[Buildroot] [PATCH 0/3 v2] toolchain/external: add Linaro 2014.11 (branch yem/toolchain-linaro-2014.11)

[Yann E. MORIN]

Hello All!

This series introduces the Linaro 2014.11 toolchains, for ARM (LE and
BE) and AArch64.

See the commit log of patch 1 for the gory details... :-/

ARM (LE) toolchain was tested with a minimalist setup, based on
qemu_arm_vexpress_defconfig, with just a switch to use EABIhf and this
toolchain (rather than the default EABI and internal toolchain), while
the AArch64 toolchain was tested in a similar way, based on
qemu_aarch64_virt_defconfig.


Changes v1 -> v2:
  - remove stray backup file


Regards,
Yann E. MORIN.

[Buildroot] [PATCH 1/3 v2] toolchain/external: add Linaro ARM 2014.11 ARMv7 EABIhf

[Yann E. MORIN]

This toolchain has a kind of hstory of its own... ;-(

First released in November 2014, it was completely broken, and Thomas
opened a bug report. Here's the story (for reference):
    https://plus.google.com/+ThomasPetazzoni/posts/SjFkrX3ow5M
    https://bugs.linaro.org/show_bug.cgi?id=862

since then, the release has been re-done, and the issue reported above
has been fixed. This makes that toolchain almost usable by Buildroot,
with just a few little nits:

  - it is available only for x86_64 hosts

  - the toolchain is split in three parts:
    - the main archive, with the tools and a minimalist sysroot with
      just the strictly required stuff (e.g. just the C library and most
      libs as static libs, i.e. no shared libs but libc.so)
    - a secondary archive, with the complete sysroot , duplicationg most
      previously existing files in the minimal sysroot, above
    - a tertiary archive, with the 'runtime' content (whatever that
      could mean...); that one seems completely unnecessary for
      Buildroot.

  - the sys/types.h headers from the main sysroot is correct, while the
    one from the secondary archive (thus overwriting the main one) is
    broken, as it removes the definition of caddr_t (why? WHY?).

  - there's a stray backup file for libstdc++

So, add this new toolchain with three post-extract hooks, one to extract
the secondary, sysroot archive, the second to restore sys/types.h to a
useable state, and the third to remove the backup file.

(Note: we're doing it in three hooks, because the cleanup hook is
different for the AArch64 toolchain, coming soon...)

Can you report this bug to the Linaro folks?

I already reported the stray backup file issue, but as part of my
original bug report. Maybe we should report it as a separate bug.

For Linaro toolchains, we've stopped adding version-specific Config.in
options. At any given time, we support only one Linaro toolchain, under
the option BR2_TOOLCHAIN_EXTERNAL_LINARO_ARM.

No comma between 'archive' and 'contains'.

Maybe be more specific here about what is being done rather than just
"let's fix the breakage".

ACK, will do.

ACK, will do.

Well, because the 2014.11 is kinda new and a bit broken so far, I wanted
to keep the 2014.09 as a backup, in case I missed issues with 2014.11.

I was able to build quite a lot of stuff with it, like the full Kodi
suite and the whole of Qt5, but QtWebKit, which should exercise the
compiler pretty well, but there might still be issues lurking around.
Hence adding it instead of replacing.

But if you really want we replace the existing one, I'm OK.

Well, it means the set of files in the sysroot archive is not a superset
of the sysroot files of the main archive:

  - main archive's sysroot:       [----------------]
  - secondary archive's sysroot:       [-----------------------]
  - intersection:                      [-----------]
  - exclusion:                    [----]           [-----------]

Thanks! :-)
