hai everyone

i am using nkrkv/af-motor/dc-motors for controlling my dc motors.  
i worked fine on older version of xod ( version 0.34 ) .but after updating the xod to version 0.35.2, thenkrkv/af-motor/dc-motors showing error while uploading . please help … other nodes worked fine.

this is the error message.

Error during build: exit status 1  
Compilation failed  
Command Process exited with code 1  
The generated C++ code contains errors. It can be due to a bad node implementation or if your board is not compatible with XOD runtime code. The original compiler error message is above. Fix C++ errors to continue. If you believe it is a bug, report the problem to XOD developers.

please help…
