and rank-1))

[wgb-256]

Hi,

I got an error when I tried to build Assimulo from source by Docker in order to build PyFMI finally. I guess fortran compiler was not fitted for this version. Does anyone have idea to debug? Let me know if you need any more info. Thank you!

Error:

Hi,

can you try with invoking setup.py with an additional --extra-fortran-compile-flags=-std=legacy?

@PeterMeisrimelModelon It looked going well! Thank you!

Can you guess why it worked?

[PeterMeisrimelModelon]

Glad to hear it works.

Your log shows a number of "Fortran 2018" warnings; the fortran codes used here are however legacy codes and are not kept compliant with newer versions of the Fortran standard.
