[Buildroot] Analysis of build results for 2016-05-23

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello,

The release is approaching, the build results are getting better, so
let's try to make some additional work to make results even better.

On a total of 31 failures, we have:

 - 8 issues that are already resolved
 - 4 that have patches, some of which not completely ready
 - all the rest that remains to be investigated/fixed

>      powerpc |                 blktrace-1.1.0 | NOK | http://autobuild.buildroot.net/results/47dc536f613f958c52f3879411ba6fb3b861d6b4/

This is a toolchain/compiler issue, Gustavo is investigating.

>          arm |                 collectd-5.5.1 | NOK | http://autobuild.buildroot.net/results/24a35b63921cb9d747052f3bbfc3549ed20e18d7/

Those issues are resolved for the non-musl builds, thanks to the
rebuild of the toolchains with 4.5.5 kernel headers. The ARM/musl case
(first one here) still fails to build, though.

Fixed by the toolchain rebuild with 4.5.5 kernel headers.

I've investigated this one, and it's due to the fact that ffmpeg's
configure script adds both -mips64 and -mips64r6 to the command line.
It can be trivially reproduced by doing:

thomas at skate:~/projets/buildroot (next)$ ./output/host/usr/bin/mips-img-linux-gnu-gcc -c pouet.c -mips64 -mips64r6
pouet.c:1:20: fatal error: limits.h: No such file or directory
 #include <limits.h>
                    ^
compilation terminated.
thomas at skate:~/projets/buildroot (next)$ cat pouet.c 
#include <limits.h>

Vincent, can you look into this one?

Would be solved by http://patchwork.ozlabs.org/patch/624244/, but I
still have some concerns about this patch.

Parallel build issue it seems.

Bernd proposed some patches, to which I replied with I believe a
better/more general solution.

Download problem, ignore.

We need a better variant of: http://patchwork.ozlabs.org/patch/569818/.

Not sure:

make[4]: *** [libirrecord.la] Error 1

It's happening on all architectures it seems:

musl build issue for LVM2.

Seems to be like a real timeout.

Alexey, this is a compiler issue on ARC, can you have a look?

> microblazeel |                 oprofile-1.1.0 | NOK | http://autobuild.buildroot.net/results/72494289e1ed8c5ce867444968331e63a00026d3/

I sent a patch to disable oprofile on Microblaze, but it didn't make it
through the list :-/

Seems like passing std=c++11 is needed.

I've investigated this one, and reported back to the developer who
originally contributed this package.

Linker bug. We should blacklist this toolchain and/or report the bug to
the binutils developers.

Bernd proposes to disable ustr/libsemanage on musl (which is fine for
me).

Bernd, Gustavo, do we have patches for this one?
