The type in a dynamic_cast must be a pointer or reference to a complete class type, or void *
I believe you have to #include
the header file which contains the body of class osg::PositionAttitudeTransform
.
dynamic_cast
gives such error when the body of the destination class is not visible.
Here is the similar error reproduced in g++.

I am hoping there is someone out there who understands why the code below fails. I am trying to get an instance of PositionAttitudeTransform (Openscenegraph class) from an osg::Node* node object. But there is the compiler error below in bold.
void CameraPosCallbackUpdate::operator()(osg::Node* node, osg::NodeVisitor* nv) { // other code goes here osg::PositionAttitudeTransform* pat = dynamic_cast<osg::PositionAttitudeTransform*> (node); }
IntelliSense: the type in a dynamic_cast must be a pointer or reference to a complete class type, or void *
Please help me with correct way to access my object and I would appreciate help in understanding what the problem here is since I believe the cast should be possible.

Alok Save over 11 yearsYou need to show the declaration of
node
. As the error message says, it should be a pointer or reference to a complete type. -
Kobojunkie over 11 yearscode updated with more detail on where node is coming from.

Luc Danton over 11 yearsIs the type, in fact, complete? Is a definition for it visible from here?

Denis Ermolin over 11 yearsAs compiler said to you you have not included osg::PositionAttitudeTransform implementation

Kobojunkie over 11 yearsThank you. I had to remove the #include <osg/Transform> and replaced it with #include <osg/PositionAttitudeTransform>.
