Re: [Swig-user] making std::map<std::string, std::string> visible to python?

[Ratko J. <rja...@gm...>]

Well, I have no idea what that means. A little bit of code should help (.i,
.h and .cpp).
I am just a beginner in this as well and I got maps wrapped like this with
success. What version of swig are you using? I was using the latest one...
