[Boost-users] graph compile error with gcc3.3 when edge container is slist

3 Jan 2006

      Hi,

the attached source code is copied from 
boost_1_33_0/libs/graph/example/adjacency_list.cpp,  I only changed the 
edge container to be slist, and include 

I compiled it on linux with AMD opteron 844 processor.
gcc2.95.3 works fine, but gcc3.3 doesn't compile.

I think the reason is slist is not in std namespace in gcc3.3, and 
adjacency_list.hpp doesn't handle this correctly for slist.
...
grep BOOST_STD_EXTENSION_NAMESPACE adjacency_list.hpp
adjacency_list.hpp:    typedef 
BOOST_STD_EXTENSION_NAMESPACE::slist<ValueType> type;
adjacency_list.hpp:    typedef 
BOOST_STD_EXTENSION_NAMESPACE::hash_set<ValueType> type;
adjacency_list.hpp:    typedef 
BOOST_STD_EXTENSION_NAMESPACE::hash_set<ValueType> type;
adjacency_list.hpp:    struct bind_ { typedef 
BOOST_STD_EXTENSION_NAMESPACE::hash_set type; };
adjacency_list.hpp:    struct bind_ { typedef 
BOOST_STD_EXTENSION_NAMESPACE::hash_set type; };
should slist be handled the same way as hash_set ?

thanks
