unable to build kernel cache

Hi all, I am having some issues applying the root patches.

The system is a mac Pro 5.1 with a Sapphire Radeon RX580 8GB, running Sonoma 14.6.1, I'm using the OpenCore 1.5.0.

As the title suggests, the OpenCore patcher is unable to build the kernel cache due to an error 31. Having a closer look at the build log, it appears there are several symbols missing in the linking phase, in regards to the above mentioned graphics card. The KDK used is KDK_14.6.1_23G93.kdk.

Any suggestions regarding this?

Do let me know if anyone would want to see the entire log, or some more details are needed.

I will also try to patch the root from Monterey, and see how that goes.

Thanks!
