[igt-dev] [PATCH v2 0/6] Fix musl/uclibc build

[Bernd Kuhls <bernd@kuhls.net>]

Hi,

this is v2 of my first patch series I am sending so please be patient ;)

Currently there are efforts underway to add a igt-gpu-tools package to
the buildroot project. Besides glibc buildroot also supports musl- and
uClibc-based toolchains. While testing the new package it turns out that
igt-gpu-tools does not build with other libc's out of the box, see
https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/issues/138

This patch series tries to solve the request from the bug tracker that
the void-linux patch is "splitted into some functional changes".

During build I added only those parts of the void-linux patch which were
needed to fix build errors, I quoted those errors in each patch message.
Besides that, due to my non-knowledge of C, I can not provide any more
information.

Notes added in v2:

Answering some reviews:

> Btw did you check against new igt sources, v1.28?

Yes, version 1.28 is used.

> While it fixes your build (?) it breaks igt build on current
> Ubuntu 22/x86_64, see:

I added a different fix hoping it does not break anything.

Changes:
- removed some includes from patch 0002 (Kamil)
- added a different fix in patch 0003 (Kamil)
- updated author of patch 0006
- added s-o-b of original author in all patches when needed

Regards, Bernd
