I have been able to build before but for some reason I deleted the IDE so I had to download it again and now I cant build. Doesn't give any error messages so I dont even know where to start.
I downloaded the modified version of the IDE and configured it according to the instructions.I also cloned a new copy of trunk from github.
This is all that the IDE says when I press verify.
Here are my preferences:
I have also selected HAL Board->ArduPilot Mega 2.x and restarted.
Any help wold be much appreciated.
