Build Problems for uavcan when building rover

(brendon) #1

Hi,
I’m building the rover on cygwin from the latest ardupilot source and am having problems building uavcan as seen in below error.

Compiler failure
Traceback (most recent call last):

My build configuration output is below if it helps.
