when I use catkin_make hector_quadrotor ,the following errors will be appear.please help me!!!thank you!
1、/hector_quadrotor_tutorial/src/hector_localization/hector_pose_estimation_core/src/measurements/poseupdate.cpp:385:73: error: cannot convert ‘const Eigen::CwiseBinaryOp<Eigen::internal::scalar_product_op<double, double>, const Eigen::CwiseNullaryOp<Eigen::internal::scalar_constant_op, const Eigen::Matrix<double, 1, 1, 0, 1, 1> >, const Eigen::CwiseBinaryOp<Eigen::internal::scalar_difference_op<double, double>, const Eigen::Matrix<double, 1, 1, 0, 1, 1>, const Eigen::Matrix<double, 1, 1, 0, 1, 1> > >’ to ‘double’ in initialization double error2 = error.transpose() * Ix * (Ix + Iy).inverse() * Iy * error;

I think the problem is the version of Eigen. Try installing Eigen3 and then proceed.
