Call Fortran function from .dll/.so

Hi everyone,

I want (again) to call a Fortran function from C++. Now I know how to do this when I have the source or object file, but I think that it should be possible to do this directly with the .so or .dll ?

Also, does anyone know a program which lists functions in a .so file, like one can read the exported functions in a .dll file? http://www.nirsoft.net/utils/dll_export_viewer.html

Thanks a lot in advance!

I don't know about 'nix, but from windows you use the API calls 'LoadLibrary' and 'GetProcAddress', eg:

Code:

---

typedef int ( * foo_function )( double );
HMODULE
      library = LoadLibrary( "foo.dll" );
if( library )
{
      foo_function
            function = foo_function( GetProcAddress( library, "baz" ) );           
      if( function )
      {
            int
                  result = function( 2.0 );
      }
      FreeLibrary( library );       
}

Static objects you *usually* get the imported symbols loaded in during compile time.
