The following programs does not compile with error

foo.cpp: In function `int main()': foo.cpp:11: no matching function for call to `foo(std::string)'

Program code:

#include <boost/call_traits.hpp> #include <string>

template<typename Type> void foo(typename boost::call_traits<Type>::param_type x) { }

int main() { foo(std::string("bar"));

return 0; }

Compiler cannot deduce 'Type'. You have two options: 1. explicitly state type: foo<std::string>(std::string("bar")); 2. go to const& /Pavel
