            Bug ID: 15979
           Summary: wpewebkit build failing (for ARM A15/NEON)
           Product: buildroot
           Version: 2024.02
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: buildroot@heine.tech
                CC: buildroot@uclibc.org
  Target Milestone: ---

Since bumping to 2024.02 the build for wpewebkit is failing. Last BR version I
worked with was 2023.08.3 (where it worked) so I can't tell about the ones in
between.

To me this looks like a missing dependency. I tried adding a dependency on
host-libyaml for wpewebkit but it didn't help. Any Ideas?

You need to add the host-libyaml dependency to host-ruby (instead of wpewebkit)
and re-build host-ruby:

--- Comment #2 from Michael Nosthoff <buildroot@heine.tech> ---
Thanks Peter! That fixes the build for me.

But would this approach be feasible to fix this? Or should we do something like 

ifeq ($(BR2_PACKAGE_HOST_LIBYAML),y)
HOST_RUBY_DEPENDENCIES += host-libyaml
endif

in the ruby.mk and then depend on host-libyaml in the wpewebkit.mk?

--- Comment #3 from Peter Seiderer <ps.report@gmx.net> ---
There is no BR2_PACKAGE_HOST_LIBYAML option (yet) in buildroot (not all host
enabled packages have a proper configure setup, most/many are simply enabled by
a direct dependency statement and host-libyaml and host-ruby are among of
them), either the above patch/hack is acceptable (despite the additional
host-libyaml dependency for all other host-ruby users qt5webkit, webkitgtk,
ruby) or host-ruby is extended to an real host package (Config.in.host,
BR2_PACKAGE_HOST_RUBY and BR2_PACKAGE_HOST_RUBY_YAML_SUPPORT)...

--- Comment #4 from Thomas Devoogdt <thomas.devoogdt@barco.com> ---
I came across the same problem while preparing the bump to webkitgtk-2.44.0:

https://patchwork.ozlabs.org/project/buildroot/list/?series=401571

See patch about ruby:

https://patchwork.ozlabs.org/project/buildroot/patch/20240403171424.44580-1-thomas@devoogdt.com/

I independently had the same comment about how to add it properly.
Anyway, webkitgtk is a quite big fish to compile, so the additional few
seconds to get host-libyaml is perhaps not worth the additional trouble.
