Catkin_make issue

[pacrr]

Hello,
I was trying to build the package using the instructions you have published but I unable to resolve this issue:

/media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/src/Optimizer.cc:2216:10: warning: variable ‘bShowStats’ set but not used [-Wunused-but-set-variable] 2216 | bool bShowStats = false; | ^~~~~~~~~~ In file included from /usr/include/c++/9/map:61, from /media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/Thirdparty/DBoW2/DBoW2/BowVector.h:14, from /media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/include/KeyFrame.h:24, from /media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/include/MapPoint.h:23, from /media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/include/Map.h:23, from /media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/include/Optimizer.h:23, from /media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/src/Optimizer.cc:20: /usr/include/c++/9/bits/stl_map.h: In instantiation of ‘class std::map<ORB_SLAM3::KeyFrame*, g2o::Sim3, std::less<ORB_SLAM3::KeyFrame*>, Eigen::aligned_allocator<std::pair<const ORB_SLAM3::KeyFrame*, g2o::Sim3> > >’: /media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/src/Optimizer.cc:2344:37: required from here /usr/include/c++/9/bits/stl_map.h:122:71: error: static assertion failed: std::map must have the same value_type as its allocator 122 | static_assert(is_same<typename _Alloc::value_type, value_type>::value, | ^~~~~ /media/pacrr/99-quit/orb_ros_ws/src/orbslam3_ros/src/Optimizer.cc: In static member function ‘static void ORB_SLAM3::Optimizer::OptimizeEssentialGraph(ORB_SLAM3::Map*, ORB_SLAM3::KeyFrame*, ORB_SLAM3::KeyFrame*, const KeyFrameAndPose&, const KeyFrameAndPose&, const std::map<ORB_SLAM3::KeyFrame*, std::set<ORB_SLAM3::KeyFrame*> >&, const bool&)’:

Previous to this I had to change CV_LOAD_IMAGE_UNCHANGED to cv::IMREAD_UNCHANGED to resolve another issue, so this might be part of the problem but I am unsure. Any help is greatly appreciated, thanks.
