Subject: [question] KBUILD_OUTPUT and modules install (with INSTALL_MOD_PATH)

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

KBUILD_OUTPUT is an environment variable.

Did you set (export) it
before doing 'make modules_install'?

This is no variable like KERNEL_DIR.

"git grep KERNEL_DIR" obviously has no hit
in the kernel directory.

Yes i exported it before use at beginning of my script [1] and modules_install used inside install function [2]. It works with build-function [3].
As the script is big i linked the relevant parts...i checked KBUILD_OUTPUT at beginning of install function so i'm sure it was set

[3] is unrelated since
"#&& make modules_install 2>&3" is commented out.


In [1], you export KBUILD_OUTPUT as a normal user,
then in [2], you run the commands with 'sudo'.

That is why KBUILD_OUTPUT was not passed.

i just wanted to point to build-process where KBUILD_OUTPUT is used :)

thank you very much...i remember why (because the sudo) i passed the vars here i already exported ;)

i tried the KERNEL_DIR here (found somewhere but not checked in Makefile), but not the KBUILD_OUTPUT, don't ask me why...with passing KBUILD_OUTPUT there all works as expected.

sudo make ARCH=$ARCH INSTALL_MOD_PATH=$INSTALL_MOD_PATH KBUILD_OUTPUT=$KBUILD_OUTPUT modules_install

Thanks for pointing to this ;)
