A mesh is always linked to an Object. After all, an Object has all kind
of nice attributes which are general across most of the other object
types within blender including Mesh.
The shareFrom function needs to have an object of type Object as the
argument. So, you shouldn't pass the objSrc to shareFrom, but the
generic Object linked to the Mesh.

Well, mymesh is not initialised in your script yet, so it doesn't know
you would like it to be a blender Object. Since the shareFrom method is
only applicable to the blender Object type, you get the above error.

I hope this helps.
