Ok, I'll see if Philip can fix this. Hopefully it's just a forgotten #ifdef someplace.

so it looks like there is a dependency...

Thanks for tracking this down.  Yes, the LV2 stuff can use gtk2, but it doesn't need it.  You should be able to install lilv-devel without gtk2-devel and that might work.  Let me know how it goes if you try it.

  Note: A fresh clone shouldn't be necessary.  Just delete your build directory, create a new one, switch into it and run cmake again.

Hi Chuck,

I have the same problem with the compiled 24.06 version on Fedora 40.

I compiled the 23.12 version and it runs fine.

The problem is from the LV2 plugin support which is using GTK2. I
don't think there's a way to disable LV2 plugin support at compile
time.

If I find a solution I will post it here.

RG 21.12 runs ok on this system (lying around in /usr/local/bin)

Rosegarden version: 21.12 ("Cloud Nine")
Build key: ac38e2622f (21.06-24-gb9da2db9d)
Built against Qt version: 5.15.2

Current version info is:

Rosegarden version: 24.12 ("Incredible")
Build key: 442818511e (24.06-1-gf91b7e227)
Built against Qt version: 5.15.13

How would I be "requesting the gtk widgets"? I am not aware of having,
or how I would have, done so...

I assume that my RG preferences would be applied the same to both of the
above versions?

TIA

Chuck.

Just some limited searching seems to indicate that the "gtk" widget
style was dropped around Qt 5.7 or so.  Maybe you're running a newer
version of Qt and you are requesting the gtk widgets?

   See post #36.

   All the trails are from 2016/2017, though.  Not sure they are
relevant today.

Rosegarden won't run at the moment.

The problem seems to be something to do with "GtkWidget" (see below).

24.06 built fine from git source.

I have recently upgraded to fedora 39 and this is probably the first
time I have tried to

run RG since. Same result on a similar/identical system.
