Hi all,
First of all, I new to the mailing list, so please excuse me for any beginner's mistakes I may make :) I am also new to the Boost Graph Library.
I am having some trouble implementing the Boost Graph Library isomorphism algorithm under MSVC++ 2008 Express Edition. Since I am using MSVC++, I cannot use the named parameter method, as specified in the docs. I am not entirely sure, but I think my problem is the vertex invariants that I pass to the algorithm. I am using Boost 1.43.
Please try the named parameter version -- the comment about VC++ is probably about version 6, and you are using a much newer (and more compliant) version. Otherwise, the actual default used in the implementation appears to be difficult to construct. You might be able to pass "boost::constant_property_map<VertexDescriptor, int>(0)" as both of the invariant arguments (and 1 as vertex_max_invariant), but I'm not sure and haven't tried it. -- Jeremiah Willcock
