Sound like an error nothing to with dso_ros. Looks like the apt package for librealsense is outdated. Have you updated all apt packages? If yes, seems to be an upstream issue.
Neither DSO nor DSO_ROS use librealsense directly AFAIK. It might come in via pangolin though. You might want to try to compile librealsense yourself (e.g. http://wiki.ros.org/librealsense?distro=indigo in your catkin workspace) and then recompiling pangolin making sure it uses that.
Or maybe better, disable librealsense when compiling pangolin.
@NikolausDemmel Thank you for replying, I tried "apt-get update" but does not work. I have installed DSO and Pangolin following the instructions, when I download the some dataset, and using the command "./dso_dataset \ ***", it works well, so, can it say that pangolin has been installed correctly(it should used librealsense when compiling, am I right?), but when I want to use my own camera to run live dso, I download dso_ros branch and catkin_make it, the the errors show up. Should I compile pangolin again?
If both DSO and DSO_ROS link the same librealsense.so, and one works but the other doesn't, that is strange. Maybe you need to manually link some libusb for DSO_ROS, which seems to happen for DSO.
Otherwise, I don't know...

I try to reinstall the library using command "sudo apt-get --reinstall install 'ros-indigo-librealsense'", but is does not work, can anyone help me solve this problem? Thanks a lot.
