The code is at http://pastebin.com/m19513d00 Its very simple, i have reduced it to just the basics. but you also need an input graph - its only 2 vertices and one edge. http://pastebin.com/m4d28f922 I also included makefile , its just g++ -O3 copy-bug.cpp -o copy-bug -I/usr/local/include -L/usr/local/lib -lexpat graphml.o Thats all. --- On Tue, 8/11/09, Andrew Sutton wrote: From: Andrew Sutton Subject: Re: [Boost-users] [BGL] Can't correctly copy data To: boost-users@lists.boost.org Date: Tuesday, August 11, 2009, 4:55 AM I've been working on this bug for a few weeks now. Its sort of a show stopper for me. I'm not able to correctly copy a simple string datum from one element to another such element. Just go to  I don't see any code in link, and I'm not motivated enough to follow all of the links to reassemble and debug a program. Why don't you try reducing the problem to the smallest possible example that causes the problem and post that.  Andrew Sutton andrew.n.sutton@gmail.com -----Inline Attachment Follows----- _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

This was my error typedef typename property_map < Graph, edge_Weight_t >::type EdgeWeightMap;                 EdgeWeightMap eWeight_map, eWeightCopy_map; I needed separate types for each map as below.  typedef typename property_map < Graph, edge_Weight_t >::type EdgeWeightMap;                 EdgeWeightMap eWeight_map;                 typedef typename property_map < Graph, edge_WeightCopy_t >::type EdgeWeightCopyMap;  EdgeWeightCopyMap eWeightCopy_map; AStorm gave me the answer on the boost IRC chat. I don't know if I would have ever figured it out for myself, It seems a little tricky for noobies.
