Hello. Quote from ISO_IEC_14882-2011, 5.1.2/10: > The identifiers in a capture-list are looked up using the usual rules for > unqualified name lookup (3.4.1); each > such lookup shall find a variable with automatic storage duration declared in > the reaching scope of the local > lambda expression. An entity (i.e. a variable or this) is said to be > explicitly captured if it appears in the > lambda-expression’s capture-list.
But this code successfuly compiled on gcc-4.6.1: #include <iostream> int main() { using std::cout; auto f = [&cout]() { cout << 1; }; // << f(); } http://liveworkspace.org/code/ae698b7daf7b5b531beafd9faaa6a409 But Intel C++ 12.1 says: error : a variable with static storage duration cannot be captured in a lambda Thanks. niXman.
