Hi Steve, Rather than using compiler flags related to underscores, I recommend following the steps here, which work with many compiler combinations without messing with underscores in function names: http://www.unidata.ucar.edu/netcdf/docs/netcdf-fortran-install.html The instructions above explain when LD_LIBRARY_PATH may be required in addition to LD_FLAGS and CPPFLAGS settings. If this doesn't work for you, we might be able to provide more help if you send the config.log file generated by the configure script when you start building the netCDF Fortran API from source. Also, it would be better to use the most recent netCDF C release, version 18.104.22.168, with netCDF Fortran 4.2. It has various bug fixes and other improvements since netCDF C 4.2 was released, and it's compatible with netCDF-Fortran version 4.2. --Russ > I have successfully cross-compiled netcdf C 4.2, i.e., build it on a x86_64 > linux box to run on a android ARM. > > Now I'm trying to cross-compile netcdf fortran 4.2.
