Re: [Swig-user] Changing target std::vector type

[David P. <dpi...@me...>]

%typemap(*) char doesn't work because you are wrapping vector<char>, not char. As far as typemaps are concerned, there is no relationship between the two.

This probably won't work, but (if you don't mind that EVERY vector<char> would be wrapped as a list of bytes) you could try 

SWIG_STD_VECTOR_SPECIALIZE_MINIMUM(byte, char)
%template(ByteVector) std::vector<char>;

Come to think of it, maybe the typemaps you wrote below would help make the above work, but I don't have time to experiment personally.
