I got similar bit subtly different errors using MSVC2010 in 64-bit on Win7
Note this required installing the 7.1 SDK (and uninstalling the previously
present MSVC2010 redsitriutable!)
On MSVC2010/64 instead I was seeing unable to match and of the 12 overloads
for get(...)
In both cases though seems to hinge on being unable to resolve a property map
of weights to edges (or something)...
The above statement is a bit vague, I know.... more concretely, I noted the
following differences between Boost 1.54 (MSVC2008, fails) and 1.42 on debian
squeeze:
inside djisktra_shortest_paths() :
boost 1_54
void examine_edge(Edge e, Graph& g) {
// Comparison needs to be more complicated because distance and weight
// types may not be the same; see bug 8398
// (https://svn.boost.org/trac/boost/ticket/8398)
D source_dist = get(m_distance, source(e, g));
if (m_compare(m_combine(source_dist, get(m_weight, e)), source_dist))
boost::throw_exception(negative_edge());
m_vis.examine_edge(e, g);
}
boost 1_42
template <class Edge, class Graph>
void examine_edge(Edge e, Graph& g) {
if (m_compare(get(m_weight, e), m_zero))
boost::throw_exception(negative_edge());
m_
I am currently rebuilding with boost 1.42 to see if that succeeds on MSVC2008...
this will be a slow process, because I find myself reverse engineering how it
all hangs together and having to write chains to find out what a type
ultimately resolves to and untangle all the 'legendary' template compiler
messages, being currently unfamiliar with this end of the code
Ultimately I may end up having to write some test harnesses that narrow things
down (and speed up the build process!)

Boost should be reasonably well supported on Windows but BGL is very
challenging for compilers. Iirc from MSVC++, sometimes required hinting for it
to derive the correct type templates. Gcc will literally try every possible
combination as required by C++ spec but MS compiler does not in order to get
faster compile times.

Hiya,
64-bit on Windows 7 + MS7.1SDK fails with same error as XP+32bit+MSVC8
I'm wondering if boost_1_54 is the culprit, using some lately added C++
standard stuff unsupported by MS
Next move is to try boost_1_42 (same as squeeze) and see if that works
Othwrwise time to start debugging...
