Hi,

While compiling with Intel C++ 7.1 Boost Python , i get this kind of error on class.cpp and a lot of other Boost Python files :

C:\boost-1.30.2\boost/type_traits/is_integral.hpp(39): error: class "boost::is_integral<unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true)

I think that there must be a define that i missed somewhere ! I don't find it Any idea ?

Are you using Boost.Build? Are you using the CVS version of Boost.Python?

Works fine for Intel7.1/windows when I do it.
