Updating Fedora 38 to 39 breaks octave-8.3.0 (precompiled from Fedora) and octave-8.4.0(compiled from source). When I run $ /usr/bin/octave --gui (octave-gui:1632543): Gtk-WARNING **: 18:58:40.527: Theme parsing error: <data>:1:0: Expected a valid selector and the window hangs. Reproducible: Always Steps to Reproduce: 1./usr/bin/octave --gui 2. 3. Actual Results: octave window is unresponsive Expected Results: Show octave console See attached stack trace.

Hmm. Well, rawhide has 8.4.0 already... if we have to rebuild anyway, might as well bite the bullet and upgrade?
Building 8.4.0 for fc39 now at https://koji.fedoraproject.org/koji/taskinfo?taskID=109076812
Just pointing out that it seems to me that this is actually not a bug in octave-8.3.0 but that it is a bug in qt5-qtbase-5.15.11-3.fc39.src.rpm. Changing the component field to that.
FEDORA-2023-289ef7a458 has been submitted as an update to Fedora 39. https://bodhi.fedoraproject.org/updates/FEDORA-2023-289ef7a458

Oh, perhaps I misunderstood your comment #2 — are you saying you had to _patch_ qt5-qtbase-5.15.11-3.fc39 (beyond the original contents of the package)? And when you said, "...and rebuilding", did you mean rebuilding Octave, or rebuilding qt5-qtbase? If the problem is in the current qt5-qtbase-5.15.11-3.fc39 package, then the octave-8.4.0 build I just did against it is probably equally broken.
Yes. The patch is in comment #2. I patched the file SOURCES/0014-QGtk3Theme-Improve-fixed-font-delivery.patch in qt5-qtbase-5.15.11-3.fc39.src.rpm, rebuilt the rpms and then reinstalled the rpms. The problem showed up with octave-8.3.0 but is due to the missing initial "*"in the CSS string in the function "QFont QGtk3Interface::font(QPlatformTheme::Font type) const" in the file "src/plugins/platformthemes/gtk3/qgtk3interface.cpp". Apologies for the confusion.
FEDORA-2023-289ef7a458 has been pushed to the Fedora 39 testing repository. Soon you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2023-289ef7a458` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2023-289ef7a458 See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates.
This problem is still occurring .. is there a work around to be able to use the GUI?
Created attachment 2011083 [details] Build development version of octave-9 The next version of octave updates to qt6. It should be released soon. If you can't wait, try building a local Fedora version with the attached script. You may have to install a lot of dependencies first.
In the uploaded script, for the "octave --gui" version, you'll need to remove the line "--disable-java \" from the octave "configure" command.
Michael, try running your version of Octave as root.
yes, this actually worked..
Created attachment 2011310 [details] Script to build/install octave-9 to /usr/local (run as regular user; uses sudo) Ugh, I didn't realize the Qt5 CSS issue wasn't going to get fixed in F39, sorry about that. I'll back this down from "ON_QA" status, and see what I can do about addressing it. Perhaps a local Qt style sheet. When Octave 9 is released, we would be able to upgrade F39, since the current package is broken — in fact, we could upgrade it now, building from the development sources; I'll try to find some time to explore that. In the meantime, though, a local build is the quickest solution I'm afraid. Thanks for providing that script, @robertjenssen.au. I've gone through it and updated the install and privileged commands to use sudo, rather than having to run the entire build as root. Feels a bit safer. Updated version attached. (I didn't remove --disable-java.)
Created attachment 2011311 [details] Script to build/install octave-9 to /usr/local (run as regular user; uses sudo) And, of course, I immediately caught an error in my script. Attaching a fixed version.
