HI All, Just jumped on the OVSM bandwagon! Ordered myself a board and downloaded everything i could download. I am now in the process of trying to compile the code. Followed the OVMS v3 Developer Guide to a T. Still, pretty far down the list it throws an error. I would be great full if someone could point me to a solution for this. The full log is attached.
