With Mutter new API | undefined symbol: meta_compositor_flash_screen

With Mutter 3.29.4

gala: symbol lookup error: /lib64/libgala.so.0: undefined symbol: meta_compositor_flash_screen

I know that elementary isn't supposed to support Mutter 3.30, specially when there is not even a 3.30 release yet, but I'm mentioning the issue since @ricotz has already pushed this: be1729d

also the libs are now

'--pkg', 'libmutter-3',
'--pkg', 'mutter-cogl-3',
'--pkg', 'mutter-cogl-pango-3',
'--pkg', 'mutter-cogl-path-3',
'--pkg', 'mutter-clutter-3',

Guess there are already some issues about gnome 3.30. Same story on Arch Linux, tried cherry-picking ricotz' branch on top of master, but the build fails almost immediately on undefined Meta.Screen: https://paste.xinu.at/R6OI/

[alex285]

@alucryd yeap, Meta.Screen is actually dropped on Mutter 3.30. On elementary Fedora build Copr, they package Mutter 3.28 in parallel with Mutter 3.30 in order to make it work

[alucryd]

I see, thx for the heads up. It's not really arch-like to provide older versions though, we only do so if absolutely necessary. I'll consider it if users start a riot about gala not building anymore.

[alex285]

@alucryd just for reference if you're going to push on Arch

here is the Copr
https://copr.fedorainfracloud.org/coprs/decathorpe/elementary-nightly/

here's how they patch Gala Mutter 3.28
https://github.com/decathorpe/elementary-nightly-rpms/blob/8abba864268f26efcc72c395841d49e33c03cbb1/specs/gala/gala.spec#L35

obviously they keep original Mutter from Fedora repos, and @decathorpe additionally packages a mutter328 only for Gala

@ricotz I don't want to be pesky, but have you got any idea when you'll be able to look into mutter 3.30? I see your dedicated branch has disappeared. Packaging mutter 3.28 on Arch Linux is a real pain, it depends on other libraries that are also too recent and also need to be packaged alongside their most recent version.

[alucryd]

I didn't realize the API had changed that much, I gave porting a try but I'm in way over my head. I generated the latest libmutter VAPI though in case you're interested: https://paste.xinu.at/TqZW7/

I'm in the very same situation, as I'm packaging Pantheon dependencies for Solus distribution, which actually upgraded mutter package to 3.32 series, breaking the ability to build gala, pantheon-greeter, pantheon-applications-menu and wingpanel (and many others, consequently).
Are you planning to add support for mutter newer versions?

Are you planning to add support for mutter newer versions?

Should happen before the end of the year but no estimate can be given at that time

[alex285]

im closing it, since @tintou already fixed that at #566
