Subject: [PATCH] kbuild/builddeb: Fix building .deb packages out-of-tree
Date: Thu,  8 Nov 2018 20:56:24 +0100	[thread overview]
Message-ID: <20181108195624.25410-1-bp@alien8.de> (raw)

From: Borislav Petkov <bp@suse.de>

When building a .deb package with

  make O=/tmp/b oldconfig
  cd /tmp/b
  make bindeb-pkg

the build fails with

   fakeroot -u debian/rules binary
  ***
  *** Configuration file ".config" not found!
  ***
  *** Please run some configurator (e.g. "make oldconfig" or
  *** "make menuconfig" or "make xconfig").
  ***
  make[12]: *** [/mnt/kernel/kernel/linux/scripts/kconfig/Makefile:69: syncconfig] Error 1
  make[11]: *** [/mnt/kernel/kernel/linux/Makefile:544: syncconfig] Error 2
  make[10]: *** [Makefile:640: include/config/auto.conf] Error 2
  make[9]: *** [Makefile:15: __sub-make] Error 2

because ($MAKE -s image_name) in the subshell is missing KBUILD_SRC and
cannot find .config. Passing in KBUILD_SRC= for the current pwd fixes
the build.
