I ran into an error during compilation of> the kernel, more specifically the dtb-overlay:
DTC arch/arm64/boot/dts/qcom/apq8016-sbc.dtb
./scripts/dtc/dtc: invalid option -- '@'
Usage: dtc [options] <input file>
...
make: Leaving directory '/home/android/src/build_TWRP_minimal_manifest/kernel/fairphone/sdm632'
ninja: build stopped: subcommand failed.
20:39:13 ninja failed with: exit status 1
I managed to fix that by compiling with:
export DTC_EXT=$( which dtc );
mka recoveryimage
