I also encoutered the problem, but the WHL values are not negative...

@17824823008 `g++ -O3 -DNDEBUG -o ./kitti_eval/evaluate_object_3d_offline ./kitti_eval/evaluate_object_3d_offline.cpp` Try use this to compile evaluation code. I solved my problem by doing this.

I also look forward to the code of 2D detector.
