Hey everyone, FRCSim maintainer here...
A few issues to address:
if your C++ code doesn't compile do follow the instructions prensing posted. This can happen if you install a version of Gazebo we didn't anticipate. This will happen on other versions of Ubuntu. It's an easy fix, just right click on the project and go to C++ Settings > includes > and change the sdf or gazebo folder to the one on your computer.
If you get those errors about boost, that tells me you're using a version of Ubuntu other than 14.04...
I know we said this would work, but the issue here is dependencies. You'll need to install libprotobuf-8 and boost 1.54
