Supported host distro updates

Hi all,

With the release coming up fairly soon, it's time to look at updating our supported distro list. Currently we have the following (in meta- yocto/conf/distro/poky.conf):

SANITY_TESTED_DISTROS ?= " \
            Yocto (Built by Poky 7.0) 1.2 \n \
            Ubuntu 10.04.4 LTS \n \
            Ubuntu 11.10 \n \
            Ubuntu 12.04 LTS \n \
            Ubuntu 12.04.1 LTS \n \
            Fedora release 15 (Lovelock) \n \
            Fedora release 16 (Verne) \n \
            Fedora release 17 (Beefy Miracle) \n \
            CentOS release 5.6 (Final) \n \
            CentOS release 5.7 (Final) \n \
            CentOS release 6.2 (Final) \n \
            Debian GNU/Linux 6.0.4 (squeeze) \n \
            openSUSE 11.4 \n \
            openSUSE 12.1 \n \
	    "

I think we should drop at least Fedora 15. What do we want to do with CentOS? I've been using 6.3 here on my build machine for some time with no ill effects. I believe we have some interest in preserving 5.x; should we be adding 6.3 and removing 6.2? What about the rest?

Cheers,
Paul

The latest stable is 6.0.5, so someone keep up to date with Debian Stable will get the warning (it's just a roll-up release of security and critical fixes).

openSUSE 12.2 was released on September 5th. I have been using it since around then and haven't found any issues. Is there some defacto test I can run to definitively say 12.2 works fine with Yocto?

IIRC, when we tested the 12.2 pre-release we found we were unable to support it due to the following bug:

https://bugzilla.yoctoproject.org/show_bug.cgi?id=2201

If that is definitely fixed and builds run through OK, we should be able to add it to our host distro tests and declare it supported.

As you mentioned, this was on a pre-release milestone, 6 months before the final release.

I just did a fresh test of the quick-start guide and saw a bunch of warnings, but the build itself completed successfully:

Build Configuration:

BB_VERSION        = "1.15.3"
TARGET_ARCH       = "i586"
TARGET_OS         = "linux"
MACHINE           = "qemux86"
DISTRO            = "poky"
DISTRO_VERSION    = "1.2+snapshot-20120924"
TUNE_FEATURES     = "m32 i586"
TARGET_FPU        = ""

So unless those warnings are host-related I think it's safe to say openSUSE 12.2 has a base level of support. Is there any definitive test that anyone can suggest?

FWIW I have been build testing on (to be) Ubuntu 12.10/32bit without any issues.

Will want to ensure this is updated to the correct Yocto version also, maybe both N and N-1.

Sau!

I do testing on

CentOS release 5.8 (Final)

and

Fedora release 13 (Goddard)

I'm even fixing issues with libx11 now on CentOS 5.x

-M

OK, so do we keep 5.6 / 5.7 or remove them in favour of 5.8?

I think this is probably too old for us to be declaring support for, since it has been unsupported upstream for some time now.

Cheers,
Paul

I don't think you can... each of these present different issues I've found and fixed along the way.

This has been working for me for a while (with a lot fewer issues to fix than CentOS 5.x) unless I'm missing something, I don't think it's too old.

-M

OK, I'll leave them in for the moment.

I consider it too old because of its upstream support status, but also because broadly we commit to supporting N and N-1 (and usually N+1) where N is the most recent release of the distribution. Fedora 13 would be N-4.

Not having Fedora 13 (or any other distro or distro version, for that matter) in this list does not mean that you can't continue to use it, nor does it necessarily mean that we won't take patches to fix support for it should it break.

Perhaps a better solution here is to have two lists. An officially tested and supported along with a known not to work list.
