Hello, I cannot compile the components_on_edgelist.cpp example with gcc 4.5/4.2 and VC++2009. I am using Boost 1.42 It trows errors on

...

c:\boost\include\boost-1_42\boost\graph\incremental_components.hpp(178) : error C2825: 'ParentIterator': must be a class or namespace when followed by '::' 1> c:\boost\include\boost-1_42\boost\graph\incremental_components.hpp(141) : see reference to function template instantiation 'void boost::component_index<IndexType>::build_index_lists(ParentIterator,const ElementIndexMap &)' being compiled 1> with 1> [ 1> IndexType=int, 1> ParentIterator=const unsigned int *, 1> T=size_t, 1> ElementIndexMap=boost::typed_identity_property_map 1> ] and more...

Are there some work around ? Actually I would like to construct disjoint sets based on vector<Edge>, where Edge is pair. Thanks Arman. -- View this message in context: http://old.nabble.com/BGL%3A-Problem-to-compile-components_on_edgelist.cpp-e... Sent from the Boost - Users mailing list archive at Nabble.com.

I fixed the various issues you are probably seeing with that example in the trunk just now; that version should work better. See if your code works with the new version. -- Jeremiah Willcock

I got the recent revision 61803. The compilation is ok but the code is crashing on the line: 72 incremental_components(g, ds); ------------- SNIP -------------------- libs/graph/example% ./components_on_edgelist.x An undirected graph (edge list): (0,1) (1,4) (4,0) (2,5) Segmentation fault ------------END SNIP------------------ SO, what is the reason?

I thought all of the array overruns were fixed -- I guess they might not have been. See if your symptoms are anything like what is in https://svn.boost.org/trac/boost/ticket/3250; if you can run valgrind, please see what it outputs. -- Jeremiah Willcock

Thanks for pointing it. The incremental_components is still broken. The bug is not fixed yet.

Do you have a complete source file I can try out to reproduce this? -- Jeremiah Willcock

I took the code from boost-trunk/libs/graph/example/components_on_edgelist.cpp compiled with g++ components_on_edgelist.cpp -I/work2/arm2arm/SOFTWARE/BOOST-SVN/include/ -o components_on_edgelist.x and valgrind components_on_edgelist.x i did not change the components_on_edgelist.cpp file from svn.

Update now -- I think I fixed it. The disjoint_sets structure was being created with a zero-length vector, and I changed it to use the number of vertices in the graph. -- Jeremiah Willcock
