[BUG] Linking issue when installing from source

[bergercookie]

When I run the fetch gazebo simulation stack and fetch_navigation/fetch_nav.launch (installed from apt) it works fine. However repeating the same procedure, after cloning fetch_ros (i.e., fetch_navigation) in my local workspace and after compiling the workspace packages with catkin_make, I'm getting the following error when running the navigation (I've the log in this ticket):

$ roslaunch fetch_navigation fetch_nav.launch

...

/opt/ros/melodic/lib/move_base/move_base: symbol lookup error: /home/user/ros_ws/devel/lib/libfetch_depth_layer.so: undefined symbol: _ZN2cv4rgbd9depthTo3dERKNS_11_InputArrayES3_RKNS_12_OutputArrayES3_

To Reproduce

• Clone fetch_gazebo, and fetch_ros in the local workspace, and compile
• roslaunch fetch_gazebo playground.launch on one window
• roslaunch fetch_navigation fetch_nav.launch on the other --> this should fail due to an undefined symbol

catkin workspace (please complete the following information):

• fetch_ros version: (e831ff0223ca55e8f4f1d6e5ee2ca49fd06ebe7)
• Ubuntu version: 18.04
• ROS version: latest melodic from apt

Additional context

Running this inside a ubuntu 18.04 docker.

Have you installed all of the dependencies using rosdep?

When installing via apt, the package dependencies are installed automatically. Building from source in a Docker, will fail to compile without the compile time dependencies, and will fail to run without the execution time dependencies.

These Dockerfiles are out of date but both run rosdep.

I hadn't, no, good point. However, having installed all the dependencies with rosdep, and having removed the devel/lib/libfetch_depth_layer.so generated object (so that it creates it again), I'm still getting this error.

I'm using catkin_make instead of catkin to compile, but I don't think that difference matters

This is definitely odd. I haven't taken the time to try the repro (but thanks for the steps!)... a stab in the dark is: You could try putting a CATKIN_IGNORE in the fetch_depth_layer/ folder and do a clean build from there.

Sure, that's actually my current mitigation; it compiles and executes the navigation gazebo demo successfully.
