Hi all, I'm trying to compile boost::numeric::ublas with NVCC and I get the following errors: /usr/local/include/boost/type_traits/has_new_operator.hpp:28: error: `&' cannot appear in a constant-expression /usr/local/include/boost/type_traits/has_new_operator.hpp:28: error: template argument 2 is invalid This is related to #3919 and #3980 in a effort to make NVCC work with boost. Is there a known workaround so that I could tweak boost/config/compiler/nvcc.hpp? I'm using trunk under linux with the following piece of code: // Boost headers #include <boost/numeric/ublas/matrix.hpp> int main() { typedef boost::numeric::ublas::matrix<float> host_matrix_type; host_matrix_type host_mat; return 0; } Regards, Denis

I will give it a look monday when I have acces to our GPU machine. I think it's related to nvcc support for template, especially SFINAE. -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35

Looks like it's treating SFINAE correctly, at least for release 3.0 of NVCC (code from Wikipedia): #include <iostream> struct Test { typedef int Type; }; template < typename T > void f(typename T::Type) // definition #1 { std::cerr << "definition #1" << std::endl; } template < typename T > void f(T) // definition #2 { std::cerr << "definition #2" << std::endl; } int main() { f<Test>(10); // call #1 f<int>(10); // call #2 without error thanks to SFINAE return 0; } Returns: definition #1 definition #2

Removing boost/type_traits/has_new_operator.hpp in type_traits.hpp solved the problem (obviously).
