            Bug ID: 15820
           Summary: make linux-menuconfig does not modify correct .config
                    file when LINUX_KERNEL_CUSTOM_CONFIG_FILE set
           Product: buildroot
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: gary.isliefson@ametek.com
                CC: buildroot@uclibc.org
  Target Milestone: ---

I want to have the linux source files in an alternate tree from where buildroot
places them after the download. I've successfully done this by using the
local.mk file with an entry LINUX_OVERRIDE_SRCDIR=/home/me/some-path.

make linux-rebuild then correctly builds from the source files in the new path. 

However, if I run make linux-menuconfig, it modifies the .config file in its
build directory (which is under buildroot at output/build/linux-custom/.config)

I found the variable BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE in buildroot's make
menuconfig, and I thought this would do what I want (ie, modify the .config in
my linux source directory), so I set this var to
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE=/home/me/some-path/.config

Then make linux-reconfigure, it rebuilds linux, but appeared to again use the
wrong .config file, then make linux-menuconfig still modifies the .config in
output/build/linux-custom, rather than modifying the one in my source directory
(/home/me/some-path/.config).

Correct me if I'm wrong, but setting BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE
shouldn't buildroot make linux-menuconfig modify the one pointed to by this
variable? So far, I've had to run make linux-menuconfig, then manually copy the
output/target/linux-custom/.config to my actual linux source directory in order
to preserve the changes.

Garyl, All,

Thanks for your report.

No, BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE is used as the "source" for the
configuration, it is not meant to be the "working copy", so the behaviour
you report is the expected one.

You want to run:  make linux-update-defconfig   (or: linux-update-config)
See help, with:   make help

Yann E. MORIN.
