The library is known to work with several newer compilers, VC7.1 among them. Help with other compilers is welcomed.
I've tried it with bcc32 5.6.4 and just #include <boost/singleton.hpp> leads to these errors. If anyone has any ideas on this then I'd be happy to try them out.
Cheers

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 > { };

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; } -Jason
