My colleague generated an OCC 6.5.2 wrapper version and also ported the projects on Visual Studio 2010. Everything compiles smoothly and Naro runs. Together had a debugging sessions to see what problems appeared with this porting.
There are some memory leaks that need to be solved, the selection seems to be broken, also the Naro tools need some fixing. Not all fixing is related to 6.5.2 wrappers, some of the fixing is caused by some OCC 652 changes in API functionality.
Next step is to fix the selection, point and line tools to see if with these tools everything goes ok. In parallel also the memory leaking on wrappers will be fixed.
