Hi,
i try to use modules_install target after building kernel with KBUILD_OUTPUT set
KBUILD_OUTPUT: /media/data_nvme/git/kernel/build #kernel source is in
/media/data_nvme/git/kernel/BPI-R2-4.14
kernel is build successfully, but i fail on running the make modules_install
target
ERROR: Kernel configuration is invalid.
include/generated/autoconf.h or include/config/auto.conf are missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.
Makefile:648: include/config/auto.conf: No such file or directory
make: *** [Makefile:719: include/config/auto.conf] Error 1
it looks it is ignoring the KBUILD_OUTPUT variable, as both files are present
$ ls /media/data_nvme/git/kernel/build/include/config/auto.conf
/media/data_nvme/git/kernel/build/include/config/auto.conf
$ ls /media/data_nvme/git/kernel/build/include/generated/autoconf.h
/media/data_nvme/git/kernel/build/include/generated/autoconf.h
i also tried adding KERNEL_DIR var, but also without success
sudo make ARCH=$ARCH KERNEL_DIR=$KBUILD_OUTPUT
INSTALL_MOD_PATH=/media/$USER/BPI-ROOT/ modules_install
$KBUILD_OUTPUT is definitely set to right directory (checked on beginning of my
function)
this message seems to be triggered by Makefile in root (here i tried to add the
KBUILD_OUTPUT in the test before include without success)
718 include/config/auto.conf:
719 $(Q)test -e include/generated/autoconf.h -a -e $@ || ( \
720 echo >&2; \
721 echo >&2 " ERROR: Kernel configuration is invalid."; \
722 echo >&2 " include/generated/autoconf.h or $@ are missing.";\
any idea?
regards Frank
