So, here's try #2 at making property_traits usable for SFINAE (untested).
I did some little fixes to this (patch to trunk version of property_map.hpp attached) and it again passes the graph, graph_parallel, and property_map test cases. Could you please try it again with the variant bug cases?
The following tests both compile after I updated two_bit_color_map.hpp to use SFINAE on property_traits.
#include <boost/graph/two_bit_color_map.hpp> #include <boost/variant.hpp>
int test1() { using namespace boost; boost::variant<int, char> v; int i = get<int>(v); }
// make sure that it works even with incomplete types struct S;
typedef boost::variant<boost::recursive_wrapper<S> > v_type;
void test2(v_type& v) { boost::get<S>(&v); }
Could you please also test the include_test.cpp that got this thread started? If that passes I'll commit the change and see if the regression tests break (since there might be compiler compatibility issues). Thank you. -- Jeremiah Willcock
