If you build netcdf with shared libraries, configure-script will include --enable-separate-fortran option automatically. When all the fortran-functions will be in libnetcdff.a(.so). You must correct {Platform}-{compiler}.mk file with next: ... LIBS := -L{NETCDF_LIBDIR} -lnetcdff ... ie replace ...

Ok, I run app with Hwave 0.2 and he work fine with small kinetic energy. Kinetic energy fluctuates, but the tendency growing.
What can I do with SWAN, because const wave is bad way for research my region?

If I do Hwave less when 2.0 when kinetic energy becomes less and ROMS work more long.
