The previous line makes me worry that CRTP will not work on your compiler. CRTP is a major foundation for the library, so if it doesn't work it may not be possible to find a work around. Does the following compile?

template < typename Type > struct Base { Type * ptr; };

struct Derived : public Base < Derived > { };

Yes, this compiles fine.

These might be the result of some compiler problem with friends inside templated classes. See if this compiles:

template < typename Type > class Outer { private: typedef Type some_type;

class Inner { typename Outer < Type >::some_type inner; } inner;

friend class Inner; };

int main ( ) { Outer < int > test; return 0; }

This also compiles fine. Thanks Russell
