Hi,
Please try below steps,
$ cd $KERNEL
$ make mrproper
$ cp path/to/valid/config/file .config
$ make mrproper
$ cp path/to/valid/config/file .config
$ make menuconfig
$ make O=/abs/path/to/output
Thanks!

Hi,
I'm unable to build the kernel using the O=path/to/out option. Am I
doing something brain dead?
$ cd $KERNEL
$ make mrproper
$ cp path/to/valid/config/file .config
$ make O=/abs/path/to/output
...
scripts/kconfig/conf --syncconfig Kconfig

So I tried copying the .config file to the output directory
$ cp .config /abs/path/to/output
$ make O=/abs/path/to/output
...
Using /home/tobin/build/kernel/linux as source for kernel
/home/tobin/build/kernel/linux is not clean, please run 'make mrproper'
in the '/home/tobin/build/kernel/linux' directory.
/home/tobin/build/kernel/linux/Makefile:1091: recipe for target 'prepare3' failed
make[1]: *** [prepare3] Error 1
make[1]: Leaving directory '/home/tobin/build/kernel/output/master'
Makefile:146: recipe for target 'sub-make' failed
make: *** [sub-make] Error 2
Same thing if I use KBUILD_OUTPUT instead of passing O=
thanks,
Tobin.
