https://svn.boost.org/trac10/ticket/899 <pre class="wiki">I believe that I've encountered a bug in the BGL. I'm using version 103200, but I think it hasn't been reported/fixed yet. File boost/graph/detail/array_binary_tree.hpp, Lines 157 and 158 contain the following statements: edata[ boost::get(id, tmp) ] = i; edata[ boost::get(id, value()) ] = x.i; I think that the qualification should be removed. The first parameter 'id' in both calls is of type 'ID', which is a template parameter. It could be instantiated with a type defined in a different namespace, say CGAL. The global 'get()' function, which accept the CGAL id parameter is also defined in CGAL namespace. It must, because other calls to the get() function do not have the qualification, and according to ADL (Koenig Lookup), the function is searched in CGAL namespace. As a consequence the compiler (g++ &gt;= 4.1.0) complains that there is no match, and reports an error.
