Hi,
I have a question about purging. After filtering out certain vertices using set_vertex_filter, I want to remove all filter vertices. However, after removing them by calling the purge_vertices function, the property maps for the vertices doesn't seem to line up anymore. For example:
Initial Graph: with vertex and property map
Vertex Property Map V1: 1 Filtered V2: 2 Filtered V3: 3 Not Filtered V4: 4 Not Filtered
After calling purge I see
Vertex Property Map V3: 1 V4: 2
This is not correct because V3's mapping is 3 and not 1. Is there a simple fix to this issue or a suitable workaround without having to go back and relabel all the property maps. Thanks.

Indeed, I had not noticed this problem with purging. I've fixed this now in the git version.
Thanks for pointing this out.
Cheers, Tiago
I have gotten the updated code and compiled it. However, I'm getting an error with the src in the file graph_properties.cc

Strange, my GCC version (4.6) does not complain... But this should be fixed now, anyway.
Cheers, Tiago
