ich hab ein Problem mit folgendem Codeschnippsel:

#include <list>

namespace blurt
{

class AxisAlignedBoundingBox;
class TraceableObject;
class Ray;

namespace kdtree
{
	typedef ::std::list<const blurt::TraceableObject*> ObjectList; // Zeile 24
	// ...
};
};

Der Code liefert beim Kompilieren eine ewig Lange Fehlerliste:

Ich hab keine Ahnung was genau da falsch gelaufen ist, dementsprechend waer ich fuer Hilfe dankbar

... namespace 'blurt::std' ...

Hast du evtl. die includes falsch positioniert, d.h. innerhalb deines Namespaces 'blurt'?
