[Xenomai] next xenomai release

[Xenomai] next xenomai release

[Gilles Chanteperdrix]

Hi Roland,

the next release of Xenomai should happen soon. The changes which may
impact the Debian packaging are:
* changes in the configure script option, actually simplifications;
- --enable-smp is no longer needed on x86, powerpc and arm
- as a reminder, on the ARM architecture, passing --enable-arm-arch or
--enable-arm-eabi is not needed either since 2.6.0, so in fact, no
option is needed when running the configure script for the arm
architecture. Passing the correct -march to the CFLAGS is recommended to
generate optimized code, but starting with the future release, is not
even mandatory.
- this release support ARM user-space built with the thumb instruction
set (-mthumb added to the CFLAGS, or enabled by default in the toolchain
configuration)
* small changes in the documentation, we introduced some asciidoc (I
would have wanted to also move the manual pages to asciidoc, and update
them, but it will be for the next release), the visible change is that
an HTML version of the README.INSTALL and TROUBLESHOOTING files are now
installed by the "make install" command in the html directory.

I would also like to setup an apt repository to provide pre-compiled
kernels, at least for the x86 architecture (say, for instance, i486 UP,
i686 SMP, x86_64 SMP), as well as the user-space packages, so, would be
interested in documentation URLs.

Regards.

Thank you for the note! This really simplified my update in Debian.

I just tested a snapshot from git.xenomai.org (using xenomai-head.git
and building a test tarball with ./configure && make dist) - looks good
so far.

For setting up an apt-repository, I recommend using the "reprepro"
package (from Debian) which helps setting up and maintaining an apt
repo. You just need to provide individual .deb, .changes, or .dsa files
on the command line and it adds them automatically to our new repo. Just
ask if you need assistance here.

For building the packages for this repo, you ideally just build the
default Debian packages with dpkg-buildpackage and follow the
instructions in

/usr/share/doc/linux-patch-xenomai/README.Debian

to build kernels.

There is also

http://www.xenomai.org/index.php/Building_Debian_packages

I hope this answers your questions?

Looking forward to the xenomai release.

Thanks in advance,

Roland

well,

there's a bug, and I must admit that I don't know if it's deliberated (*) or 
not.  This bug comes from some time ago. In the /ksrc/arch/x86/patches 
directory, there's a patch for the 3.2.21 kernel:

ipipe-core-3.2.21-x86-1.patch

this patch, in the build process is not included in the root directory: the 
/scripts/prepare-patch.sh script executes:

find $xenomai_root/ksrc/ -name "adeos-ipipe-2.6.*-$supported_arch-*.patch" 

that is incorrect because the ipipe-core* patch is not found. The correct one 
would be:

----------------------------------------------------------------
$ diff -u xenomai-2.6.git/scripts/prepare-patch.sh xenomai-
head/scripts/prepare-patch.sh

----------------------------------------------------------------

so, please could you clarified if you put this patch or not?


(*) Deliberated in the way that maybe it's not sufficient stable yet to 
include it and upstream prefers to not include it by default.

I agree. 

Also, I can mirror the repo at my University.

I guess this is a reverse patch?

I'm not too sure about the official patch naming, but generally, patches
should be included, yes!

So this bug should be fixed, if it is a bug.

Thanks,

Roland

yes, the order is inverse. Sorry.

OK, should be fixed. Can't find the change in xenomai 2.6.2, unfortunately.

I am working on generating the debian packages now, there are a few
other issues, I will push a commit when they are fixed, and maybe
another xenomai release.

[Xenomai] Another dpkg build issue for Xenomai 2.6.2

[Jeff Webb]

When building dpkgs on Ubuntu 12.04, this line in the debian/rules file gives me trouble because there are no longer any adeos-ipipe-*.patch files for the x86 architecture:

cp adeos-ipipe-*.patch $(CURDIR)/debian/linux-patch-xenomai/usr/src/kernel-patches/diffs/xenomai

As a workaround, I did this before building:

touch ./ksrc/arch/x86/patches/adeos-ipipe-2.6.0-x86-dummy.patch

Hi Roland,

it turned out that a little more work was needed to check whether the
release was ready for generating debian packages, as, you may have
follow, the 2.6.2 release was completely broken in this regard.

The information on this page is outdated, as support for dkms was
removed from the xenomai package, so, the "apply" script does not exist.

Thanks for the pointers.
