For example, is the following supposed to compile on MSVC10? #include<boost/mpl/identity.hpp>
int main() { typedef typename boost::mpl::identity<int>::type t; t i = 0; return i; } This code does not compile on my copy of MSVC10.
-->error C2899: typename cannot be used outside a template declaration
Thanks. Is anyone positive about what the C++11 standard says in this case? This code compiles on my GCC 4.5.3 with -std=c++0x... who's right MSVC or GCC?
I don't know what the c++11 standard says, but as there are some compilers that don't support it and this was not allowed on C++03 compilers you should live with this constraint and the use of typename outside templates. Best, Vicente
