Change Orientation of 3D coordinate system

Hello. I attached the picture below to describe my problem. I am using OpenGL to do an animation about rolling 3D coordinate OXYZ from A to B to C. Input: coordinate of cube: (0,0,0), (1,0,0) , (2,0,0), the cube rolling along its edge so the coordinate of cube center will rotate along the curve as the dash line. Problem: I created a function call DrawCoordSystem to draw Oxyz of the cube center. I could do rolling from 1st position to 2nd position; HOWEVER, at the 2nd rolling, when I call the DrawCoordSystem it will create oxyz within the same orientation (at the wrong way in the image) I do not know how to save the orientation of oxyz after the 1st rolling. Please help me to comments on the solution. Thanks a lot

Don't you do unit testing? Make a unit test for the code you posted, and post that on GitHub. I see you're following me on GitHub; that's great!

Thanks @taby. I am reviewing my code again and upload to github.
