RE: [ROOT] CINT: vector<...> as argument of a function

Hi,

Thanks for your report, this problem is not solved yet but has a very simple
work around.

You need to actually use a vector<int> before defining a function taking one
as a parameter.

For example:

// macro2.C
#include <vector>
typedef vector<int> vector_int;
#include <vector>
void myfunc(vector<int> &v)
{
  cerr<<v[0]<<endl;
}

root [0] .L macro2.C
root [1] vector<int> v;
root [2] v.push_back(3);
root [3] myfunc(v);
3
root [4] 

Philippe.
