Hi, Not sure how much interest is in leda wrapper of BGL. But the new version of leda broke the leda wrapper. I have made some quick fixes. However i got stuck at this error: boost_1_36_0/boost/concept_check.hpp:91: error: request for member 'error_type_must_be_a_signed_integer_type' in '((boost::SignedInteger<leda::edge_struct* const*>*)this)->boost::SignedInteger<leda::edge_struct* const*>::x', which is of non-class type 'leda::edge_struct* const*' Hopefully its the last one. After this technically the wrapper should compile. I have briefly tested it with connecte components routines. If there is interest i will happy to post the changes.. thanks sandeep
