Hi, I am trying to use boost for my application and builds using command prompt on windows. I am using VC8.0 1) when I invoke build for the my code..i see the following error messages. Any clue?? "Unknown compiler version - please run the configure tests and report the results D:\boost\boost_1_34_1\boost/type_traits/is_integral.hpp(60) : error C2039: 'ulong_long_type' : is not a member of 'boost' D:\boost\boost_1_34_1\boost/type_traits/is_integral.hpp(60) : error C2065: 'ulong_long_type' : undeclared identifier D:\boost\boost_1_34_1\boost/type_traits/is_integral.hpp(60) : error C2913: explicit specialization; 'boost::is_integral' is not a specialization of a class template D:\boost\boost_1_34_1\boost/type_traits/is_integral.hpp(60) : error C2913: explicit specialization; 'boost::is_integral' is not a specialization of a class template D:\boost\boost_1_34_1\boost/type_traits/is_integral.hpp(60) : error C2913: explicit specialization; 'boost::is_integral' is not a specialization of a class template" 2) how to run $BOOST_ROOT/libs/configure on windows command prompt ?? appreciate any help. regards, praveen
