Gazebo: undefined reference to `clock_gettime'

Question

Linking CXX executable gazebo-non-ros libgazebo_server.so.0.10.0: undefined reference to clock_gettime' collect2: ld returned 1 exit status make[4]: *** [server/gazebo-non-ros] Error 1 make[4]: Leaving directory /home/klapfer/ros/stacks/simulator_gazebo/gazebo/build/gazebo/build' make[3]: *** [server/CMakeFiles/gazebo-exec.dir/all] Error 2 make[3]: Leaving directory /home/klapfer/ros/stacks/simulator_gazebo/gazebo/build/gazebo/build' make[2]: *** [all] Error 2 make[2]: Leaving directory /home/klapfer/ros/stacks/simulator_gazebo/gazebo/build/gazebo/build' make[1]: *** [installed] Error 2 make[1]: Leaving directory `/home/klapfer/ros/stacks/simulator_gazebo/gazebo' CMake Error at CMakeLists.txt:32 (message): Build of Gazebo failed

I just changed computer this morning and when trying to compile the gazebo_simulator I get this error. It is computer depended, but I have no clue where the error comes from.

I hope I can find some help here. Thank you all in advance.

Answer 1

Modifying the file: ~/ros/stacks/simulator_gazebo/gazebo/build/gazebo/server/CMakeLists.txt helped.

target_link_libraries( gazebo-exec ${libtool_library}
                               ${gazeboserver_link_libs} 
                               ${boost_libraries} 
                               ${assimp_libraries} 
                               ${freeimage_library} 
                               gazebo_server
                               gazebo_rendering
                               gazebo_av-shared
                               gazebo_gui
                               gazebo_physics
                               gazeboshm 
                               assimp
                               pthread
                               -lrt

)

But is is not optimal and the changes are undone when cleaning the project. If someone knows a solution to this it would be nice to share it here.

Thank you.
