[Xenomai] Compiling xenomai-3

[Xenomai] Compiling xenomai-3

[Leopold Palomo-Avellaneda]

Hi,

I'm trying to compile xenomai-3.x series using next branch from git.

I'm trying to use the "debian" method to build the kernel, using the make-kpkg 
and the instructions proposed in the web page. However, I got with an strange 
problem not found in 2.x.

make[2]: Entering directory '/srv/packages/xenomai/linux-3.16'
scripts/kconfig/conf --oldconfig Kconfig
init/Kconfig:1926: can't open file "arch/x86_64/xenomai/Kconfig"
scripts/kconfig/Makefile:33: recipe for target 'oldconfig' failed
make[3]: *** [oldconfig] Error 1
Makefile:545: recipe for target 'oldconfig' failed

Any idea?

Leopold

the ARCH variable is probably defined in the environment to x86_64, but
for compiling the kernel, ARCH should be x86 (there as not been an
arch/x86_64
directory since sometime early in the 2.6 branch).

But I didn't have this problem compiling 2.6.4. Any idea to solve it?

export ARCH=x86 ? or is something of specific of xenomai?

I do not know. Another possibility is that prepare-kernel.sh is broken
for --arch=x86_64 or something. Do what the makefile do, step by step
to understand what happens.

it fails when I execute the debian command. But it works when I just execute  
make bzImage modules.

So, I don't think that it could be prepare-kernel.sh script

Which kernel version and which make-kpkg version?  Could be the make-kpkg
is too old for the kernel version.

I hadn't noticed xenomai support for 3.16 yet either, only 3.14, but I
haven't checked lately.

The I-pipe patches for 3.16 are in the GNA download area.
We have not released a version of Xenomai with it yet, but they exist.

I am just trying to answer clearly your claim, and repeating what has been
exchanged on another mailing list (which you do not seem to read).
But the I-pipe patches are in the GNA download area for everyone to see. It
is all in the open. If you do not know whether the patch exists, simply look
in the download area before insinuating that the patch does not exist.

Well I did mention I hadn't checked lately.

That's ok. C'mon guys, please relax a bit. I'm the one who sends the
patches to the download area, and as a matter of fact, I'm not
announcing them. So I'll announce them on this mailing list from now on,
which should help.

We have x3 -rc3 pending, some work remains to release it. Let's use our
time efficiently.

Well,

some test:

scenario:

kernel: linux-3.16
ipipe-patch: ipipe-core-3.16-x86-1.patch (it's the same in the adeos repos 
that xenomai repo, I checked it ;-)
xenomai-3.git, checked today branch "next".
chroot with jessie/sid environtment. updated today.

decompress kernel and execute in the linux dir:

../xenomai-3.git/scripts/prepare-kernel.sh --linux=. --
ipipe=../xenomai-3.git/kernel/cobalt/arch/x86/patches/ipipe-core-3.16-
x86-1.patch --arch=x86


- copy an old config and do:
make oldconfig (ok)

- CONCURRENCY_LEVEL=8 CLEAN_SOURCE=no fakeroot make-kpkg --verbose --initrd --
append-to-version -xenomai-3.0.0 --revision 1.0 kernel_image kernel_headers

fails with this message:

the file init/Kconfig has in that line

if XENOMAI
source "arch/$ARCH/xenomai/Kconfig"
endif

if I put here x86 (instead of $ARCH that was x86_64), it seems it compile and 
build the packages.

Please could you put the contents here that match with the contents of the 
directory: linux-x.y.z/arch?

Also, I would like to say, that a folder with the name x86_64 was created by 
make-kpkg.


Best regadrs,

Leopold
