Wrapping a vector of vector of ints with CSharp

[baoilleach]

Is it possible to use %template to wrap a vector of vector of ints with CSharp?

I have the following in my interface file:
%include "std_vector.i"
%template (vvInt)      std::vector<std::vector<int> >;

but when I compile the resulting .cs files, I always get "alias 'std'
not found" because of lines like:
    // Type-safe iterator Current
    public std::vector<int > Current {
      get {

I haven't had any problem wrapping the simpler std::vector<int> on its
own. I've also tried preceding the %template line with:
SWIG_STD_VECTOR_SPECIALIZE_MINIMUM(vector, std::vector<init>);
...but with the same result.

Regards,
   Noel

You haven't quite got the parameters right for
SWIG_STD_VECTOR_SPECIALIZE_MINIMUM right and you need to wrap
std::vector<int> too. This works:

%include "std_vector.i"
%template (vInt)      std::vector<int>;
SWIG_STD_VECTOR_SPECIALIZE_MINIMUM(vInt, std::vector<int>)
%template (vvInt)      std::vector<std::vector<int> >;
