Hi,

I got some problems trying to compile a topological sort code.
I created my graph with the color properties but I got the error:

error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'boost::detail::error_property_not_found' (or there is no acceptable conversion)

So, I tried the example at boost_1_46_1\libs\graph\example\topo_sort.cpp.
It works fine, but with a little change I could reproduce the error.
I change the following code at line 43:

typedef adjacency_list<vecS, vecS, directedS,
    property<vertex_color_t, default_color_type> > Graph;

to

typedef adjacency_list<vecS, listS, directedS,
    property<vertex_color_t, default_color_type> > Graph;

Should the vertex list selector influence on that?
I tried Boost 1.46.1 and got the error with both compilers:
Microsot Visual Studio 2008 version 9.0.21022.8 RTM
and
Intel® C++ Compiler Version 11.1.850.2008

I attached the modified version of the file.

With Kind Regards,
Bruno
