Hello, We use gcc 3.4 and 4.0 to compile our project OpenMS, which is based on boost. boost/graph/detail/array_binary_tree.hpp causes the following errors: ---------------------------------------------------- ../boost/graph/detail/array_binary_tree.hpp:157: error: no matching function for call to 'get(OpenMS::IteratorOffset<__gnu_cxx::__normal_iterator > >&, __gnu_cxx::__normal_iterator >&)' .../boost/graph/detail/array_binary_tree.hpp:158: error: no matching function for call to 'get(OpenMS::IteratorOffset<__gnu_cxx::__normal_iterator > >&, __gnu_cxx::__normal_iterator >&)' ---------------------------------------------------- This can be fixed by replacing the original lines: 157: edata[ boost::get(id, tmp) ] = i; 158: edata[ boost::get(id, value()) ] = x.i; by: 157: edata[ get(id, tmp) ] = i; 158: edata[ get(id, value()) ] = x.i; Is this a bug, or are we doing something wrong?
