It seems these two files can not be both included,

just two line file:

#include <boost/bind.hpp> #include <boost/mpl/less.hpp>

will fail to compile on vc 7.1

change value to value_t in bind.hpp can resolve the problem.

Lijun, It's a known problem that has been fixed in the CVS. The fix will appear in the next release. Thanks for the report, -- Aleksey Gurtovoy MetaCommunications Engineering
