I built it in Release mode and stripped, but I can't reproduce this with the library built from source code. When I copied the libjog_controller.so to system, it works. What could be difference between source built library and the released library?

[7675t]

Any thought @534o ? Have you experienced the difference between local build and build farm's build?

[534o]

one possibility is you have rviz or other deb which is build before the newer the latest rostime, that includes changes in it's header files https://github.com/ros/roscpp_core/blob/kinetic-devel/rostime/CHANGELOG.rst you can check the build time by https://github.com/tork-a/88_tools/pull/20

easy way is to run apt-get dist-upgrade,

Great! You are totally correct and dist-upgrade solves it like a charm. Thanks!
