I also encountered this problem, which should have occurred on the Eigen version. Someone successfully switched to 3.3.0; But my solution is to modify the file Fast-Planner/fast_planner/poly_traj/include/poly_traj/polynomial_traj.h for (double i=3; i<order; i+=1) for (double j=3; j < order; j += 1) ， Change the double here to int, and modify it to for (int i=3; i<order; i+=1) for (int j=3; j < order; j += 1),ReferenceHKUST-Aerial-Robotics/Fast-Planner#92
