Another question. What do I need to include to run the standalone executable? I have the dlls that it requests, but as it runs it says it can't find the 'dir' command I call from feval; as well as octave_base_value::map_value(): wrong type argument `<unknown type>' is reported as an error.
The executable works fine from within the Octave bin directory, but I don't know what else is needed.
