Hi, I created a simple property_map as follows:
struct VecMap { typedef int value_type;
typedef int key_type; typedef read_write_property_map_tag category;
typedef int* reference; std::vector<int> vec_store;
}; void put(VecMap& rmap, int key, int val)
{ rmap.vec_store[key] = val;
} int get(VecMap& rmap, int key)
{ return rmap.vec_store[key];
} /// End code The compiler gcc-4.4.1 against latest boost-trunk gives errorerror: no type named value_type in struct boost::property_traits<VecMap> The code however compiles fine with boost_1_40. Please take a look.

I tried the code you posted (at codepad) with GCC 3.4, 4.1, and 4.4.0 and
did not receive an error. Note that in the trunk, the property_map header
file is
