Hi, I am having some trouble using enable_if with gcc 3.4.4 (code below). Basically it is working as expected with functions ("bar"), but using it on member functions of a class ("Foo"), I am getting the error that this member function cannot be overloaded. Visual 2008 and gcc4 seem to be ok with it though. Any explanation and work around appreciated. B. -- #include <iostream> #include <boost/type_traits.hpp> #include <boost/utility/enable_if.hpp> // This won't compile with gcc 3.4.4 class Foo { public: template < typename T > typename boost::enable_if<boost::is_same<T, int>, T>::type bar(int x) { std::cout << "A" << std::endl; return x; } template < typename T > typename boost::disable_if<boost::is_same<T, int>, T>::type bar(int x) { std::cout << "B" << std::endl; return x; } }; // this would. template < typename T > typename boost::enable_if<boost::is_same<T, int>, T>::type bar(int x) { std::cout << "A" << std::endl; return x; } template < typename T > typename boost::disable_if<boost::is_same<T, int>, T>::type bar(int x) { std::cout << "B" << std::endl; return x; } int main() { bar<int>(1); bar<double>(1); Foo f; f.bar<int>(1); f.bar<double>(1); return 0; } ____________________________________________________ Michael Jackson, Susan Boyle, Black Eyed Peas ...
