Unimplemented C++ feature big_integer.hpp line 153
The portion in question is
template<class T> friend bool operator<(T lhs, const expression<Base>& rhs) { return rhs > lhs; }
which doesn't strike me as all that odd, but maybe I'm missing something. I'll try to look at it more, later and see if I can fix the problem.
Maybe something as simple as moving the definition...
template<class T> friend bool operator<(T lhs, const expression<Base>& rhs);
...
template<class T> bool operator<(T lhs, const expression<Base>& rhs) { return rhs > lhs; }
I got a chance to fiddle with it, and this solution seems to work. CW Pro 9.2 does not currently like friend template definitions in the class. Even the very simple example class Foo { public: template<class T> friend operator<(T lhs, const Foo& rhs) { return rhs > lhs; } }; triggers the "unimplemented feature" error. However, if the definition is moved out of the class, the error goes away. Richard, is it going to mess up anything else to move these outside the class? John
