Jetson Nano And Yocto/poky Zeus

Question

I'm attempting to use the newest Yocto release to build an image to my Jetson Nano. For this I need CUDA 10 which is part of the NVIDIA binaries needed for the Jetson Nano image build.

CUDA 10 only supports GCC 7, so to get this working I'm using the meta-linaro layer to add an external toolchain. I put in

GCCVERSION = "linaro-7.2"
SDKGCCVERSION = "linaro-7.2"

In my local.conf and add the linaro layer to my bblayers.conf. When i then run bitbake image-name it then fails with the following error:

So it appears there is something wrong with the AUTOREV usage in the jdk bbfile? Any idea on how to fix this?
