SWIG: No module name specified using %module or -module

Question

I am using SWIG to generate some language bindings to some C++ code. I am getting this warning at the console:

No module name specified using %module or -module

The warning is self explanatory, but is it something I should worry about?

Answer 1

Yes, it is something to worry about. It is an error not a warning and the generated wrapper file was not created (at least not with the SWIG 2.0.8 version I tested with). Simply add %module modulename to the top of your SWIG .i file.
