AFAIK, WindRiver uses a modified version of g++, which is licensed under the GNU GPL, requiring them to release the full source code. Where might I get a copy?
I am setting up my computer (running Ubuntu GNU/Linux) with the development environment, and I want to get a compiler working. I’ll leave being able to load the code onto the robot until next year.
EDIT:
Found it on FIRST Forge.
Here it is for anybody else who needs it:
