Description Kim Nilsson 2024-08-29 21:20:10 UTC

When the gui flag is enabled and --with-qt=6 is passed to the configure script, it looks for the package's required Qt libraries. These are as follows:
Qt6Core Qt6Gui Qt6Help Qt6Network Qt6OpenGL Qt6OpenGLWidgets Qt6PrintSupport Qt6Widgets Qt6Xml Qt6Core5Compat

If any one of these are missing, the GUI functionality is silently disabled and the build still succeeds. If the installed octave binary is run with the --gui argument, it refuses to start with the following message:
octave: GUI features missing or disabled in this build

In my case the missing library was Qt6Core5Compat, which is provided by the dev-qt/qt5compat package which is not a dependency of the ebuild.

I copied the ebuild to my local tree and added dev-qt/qt5compat after the line with dev-qt/qtbase and rebuilt the package. It pulled in dev-qt/qt5compat after which the configure script was satisfied and the GUI was re-enabled.

Reproducible: Always

Steps to Reproduce:
1. emerge =sci-mathematics/octave-9.2.0
2. octave --gui
Actual Results:  
The merge is successful, octave doesn't run when --gui is provided.

Expected Results:  
The merge is successful and octave displays the gui when --gui is provided.
