Ubuntu 24 Compatibility

[sacrispada]

Hey there.

I am trying to load some old projects in Ardour8 and I am facing some undefined symbol errors. The first one was related to libinstpatch (undefined symbol: g_once_init_leave_pointer). I downgraded it from libinstpatch-1.6-r2 to 1.6-r1 and that seems to have solved (this?) problem.

However, when trying to fire up the UI of a Calf Plugin, I get
suil error: Unable to open UI library /usr/lib/lv2/calf.lv2/calflv2gui.so (/lib/x86_64-linux-gnu/libatk-1.0.so.0: undefined symbol: g_once_init_enter_pointer)

Before I go on and download sources, compile and preload yet another previous version of libatk, I decided to come here and ask if this is a common problem with a simpler/easier solution. I am assuming that I might have to do that for several other libraries too.

Thanks in advance!

Ardour 8.4 Calf plugins [ERROR]: failed to instantiate LV2 GUI

Note that Calf will likely soon vanish from many GNU/Linux distributions as well. – A bit of background: Various GNU/Linux distros are dropping GTK2. This means that all software that still depends on it can no longer be packaged. Notably Debian is finally doing this, which affects all debian based distributions (Ubuntu, UbuntuStudio, AVLinux, KXstudio, …) Ardour was affected by this, which is which is Ardour 8.4 internalized the toolkit. This in turn breaks plugins that still rely on GTK2+…

Short version, CALF plugins are not likely to work.

Thank you for the explanation. What is currently the suggestion for a CALF replacement?

[Majik (Keith Milner)]

Airwindows, LSP Plugins, to name a couple.

Cheers,

I’ll try that, thanks. Since I’ll be restructuring all the plugins anyways, I’d be happy to take further suggestions which you guys might have on that front.

Are all LV2 plugins suffering from the GTK2 deprecation, or just CALF specifically? (honestly, I don’t remember what they use).

A short list: LSP, Airwindows, Antanas Bruzas, ApisonicLabs, Auburn Sounds, Audio Damage, Bertom Audio, BlueLab, brummer10, ChowDSP, Chroma DSP, Distrho Ports, Dougal-s, ElephantDSP.com, GSi, GVST, JClones, Jpcima, lkjb-plugins, MacFizz, MDA, Michael Willis, ReaPlugs, Semantic Audio, Signal Perspective, SocaLabs, Sonic Audio, SuperflyDSP, TAL Software, Thomas, Tin Brook Tales, ToneLib, Tukan, VennAudio, White Elephant Audio, x42, ZamAudio, ZL Audio.
With this CALF plugins are not needed for me.
But there are many more plugins from the collections on the respective sites.

No! Most of the LV2 plugins work well!

Well more specifically it is plugins that use GTK (Which never should have happened anyways really, programming technical reasons that searching for here will get you multiple threads about). So CALF and Invada IIRC and there are probably others out there that I can’t think of.

Thank you all for the plugin suggestions. It will take a long while before I can test all of them, so I’ll just keep the list nearby and take the time.

PS: I’ve been using ZamAudio for a while too, that’s pretty great!

Cheers!
