Hi folks, I'm trying my luck with the Boost.uBlas library, but I'm running into problems. This little snippet: #include <boost/numeric/ublas/matrix.hpp> using namespace boost::numeric::ublas; int main(int argc, char* argv[]) { identity_matrix<double> i(3); matrix<double> m(i); return 0; } should compile alright, shouldn't it? The compiler says: [BCC32 Error] matrix.hpp(2671): E2247 'identity_matrix<double,std::allocator<double> >::one_' is not accessible The same happens if I use the assignment operator instead of copy construction. Can anyone help me? As you've probably seen from the error message, I'm using the CodeGear (alias Borland) 2007 compiler. I'm using a BoostPro 1.37.0 installation. I haven't tried boost 1.38, but the change log doesn't explicitly state any uBlas-related changes. thanks Hendrik
