Hi Kyungsoo, I used Kubuntu 16.04 for development and haven't seen an error like you've described so there must be something specific to your system that is causing the problem.
Did you build the OSG youself or did you pull it into from a repository? If you built it yourself did you get any compile errors? Have you tried any other versions of the OSG? Robert.
