Can you try installing dwarves package and try the build again?

sudo apt update
sudo apt install dwarves

thanks you for your info.

Unfortunately, I also have errors after successfully installing dwarves like:

sys64.o: error: objtool: .text+0xf9: unreachable instruction
make[4]: *** [/usr/src/linux-headers-6.17.0-14-generic/scripts/Makefile.build:430: sys64.o] Error 1
make[4]: *** Deleting file 'sys64.o'
make[4]: *** Waiting for unfinished jobs....

make[2]: *** [/usr/src/linux-headers-6.17.0-14-generic/Makefile:248: __sub-make] Error 2
make[1]: *** [Makefile:248: __sub-make] Error 2

Thanks again. Binh

There might have been 2 issues with your build.

and one of them was resolved by installing dwarvs.

to resolve the another issue, add --make-args="OBJECT_FILES_NON_STANDARD_sys64.o:=y" in the build command like below

./build-driver -ni --make-args="OBJECT_FILES_NON_STANDARD_sys64.o:=y"
