I used the opencv4.2.0 ,and occur this problem:

/home/music/catkin_ws/src/ORB_SLAM2/src/PnPsolver.cc:841:6: error: no declaration matches ‘void ORB_SLAM2::PnPsolver::gauss_newton(const CvMat*, const CvMat*, double*)’

Could you please give me a hand !
Thank you!

I met the same problem with Opencv4.2.0. Have you solved it?
