there is an error in ORB_SLAM2_modified and I don't find the reason. Can you help me about this error?

@DamonMIN You need to install the modified g2o first, not just compile it but install it into /usr/local (by default). Also make sure your cmake find this modified g2o when building ORB_SLAM, otherwise it may report an error. If you have installed the g2o in ROS library (via apt) I suggest to uninstall it too.

@gaoxiang12 @DamonMIN actually the modified g2o's default output directory is into /ORBSLAM2_with_pointcloud_map-master/g2o_with_orbslam2/lib, I've inspected it via ccmake.However I also have the same lib into my usr/local/lib somehow,so I don't know which lib support my program.I guess you could cp the default lib to the /usr/local.

@gaoxiang12 Is the "ORB_SLAM2_modified" only support by the "modified g2o"? can i use the g2o lib that i compile in the origional ORB_SLAM2?thanks
