[RESOLVED] static member functions in class templates

[ar115]

Hi,
Can anybody help me why this code does not compile (gcc 4.2.4)
what does the error "invalid operands of types ‘<unresolved overloaded function type>’ and ‘int’ to binary ‘operator<’" means?

--------------------------------------------------------------------------------------------------
struct foo {
template< int N >
static void increase( int& i );
};

template< int N >
void foo::increase( int& i )
{i += N;}

template< class T >
void f(){
int i=0;
T::increase<1>(i);
}

int main(){
f<foo>();
}
--------------------------------------------------------------------------------------------------

the line "T::increase<1>(i);" should be "T::template increase<1>(i);".

being T::increase a dependent name the compiler thinks that the '<''s in "<1> " are < operators, thus the cryptic error. The template keyword is used to disambiguate these situations.
