Hi, In the range regression I get errors like cc-1282 CC: ERROR File = /txusr/rwgrosse/boost_regression/boost/boost/range/empty.hpp, Line = 38 More than one instance of overloaded function "boost::begin" matches the argument list. Function symbol function template "boost::begin(T &)" is ambiguous by inheritance. Function symbol function template "boost::begin(const T &)" is ambiguous by inheritance. The argument types are: (const std::pair<std::vector<int, std::allocator<int>>::iterator, std::vector<int, std::allocator<int>>::iterator>). return boost::begin( c ) == boost::end( c ); I don't know this compiler, but could it be that it does not configures BOOST_NO_FUNCTION_TEMPLATE_ORDERING properly? (I assume by the error above mipspro should define the macro to 1) If so, can somebody fix it? Thanks Thorsten
