build issue in tests about kdbus HOT 7 CLOSED

Have you built the kernel at /home/bryan/build/linux/ yet?
The tests have "issues" if you don't set up your kernel tree properly, best bet, install 3.17-rc on your machine and run the tests that way, you need to in order to be able to test the code at the moment anyway :)

Yes, the 3.17-rc kernel was built and running when I did the kdbus build. I did the build with debian make-kpkg.

I have no idea what the debian package does, but it looks like the kernel source headers aren't included properly somehow, sorry, you are on your own here.

Ah, I see. I think I found a bug in kernel-package. Thanks!

Actually, I spoke too soon. I get the same problems with fresh clones building by hand:

cd ~/build
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
cp ../current.config .config
make oldconfig
make -j4 && sudo make modules_install && sudo make install
reboot

make install on debian will automatically build the initramfs and update the grub.cfg so next boot will be my new kernel.

cd ~/build
git clone https://github.com/gregkh/kdbus
make

and I am back to the same error in the OP.
So, maybe I need to bisect upstream to see where it broke?

from kdbus.

try 'make headers_install' and see if that helps. There was an email thread about these issues a few weeks ago on the systemd mailing list, I thought we figured out all the odd combinations, but I guess not,

from kdbus.

Ah-ha! Ok, so for both builds I've done, neither of them 'make headers_install' to the build directory.
The first build (with make-kpkg) makes a linux-headers package, and does symlink to the location of the installed headers in /lib/modules/<version>/{build,source}, but for some reason kdbus was looking at my actual build directory.

So running headers_install (without setting INSTALL_HDR_PATH) fixed the second build done by hand.
It does seem that the issue is either with the way that the upstream kernel installs headers (when INSTALL_HDR_PATH is set - external to the build directory), or how kernel-package symlinks to the installed header path.
Neither of these have to do with kdbus, so closing this here.
