Hi, I have been trying to build the example BOOST_ROOT/libs/graph/example/ospf-example.cpp I notice that the read_graphviz function has changed and there is no longer a function of the form in this example. I have tried to read the file using an example I found elsewhere but then I get into issues with copying the properties. Can anybody point me at a version of this example that builds with the 1.43.0 boost_graph library. Currently I get an error saying there is no matching function for read_graphviz, as expected, but I'm not having any luck reading the file with the new function prototype either. Thanks for any help, Adam. -- Dr Adam Spargo High Performance Assembly Group email: aws@sanger.ac.uk Wellcome Trust Sanger Institute Tel: +44 (0)1223 834244 x7728 Hinxton, Cambridge CB10 1SA Fax: +44 (0)1223 494919 -- The Wellcome Trust Sanger Institute is operated by Genome Research Limited, a charity registered in England with number 1021457 and a company registered in England with number 2742969, whose registered office is 215 Euston Road, London, NW1 2BE.
