Error while loading shared libraries: libg2o_ext_freeglut_minimal.so: cannot open shared object file: No such file or directory about rgbdslam_v2 HOT 3 CLOSED

I have solve it.

1. add the lib path where the lib you missed into /etc/ld.so.conf
2. using sudo ldconfig to make it working
3. finally roslaunch

from rgbdslam_v2.

It seems you are missing a library that should come with g2o. I do not know how to solve this. Do you have libg2o_ext_freeglut_minimal.so in your system?

from rgbdslam_v2.

I have the same problem.
But I have make sure that there's libg2o_ext_freeglut_minimal.so file in my system. By using
ldconfig -v | grep "g2o"
I can find it.

But it still report the error
