I started working on extending SWIG to generate bindings for NativeBoost FFI, using as a reference the C# binding generator. I am committing my work on this into https://github.com/ronsaldo/swig/ . It works by creating a C side code and Smalltalk that can be filed-in in a image, which contains a class with all the NativeBoost-FFI callouts, a class for the global module, classes for each C++ class and SWIGTYPE_* classes for opaque types or types that SWIG couldn't wrap. It currently can generate bindings for C/C++ functions, constants, define based constants, opaque structures, methods, enums, and for C++ classes, nested classes, member methods, member fields, member constants, member static functions, variables and constants. The overloaded functions support currently is not so great, since I am currently using the arguments name to build the selector. I have to still decide a better strategy for the overloaded methods. WARNING: automatic garbage collection of the C++ classes is not yet ready, but it will be soon. Downcasting of C++ objects is also not supported yet. Greetings Ronie Salgado
