So, while the simpler .C technique can be used, the .Call approach does not work. What are we missing here?
A real C++ compiler (and enough netiquette to wrap your lines). Why are you using VC++ with R: it is most definitely not the recommended C compiler? Using standard C++ and the recommended compiler usually works, modulo undefining symbols defined in windows.h or its dependencies. -- Brian D.
