There's
one thing that you may notice with kernel's that have split source/build
dirs
(like linux-yocto), is that once you have gone through the configure phase
and drop into the devshell you may not have KBUILT_OUTPUT set to the
build directory, and end up dropping files in the source dir .. which causes
you
mrproper and build issue.
I have a local append to devshell that sets:
d.setVar("KBUILD_OUTPUT", "${B}")
To make sure things work. If you need something like this as well, or have
problems with linux-yocot, I can arrange to have something like this added
by default. But since no one else has asked about it, I assumed no one else
is either using devshell, or they haven't run into it.
Cheers,

Dear Bruce,
I'd like to have the same behaviour as before, so what you suggested
would suit me.
Could you please tell me where to add that line?
Fileneme and function.
Apply the patch to your yocto/oe-core repository (master branch, but
it should apply to danny as well). This will be part of my next
consolidated kernel pull request, so you'll only need to carry
it locally for a short time.
Cheers,
Bruce
Thank you

Hello,
I was used to work with oe-classic.
When I used oe-classic, often I used the 'devshell' option to try to
compile (make uImage) the kernel with the entire environment set up
correctly.
Now if I do the same procedure with Yocto 8 Danny it does not work.
For example I'm using a default configuration below:
1st step
---
MACHINE="beagleboard" bitbake -c devshell virtual/kernel
Build Configuration:
BB_VERSION = "1.16.0"
TARGET_ARCH = "arm"
TARGET_OS = "linux-gnueabi"
MACHINE = "beagleboard"
DISTRO = "poky"
DISTRO_VERSION = "1.3"
TUNE_FEATURES = "armv7a vfp neon cortexa8"
TARGET_FPU = "vfp-neon"
meta
meta-yocto
meta-yocto-bsp = "danny:09031ac2fc0f30ec577ee823fc61ff0e5d852e21"
NOTE: Resolving any missing task queue dependencies
NOTE: Preparing runqueue
NOTE: Executing SetScene Tasks
NOTE: Executing RunQueue Tasks
NOTE: Tasks Summary: Attempted 912 tasks of which 912 didn't need to be
rerun and all succeeded.
2nd step just after 1st
------------------------
MACHINE="beagleboard" bitbake -c devshell virtual/kernel
- Devshell starts in a new screen
------------------------
$ pwd
~/yocto-8-danny/poky/build/tmp/work/beagleboard-poky-linux-gnueabi/linux-yocto-3.4.11+git1+a201268353c030d9fafe00f2041976f7437d9386_1+449f7f520350700858f21a5554b81cc8ad23267d-r4.3/linux
- lauch a kernel build (as I was used to do)
------------------------
$ make
scripts/kconfig/conf --silentoldconfig Kconfig
***
*** Configuration file ".config" not found!
***
*** Please run some configurator (e.g. "make oldconfig" or
*** "make menuconfig" or "make xconfig").

make[1]: *** [silentoldconfig] Error 2
make: *** No rule to make target `include/config/auto.conf', needed by

I would like to find out whether you can still do this and what is the new
way to go
As Chris said, this way should still work, and it does work here for me.
There's
one thing that you may notice with kernel's that have split source/build
dirs
(like linux-yocto), is that once you have gone through the configure phase
and drop into the devshell you may not have KBUILT_OUTPUT set to the

d.setVar("KBUILD_OUTPUT", "${B}")

Subject: [PATCH] kernel-yocto: add KBUILD_OUTPUT to OE_TERMINAL_EXPORTS
Since linux-yocto based recipes have a split build and source directory,
we should export KBUILD=${B} to the devshell. This allows the kernel to
be incrementally build within the shell and not dirty the source
directory (which breaks subsequent full builds).
