for debug purposes only I managed to get it to:
programwnd:
#include "prgengine.h"
prgengine.h:
#include "rtexec2.h"
class CProgramWnd;
class Prgengine{
private:
map<string,CBREQ> variableMap;
programwnd *m_masterWnd ;
}
prgengine.cpp:
#include "PrgStackEngine.h"
#include "programwnd.h"
which removes the need for forward declaration through nested headers
(ick), but it works for debugging and getting this going.
and I get ~20 of about these error messages: Is that a problem?
