Hi - I'm using "g++ (GCC) 3.4.5 20051201 (Red Hat 3.4.5-2)" I suspect I'm doing something wrong, and I'm sure this is a FAQ, but a few hours of reading and googling has not turned anything up. I'm simply trying to pass an iterator to a template function. Here is a simplified example that still has the error I'm seeing. I get (approximately) the same error with g++ 3.2.3, 3.3.6 and 3.4.5 --------------- #include <vector> template <class T> void one(typename std::vector<T>::iterator it) { (*it)++; } int main(int ac, char **av) { std::vector<int> v(10); one(v.begin()); return 0; } --------------- > g++ test.cpp test.cpp: In function `int main(int, char**)': test.cpp:12: error: no matching function for call to `one(__gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >)' Any help would be appreciated. thanks, Dan
