Template methods of a template class

Template methods of a template class

Hi,

I have a segment of code which compiles and runs fine under g++ 3.3.3 but
not under 2.91.60 which is unfortunately what I am stuck using for the time
being. I have given a *very* artificial example below (also in .cpp file
attached) but the crux is that I can't seem to explicitly specify the
template parameters for a template function within a template class in
2.91.60.

Does anyone know if this is a limitation of the template code in the earlier
g++ or is there some trick to getting this to work? Any help would be
appreciated...

Regards
 Stuart

template<class T> class MyTemplate
{
 public:

  template<class C> C convert();
  T value;
};

template<class T> template<class C> C MyTemplate<T>::convert() { return
(C)value; }

...

MyTemplate<int> base_template;
base_template.value=100;

float f=base_template.convert<float>();

* The error is "syntax error before '<'"

A bit more information...

It seems template methods of a normal class have the same problem

class MyClass
{
  template<class C> C convert();
};
MyClass m;
float f=m.convert<float>();

is not happy either, while the following works fine outside a class

template<class C> C standalone_convert();
float f=m.standalone_convert<float>();
