Hi Mashiro, commit 2b50f7ab63685cd247e32ad321f7338ed130d3d5 Author: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx> kbuild: add workaround for Debian make-kpkg seems to prevent the use of GNUmakefile wrappers to set the ARCH and CROSS_COMPILE make variables. With this commit, I now see: make: Entering directory '/data/fs/linux-fs' Makefile:39: Do not include top Makefile of Linux Kernel *** *** Configuration file ".config" not found! *** *** Please run some configurator (e.g. "make oldconfig" or *** "make menuconfig" or "make xconfig"). *** Makefile:605: include/config/auto.conf: No such file or directory make: *** No rule to make target '.config', needed by 'include/config/auto.conf'. Stop. make: Leaving directory '/data/fs/linux-fs' Do you have a suggestion as to how to work around this? Here's a sample GNUmakefile content: CROSS_COMPILE := x86_64-linux-gnu- ARCH := x86_64 MFLAGS += CROSS_COMPILE=$(CROSS_COMPILE) ARCH=$(ARCH) export CROSS_COMPILE export ARCH include Makefile David
