Whenever I call the function "rendering::Scene::VisualAt" or "Camera::ZValue", it complains:
gzserver: symbol lookup error:
catkin_ws/devel/lib/librand_camera.so:
undefined symbol: _ZN6gazebo9rendering6Camera6ZValueEii
in which "rand_camera" is the my project name. Anyone knows how to solve this? I really appreciate it!!
