Line #192 says there's no defconfig for your lineage based kernel
ninja: error: 'kernel/arch/arm64/configs/lineageos_oneplus3_defconfig', needed by '/home/mahadev/op3/out/target/product/oneplus3/obj/KERNEL_OBJ/.config', missing and no known rule to make it
Thanks for the reply.
It's there brother in "kernel/oneplus/msm8996/arch/arm64/". I have tried almost everything I can think of but still getting the error.
Also, I tried deleting and resyncing Kernel Sources along with clean and clobber build.
Any other help.
