prolly fc40 specific runtime issue: some gtk2 module is not installed ? if not available then try build without gtk2-devel and gtkmm2-devel installed.

[topazus]

some gtk2 module is not installed ?

Do you know what gtk2-related packages missing? Maybe here is the packages about gtk2 on my machine.

❯ rpm -qa | grep gtk2
libcanberra-gtk2-0.30-32.fc39.x86_64
adwaita-gtk2-theme-3.28-17.fc39.x86_64
gtk2-2.24.33-15.fc39.x86_64
ibus-gtk2-1.5.29~rc2-5.fc40.x86_64
gtk2-devel-2.24.33-15.fc39.x86_64

if not available then try build without gtk2-devel and gtkmm2-devel installed.

Ok, I will try this.

With the build of turning off the options of CONFIG_LV2_UI_GTK2 and CONFIG_LV2_UI_GTKMM2, the executable can be run, but it appeared the following error:

[rncbc]

forgot to run real jackd(bus) or fake pipewire-jack (pw-jack) substitution?

otherwise the message box says it all.

[2-www]

i have the same error in flatpak, can this be run without rebuild?

i tried flatpak run --env=QT_QPA_PLATFORMTHEME=qt6ct, as in the last linked issue, but the error is the same
