[Buildroot] [PATCH V3 0/4] Use only elfutils package to provide the libelf library

[Buildroot] [PATCH V3 0/4] Use only elfutils package to provide the libelf library

[Gregory CLEMENT]

Hi,

The libelf is currently provided by 2 packages libelf and
elfutils. The first package provides an old version of the libelf
which is no more compatible with a recent version of ltrace. Having
both libraries could lead to the link on the wrong one during the
build. It is what happened for ltrace.

To avoid this kind of issue, this patch set switch the dependency from
libelf to elfutils and finally removed the libelf package.

I built and fully tested ltrace on ARM.
I built and just ran avrdude on ARM.
I didn't build kexec-lite.

Thanks,

Changelog:
v1 -> v2:
- Propagated the dependencies from elfutils for kexec-lite and avrdude
- Fixed the subject of the avrdude patch
- Use the -D flag to generate the patch: only the mention of the
  deleted files is kept. This allows to have a very light patch but
  one will be able to apply the patch only by using git.

v2 -> v3:
- moved the config option of the libelf package to Config.in.legacy

Gregory CLEMENT (4):
  ltrace: Removes the libelf dependency
  avrdude: Depend on elfutils instead of libelf to get the libelf
    library
  kexec-lite: Depends on elfutils instead of libelf to get the libelf
    library
  libelf: Removes the package

[Buildroot] [PATCH V3 1/4] ltrace: Removes the libelf dependency

[Gregory CLEMENT]

The libelf is currently provided by 2 packages libelf and
elfutils. The first package provides an old version of the libelf
which is no more compatible with a recent version of ltrace. This
patch removes the dependency on the libelf package and only keep the
elfuils package which provides the accurate version of libelf for
ltrace.

It will also allow to remove the libelf package and to avoid conflicts
with two packages providing the same library.

At first, I was very surprised that an AVR-related package would be
unavaivlable for avr32. But that's not incoherent, in fact: this can be
used on the target to program an AVR (not avr32!) device.

That it does not work on avr32 is a pity, though... :-(

Anyway, acked.

Yann E. MORIN.

Same as for avrdude, we should update the toolchain options comment to
match.

[Buildroot] [PATCH V3 4/4] libelf: Removes the package

[Gregory CLEMENT]

The elfutils package provides a more recent version of the
libelf. Some packages such as ltrace need this more recent
version. Having two packages providing the same library leads to some
conflicts or dependency problems. For instance at the end we had only
one libelf.a when the 2 packages were selected.

Bye, Peter Korsgaard

[Buildroot] [PATCH V3 0/4] Use only elfutils package to provide the libelf library

[Thomas Petazzoni]

Jeremy, Wojciech,

As the original authors of the kexec-lite and avrdude packages
respectively, would you mind checking if the below patch series, which
removes the libelf package in favour of the libelf bundled with
elfutils does not break avrdude and kexec-lite ?

Thanks!

Thomas
