[Boost-users] Re: boost/graph 1.32.0 : compilation errors on a SUN machine

I cannot compile the boost/graph library 1.32.0 on a SUN machine using Sun C++ 5.5. I get the following error message :

boost_1_32_0/boost/graph/depth_first_search.hpp", line 377: Error: Default arguments cannot be added in later declarations of the template function in the same scope.

which does make sense since the compiler cannot decide which routine depth_first_visit to use if the second routine (line 371) has an extra template but the the extra template has a default value.

I don't think the compiler is right. The second version should be used if - the extra function parameter is explicitly provided, or - the function is called with explicitly specified *four* template parameters In other cases, compiler won't be able to deduce template parameters for the second function, and will call the first one. I'd suggest to report a bug to Sun.

Unfortunately the compilation was afterwards not successful; this time I got

"boost_1_32_0/boost/graph/named_function_params.hpp", line 500: Error: Cannot return const boost::bgl_named_params, boost::graph_visitor_t, boost::no_property> from a function that should return boost::detail::error_property_not_found.

No idea here. The Sun compiler is not considered very standard-compliant, and guessing what is wrong here is hard. Do you pass root vertex to dfs search? If not, then the function must return error_property_not_found, and it it tries to return something else, the bug is in the 'Dispatcher' logic. - Volodya - Volodya
