GUI does not open in carla and ardour

[zettberlin]

I have created symlinks in /usr/local/lib/calf that point to all files, that start with "lib" with names without that prefix:

` lrwxrwxrwx 1 root root 9 Jul 9 14:10 calf.a -> libcalf.a

lrwxrwxrwx 1 root root 10 Jul 9 14:08 calf.la -> libcalf.la

lrwxrwxrwx 1 root root 15 Jul 9 14:09 calflv2gui.a -> libcalflv2gui.a

lrwxrwxrwx 1 root root 16 Jul 9 14:10 calflv2gui.la -> libcalflv2gui.la

lrwxrwxrwx 1 root root 16 Jul 9 14:10 calflv2gui.so -> libcalflv2gui.so

lrwxrwxrwx 1 root root 10 Jul 9 14:08 calf.so -> libcalf.so

... ` Thus the plugins load and work in both Carla and Ardout 6.8 but alas: The GUIs do not. I can set parameters using the generic host GUI but the shiny custom UI does not load.

Its Ubuntu Studio 20.04, got another machine with the same OS where a ca. 2 months old git master works perfectly well.

autogen.sh tells me, that everything is "yes" with Plugin GUIs

I also tried the "fixed UI" branch from @puleglot same result...

Same here on McOS (Catalina) in Ardour 6.8. Calf installed by Homebrew. Everything works, except the Gui.

Having same problem with Debian Sid + Reaper latest versions + Calf from Debian repo. Pugins work but no UI on DAW, only the generic controls, however UI does show when loading plugins on calfjackhost

This issue is still happening using latest release of Carla. Have anyone managed to find a workaround?

The error I see in Carla logs is

Gtk-Message: 13:14:28.348: Failed to load module "pk-gtk-module"
[carla] Failed to load UI binary, error was:
/usr/lib64/lv2/calf.lv2/calflv2gui.so: cannot open shared object file: No such file or directory

[mickaelistria]

OK, solution was simple for me: sudo dnf install lv2-calf-plugins-gui
