Some of our current dependencies include further catkin packages, which are not a dependency of maplab. If you build the complete workspace, these packages will fail due to missing dependencies of their own. This might change in the future, but for now there are two options:
Please only build maplab: catkin build maplab
or
Add CATKIN_IGNORE packages to the superfluous packages.
If you get an issue similar to this:
make[2]: /home/user/maplab_ws/devel/.private/maplab_common/bin/protoc: Command not found
make[2]: *** [compiled_proto/maplab-common/id.pb.cc] Error 127
make[2]: *** Waiting for unfinished jobs....
Make sure that your workspace layout is merge:
cd ~/$CATKIN_WS
catkin clean # Necessary to clean up your workspace as your layout will change.
catkin config --merge-develYou can check if your workspace is properly set up by running:
$ catkin config

Devel Space Layout: merged # <-- This should say `merged`.
Install Space Layout: None

...A known cause for this is an installed MATLAB using a network licence. The build can stall on getting the licence authenticated; so make sure that the licence server can be accessed, connect to the VPN if required.
make[5]: *** No rule to make target '/usr/lib/x86_64-linux-gnu/libGL.so', needed by 'lib/libopencv_viz.so.3.2.0'. Stop.
consider redefining the symbolic link that somehow got lost in your Ubuntu by:
sudo rm /usr/lib/x86_64-linux-gnu/libGL.so
sudo ln -s /usr/lib/libGL.so.1 /usr/lib/x86_64-linux-gnu/libGL.so
Install requests by calling:
sudo pip install requests
