[Boost-users] [boost::function] problem with void type as argument type

Hi! I have small piece of code and I do not know why it is not compiling - proper instantiation of function is not created. It means, why boost::function can not deduct types (code below). The problem is when type U is void. Can any one help me with it? Regards. template < typename T, typename U > void test ( boost::function & f ) { f(); } int f3() { std::cout << "f3(void)" << std::endl; return 3; } void f4() { std::cout << "f4(void)" << std::endl; return;// 4; } int main() { boost::function h = &f3; boost::function i = &f4; test (h); test (i); } -- |\/\/|   Seweryn Habdank-Wojewódzki \/\/
