It should be like this:
#ifndef FC_HEADER_INCLUDED #define FC_HEADER_INCLUDED /* Mangling for Fortran global symbols without underscores. */ #define FC_GLOBAL(name,NAME) name##_ /* Mangling for Fortran global symbols with underscores. */ #define FC_GLOBAL_(name,NAME) name##_ /* Mangling for Fortran module symbols without underscores. */ #define FC_MODULE(mod_name,name, mod_NAME,NAME) __##mod_name##_MOD_##name /* Mangling for Fortran module symbols with underscores. */ #define FC_MODULE_(mod_name,name, mod_NAME,NAME) __##mod_name##_MOD_##name /*--------------------------------------------------------------------------*/ /* Mangle some symbols automatically. */ #define FC_hopping FC_GLOBAL(hopping, HOPPING) #endif Note the last define.
