Errors building the 10.13 Kernel

[Alexander von Below]

Hello,

I posted this in the darwin-kernel list a while ago, but am still stuck.

My goal is to build a 10.13 kernel, but make SDKROOT=macosx ARCH_CONFIGS=X86_64 KERNEL_CONFIGS=RELEASE XNU_LOGCOLORS=y BUILD_WERROR=0 is throwing several errors at me.

I have checked the various scripts on the internet, set up a 10.13.2 VM, installed Xcode 9.2 …

Anyone here who was successful in building the Kernel, or who could provide some help?

Or where do the Kernel people hang out these days?

Thanks

Alex
