[Xenomai-core] Buildbot: Failure building Xenomai kernel for TQM860

[Niklaus Giger]

Hi

I get an error building the TQM860 image (2.4 based kernel). Last successful 
build was with revision 1920 (didn't build between).
Log is available under 
http://ngiger.dyndns.org:8011/tqm_f/builds/30/step-mk_kernel/1

Best regards

Hi Niklaus,

I just compiled my Linux 2.4 kernel for TQM860L with the latest revision 
of Xenomai and I cannot reproduce your problem. In you linker path there 
are no Xenomai objects. How does it come? Do you use --arch=ppc with 
prepare_kernel (--arch=powerpc is not valid any more for the ppc tree).

Wolfgang.

The problem pops up with CONFIG_XENO_OPT_SCALABLE_SCHED.

The definition of xnlogerr is not visible to queue.h, namely to the
inline function getmlq. Here is possible solution at XENO_ASSERT level.

As seen in http://ngiger.dyndns.org:8011/tqm_f/builds/30/step-prep_bb/0
Exec in /var/buildbot/slave/tqm_f/xenomai: 
scripts/prepare-kernel.sh --arch=ppc --adeos=ksrc/arch/powerpc/patches/adeos-ipipe-2.4.25-*.patch --linux=/var/buildbot/slave/tqm_f/linux
Then in http://ngiger.dyndns.org:8011/tqm_f/builds/30/step-cfg_kernel/0
/var/buildbot/scripts/configure.sh /var/buildbot/configs/TQM860L_defconfig 
CROSS_COMPILE=powerpc-860-linux-gnu- ARCH=ppc
and finally the build with 
make --jobs=4 uImage modules
The http logs also show all environment variables (e.g. CROSS_COMPILE, PATH).

You can navigate between the different builds and buildsteps on 
http://ngiger.dyndns.org:8011/. I tried to make all steps transparent to the 
observer, to enable them to verify themselves all the build step. If you are 
unable to reach this site please tell me so. I updated my apache2 server and 
since this time the proxy/reverse proxy form 
http://ngiger.dyndns.org/buildbot to http://ngiger.dyndns.org:8011/ does not 
work anymore (but that is another problem I am investigating).

I did not change my Buildbot master setup since December 4. The 
prepare_slave.rb was updated on December 3
I updated today the TQM860L_defconfig to enable more CAN drivers etc, but that 
didn't change the error.

Build 28 (revision 1920) completed without any problem on December 6, and the 
build on December 7 (revision 1930). All these build are full build, meaning 
that all the build directories get removed before starting the 
prepare_kernel.sh

Did you also clean rebuild?

Is there somewhere a missing include?
I see that include/xenomai/nucleus/pod.h has 
#define xnlogerr(fmt,args...)  xnarch_logerr(fmt , ##args
But grep finds xnlogerr in the following object files
kernel/xenomai/nucleus/xeno_nucleus.o.
kernel/xenomai/nucleus/built-in.o.

Thanks. I applied the patch and the TQM860L compiled cleanly.

Why didn't you apply your patch? It solved my problem and I don't see any risk 
why you shouldn't apply it and didn't see any objections on this mailing 
list.

A more general change also fixing this issue has been committed to the
trunk.
