Hi,
In graph/detail/adjacency_list.hpp:2766 there is a specialization of
struct hash for void*. Isn't the generic pointer specialization in
functional/hash/extensions.hpp:172 enough?
The problem I am facing is the following (which I couldn't reproduce in
a trivial example):
1. I include and
2. I create an std::tr1::unordered_map and typedef
std::tr1::unordered_map::iterator iterator_type;
3. In some test file that includes and
uses it, I get the following error (gcc 4.4.5/4.6.1):
/usr/local/include/boost/graph/detail/adjacency_list.hpp:2766: error:
specialization of ‘boost::hash’ after instantiation
/usr/local/include/boost/graph/detail/adjacency_list.hpp:2766: error:
redefinition of ‘struct boost::hash’
/usr/local/usr/include/boost/functional/hash/extensions.hpp:172: error:
previous definition of ‘struct boost::hash’
I can resolve it by providing my own hash functor to the unordered_map
(which causes hash not to be instantiated). I will keep trying to
provide a trivial example.
Thanks
