thanks for the reply, it was really helpful :) I've set FORTRANFLAGS to F90FLAGS and it is working now

best regards

hi all,
I have a bunch of Fortran files; mainly with *.f90 extension, but also few with *.for extension. during compilation, i have noticed that F90FLAGS which I've set to build environment are applied only to *.f90, but not to *.for files (which causes me problems later at link stage).


per default, the *.for extension is linked to the standard Fortran compiler (FORTRANCOM) and uses FORTRANFLAGS, not F90FLAGS.
You can set FORTRANFLAGS to the same value as F90FLAGS and should get what you want.

Another option would be to link the *.for files to the F90 compiler as well, if you're sure that you want everything with this extension to get processed with the F90* setup too. For this, you would redefine the Fortran file suffix lists as follows:

env = Environment(FORTRANFILESUFFIXES=['.f', '.ftn'],
tools= ...

I hope this helps you further.

Best regards,
