How to connect ifort to a 'gfortran' lib

[Peng__Jerry]

Hi:

   sorry for the disturbing.

   Now I compile all my ocean model with the help of ifort, but I also need to use the NCL static lib which compiled by gfortran. it always said that "undefined reference to MAIN__"

   What should I do now? Thanks for your help.

Best Regards

This usually means that you compile a module as if it were a main program. Without code and compile or link command nothing else to add.

You can't do this - it won't work. In general, you must recompile all sources using a single Fortran compiler. Objects and libraries from one Fortran compiler don't work with those from another.
