Hello, Also, are the bundled properties for subgraphes implemented yet in CVS ? Yes, as of about 2 minutes ago :) Please tell me if you run into any problems. Actually, yes, I ran into a problem using the CVS. I don't think it is related to subgraph and/or bundled properties, though, but I am not sure as this seems to be something that is really a deep implementation problem. Here is the error: CourierIn file included from /Users/elvanor/Library/include/boost/type_traits/extent.hpp:14, from /Users/elvanor/Library/include/boost/type_traits.hpp:61, from /Users/elvanor/Library/include/boost/detail/numeric_traits.hpp:64, from /Users/elvanor/Library/include/boost/iterator/counting_iterator.hpp:9, from /Users/elvanor/Library/include/boost/pending/integer_range.hpp:14, from /Users/elvanor/Library/include/boost/graph/detail/adjacency_list.hpp:18, from /Users/elvanor/Library/include/boost/graph/adjacency_list.hpp:281, from /Users/elvanor/Development/probabilisticgraphicalmodels/src/GraphAlgorithms.h:4, from /Users/elvanor/Development/probabilisticgraphicalmodels/src/GraphAlgorithms.cc:7: /Users/elvanor/Library/include/boost/type_traits/detail/size_t_trait_def.hpp:33:1: "BOOST_TT_AUX_SIZE_T_TRAIT_DEF1" redefined In file included from /Users/elvanor/Library/include/boost/type_traits/rank.hpp:14, from /Users/elvanor/Library/include/boost/type_traits.hpp:60, from /Users/elvanor/Library/include/boost/detail/numeric_traits.hpp:64, from /Users/elvanor/Library/include/boost/iterator/counting_iterator.hpp:9, from /Users/elvanor/Library/include/boost/pending/integer_range.hpp:14, from /Users/elvanor/Library/include/boost/graph/detail/adjacency_list.hpp:18, from /Users/elvanor/Library/include/boost/graph/adjacency_list.hpp:281, from /Users/elvanor/Development/probabilisticgraphicalmodels/src/GraphAlgorithms.h:4, from /Users/elvanor/Development/probabilisticgraphicalmodels/src/GraphAlgorithms.cc:7: /Users/elvanor/Library/include/boost/type_traits/detail/size_t_trait_def.hpp:33:1: this is the location of the previous definition As I am unsure of how I should/could fix that, can you tell me when a fix will be provided ? (hopefully shortly because this seems to be a showstopper). Thanks Elvanor (ps: I guess I have to get used to these errors, now that I have been forced to upgrade to CVS...) ps2: as a sidenote, there doesn't seem to be any triangulation algorithm implemented for BGL... Is that hard to implement? This really seems to be missing...
