[libcamera-devel] Fwd: [autobuild.buildroot.net] Your daily results for 2020-06-23

Wed Jun 24 10:27:18 CEST 2020

Hi all (libcamera, and buildroot lists joined).

Buildroot build-bots are reporting some compilation failures for libcamera.

The Nios2 one is some architecture-specific 8-byte alignment issue?
I'd be tempted to disable builds on Nios2...

Then there are also two build failures for x86_64 and mipsel64...

Looks like we're hitting compile warnings in external glib, which we're
treating as errors ;-(

That's annoying...

In terms of 'buildroot', I expect we could wait for that to be 'fixed'
upstream in glib-2.0 (this build was using 2.64.3)

Generally I'd really like to keep -Werror enabled, as it will help catch
issues faster, and specifically keep our build warning clean.

I guess we can't easily say '"But ignore warnings in externally included
files"' ...
