I'm trying to port a previous project to catkin , which has been made in rosbuild. After rewriting the CMakeLists.txt I encounter the following compiler error:

The problem is actually most likely not with your build scripts, but with how you use certain pieces of ROS infrastructure. Can you show us some code around ControlManager.cpp:518?

Thanks for your reply!! I edited the original post. It shows the whole void CControlMgr::callbackViconData(const crazypkg::ViconData& msgViconData) which is part of ControlManager.cpp The Line 518 is at the end
