VeT,

I noticed you had a post on the NGD forum about this. Post

In NewtonJointLibraryMain.c, i believe you should replace the commented out lines with the uncommented lines. That works for me.

Code:
//typedef void NewtonUserJointDestructorCallback;
//typedef long NewtonUserJointSubmitConstraintCallback;
typedef void *NewtonUserJointDestructorCallback; 
typedef void *NewtonUserJointSubmitConstraintCallback;


Also, Julio has added some functions for the CustomHinge in the latest version 2.13. I made the following additions in your wrapper:

in NewtonJointLibraryMain.c:
Code:
// generic joint functions
...
JOINTLIBRARY_API NewtonJoint* CustomGetNewtonJoint (const NewtonUserJoint *joint); 
...
// Interface for a custom Hinge joint with Limits
JOINTLIBRARY_API dFloat HingeGetJointAngle (const NewtonUserJoint* hingeJoint);  
JOINTLIBRARY_API void HingeGetPinAxis (const NewtonUserJoint* hingeJoint, dFloat* pin); 
JOINTLIBRARY_API dFloat HingeCalculateJointOmega (const NewtonUserJoint* hingeJoint);


and in NewtonJointLibraryAPI.c:
Code:
// genetic joint functions
...
API (CustomGetNewtonJoint, jointlibrary)
...
// Interface for a custom Hinge joint with Limits
...
API (HingeGetJointAngle, jointlibrary) 
API (HingeGetPinAxis, jointlibrary) 
API (HingeCalculateJointOmega, jointlibrary)


I'd also like to say thanks for all your work on this! I find this wrapper very useful.
