In your real code, did you do something to make f public so test can use
it? But that isn't the main problem. Arturs Zoldners gave the solution
to the main problem:
If I understand correctly, while processing the definition of test, the
compiler doesn't look at the definition of C, so it doesn't know f is a
templated function, so it doesn't know how to parse the "<" in "c.f<int>".
When it instantiates test<T> it will, of course, look inside C<T> (for
at least the constructor of C and the declaration of f). But if it
can't process test at definition time, it never gets to instantiation.

why the following code cannot be compiled?
template <typename TC>
class C

template <typename TF>
void f() {}
};
template <typename T>
void test()
{
C<T> c;
c.f<int>();
}
gcc-4.3.2 on "c.f<int>();" reports error: expected primary-expression before
‘int’
