Build Problems for uavcan when building rover

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.

Hi , I have exactly the same problem, but trying to build on a fresh clone the first build example …

./waf configure --board CubeBlack
./waf copter

DsdlCompilerException: line 16, col 17: invalid syntax (, line 1)
line 16, col 17: invalid syntax (, line 1)

any suggestions?

thanks!
