[Buildroot] Autobuilder update

[Thomas Petazzoni]

Hello,

Some autobuilder updates:

 - All the Buildroot pre-built external toolchains have been rebuilt
   with Buildroot 2016.02 + a few patches. To see which patches I'm
   using to build those external toolchains, see the branch at:

   http://git.free-electrons.com/users/thomas-petazzoni/buildroot/log/?h=br-ext-toolchain-fixes

 - The br-sh4-full configuration has been changed to actually use the
   Buildroot toolchain, and not the pre-built Musl-cross toolchain.

 - I've fixed the Free Electrons build server, which was no longer
   building anything since quite some time, due to a lack of disk
   space. This will help re-increase the number of builds done each day.

Let me know if there are other things that should be improved/changed
in the autobuilder setup (be it adding more toolchain configurations,
or other changes).

Thanks!

Thomas

Hi Thomas,

do we have a config for a buildroot x86 toolchain which lacks
BR2_X86_CPU_HAS_MMX? An empty defconfig file would be enough imho, the one
you get when you call "make menuconfig" in a fresh git checkout without
selecting anything and save this config, like: 

bernd at buildroot:~/buildroot/buildroot$ make menuconfig
(select nothing, just save the config)
bernd at buildroot:~/buildroot/buildroot$ make savedefconfig
BR2_DEFCONFIG=test cat test
bernd at buildroot:~/buildroot/buildroot$ cat test
bernd at buildroot:~/buildroot/buildroot$ 

I think such a config would be useful because lots of media packages
contain mmx specific code. 

Regards, Bernd

By default we use i586, right? So what you suggest is an i586 defconfig?

Now we have two options:

 - Use an internal toolchain configuration, which means that the
   toolchain is rebuilt everytime, and when we want on our side to
   reproduce the build failures, we also have to rebuild the toolchain.

 - Use a pre-built external toolchain.

I'm leaning twoards the second option. What do you think?

Best regards,

Thomas

It depends on how much we're otherwise testing the internal toolchain? I
agree that using an external toolchain is more efficient, but we should
imho do "some" builds with the internal toolchain on various archs as
well.

I recently also ran into these gmp/mpc/mpfr issues building a toolchain
at work (for the glibc dns issue) and had to spend some time to debug
and come up with a similar workaround as you did. I really think we
should include that patch in buildroot until we get the $ORIGIN rpath
stuff merged to save peoples time.

OK. So I'll submit such a patch.

I would also like to get a resolution for the toolchain wrapper usr/
issue. I proposed the patch in the thread I originally started, but got
no feedback so far (but I understand the issue is not the most pleasant
one to think about).

Agreed. We currently have the following internal toolchain
configurations tested:

br-arc-full-internal.config
br-arm-internal-full.config
br-microblazeel-full-internal.config
br-powerpc-internal-full.config
br-xtensa-full-internal.config

I can add some more if you have some suggestions.

Best regards,

Thomas

Perhaps this proposed br-i586-minimal.config?

Yeah, I haven't had time to look at it yet. I'll try to find time this
weekend.

I updated my instance yesterday evening. Thanks! :-)

In fact, updating your instance was not needed. The changes I made only
affect the .config files, which are re-downloaded every time a build
starts. So updating the autobuild-run script is not needed.
