Whenever I do

typedef std::vector< SomeType >::iterator

I get the error:

error: wrong number of template arguments (1, should be 5)

Why is this? Is it possible to typedef a c++ vector or a vector iterator?

this works fine:

typedef std::vector<std::string> string_vector;
typedef string_vector::iterator str_vect_itr;

I would look at your typedefs carefully…
