could you please tell me what's wrong with my options? thanks in advance best

I defined EdgeSE3ProjectXYZ in the g2o version I provide with ORB-SLAM. It seems you are not correctly linking to that g2o version.

hi, @raulmur when I run lsd-slam, I installed the dependencies like "ros-indigo-libg2o", will it influence the g2o used in orbslam?

[liqile]

@raulmur when I first ran orb-slam, no such error happened, but after I installing and running lsd-slam, I could not running your orb-slam any longer

[raulmur]

The problem is that you are not linking to my g2o version, but "ros-indigo-libg2o".

[liqile]

@raulmur e.. how to linking to your g2o version? recompile orb-slam again?

@liqile Did you managed to make it work? I have exactly the same problem. (LSD-SLAM) Thanks

[liqile]

@husdo you can try the command:sudo apt-get remove ros-indigo-libg2o the ros distribution of mine is indigo, you should replace it with your ros distribution best
