I4dvar compilation error about i4dvar.f90 and mod_fourdvar

#1 Unread post by MIKESHEN »

Hello, i upgrade ROMS to the new version:
run the build_roms_4dvshc.csh file.
I have check my bash.csh .h and .mk files. Still with some trouble like this:
i4dvar.f90:319.10:

USE mod_fourdvar
1
Error: 'increment' of module 'mod_fourdvar', imported at (1), is also the name of the current program unit

Any help or suggestion will be highly appreciated.

Hi there, I encountered similar error with gfortran 9.3. However, ROMS run well with intel fortran compiler instead of gfortran.

Yes, gfortran is a stricter compiler. Other compilers relax the Fortran standard rule that we cannot have a module, subroutine, or variable with the same name. I missed this one. Thank you for reporting this issue. Please, update your code.
