Description Justin 2024-06-27 13:33:06 UTC

SUMMARY

After working successfully for a few days, digikam fails to start entirely. When opening the program, it appears to start and then freezes immediately.

STEPS TO REPRODUCE
1. double-click "digikam.app" in /Applications, or run /Applications/digiKam.org/digikam.app/Contents/MacOS/digikam from the terminal

OBSERVED RESULT
digikam never opens a window, the digikam icon in the system dock bounces forever and needs to be force-quitted.

EXPECTED RESULT
Digikam opens a window and can be interacted with

SOFTWARE/OS VERSIONS
macOS: 14.1.1

ADDITIONAL INFORMATION
Terminal output:

[stays here apparently forever]

Presumably this is a configuration issue of some sort, but I'm not sure what to do next to debug this/restore digikam to a working state.

Created attachment 171092 [details]
digikam_systemrc

This is the typical point where the log stops when there is a problem opening a window due to openGL. Copy the "digikam_systemrc" attached here to the root where the digikamrc file is located. It should be "~/Library/Preferences/".
Test whether digiKam starts now.

Same behavior. The digikam_systemrc file was there, containing:

[System]
disableOpenCL=true
useHighDpiPixmaps=false
useHighDpiScaling=false

which I replaced with

[System]
softwareOpenGL=true

And then I reran :
$ QT_LOGGING_RULES="digikam*=true" /Applications/digiKam.org/digikam.app/Contents/MacOS/digikam debug

Getting the following output:
The available OpenGL surface format was either not version 3.2 or higher or not a Core Profile.
Chromium on macOS will fall back to software rendering in this case.
Hardware acceleration and features such as WebGL will not be available.

It looks like there may also be something wrong with OpenGL?

Comment 3 Maik Qualmann 2024-06-27 18:18:16 UTC

Ok, then set the entry to false, because by default it is not activated.

[System]
softwareOpenGL=false

Maik

Comment 4 Justin 2024-06-28 00:33:51 UTC

With 

[System]
softwareOpenGL=false

I get similar debug output:

$ QT_LOGGING_RULES="digikam*=true" /Applications/digiKam.org/digikam.app/Contents/MacOS/digikam debug
digikam.widgets: Breeze icons resource file found
digikam.widgets: Breeze-dark icons resource file found

digikam.general: Loaded Qt ECM translations "en" from catalog "kcoreaddons5_qt"
digikam.general: Loaded Qt ECM translations "en" from catalog "kwidgetsaddons5_qt"

Now with the absence of complaints about OpenGL.

@Justin

Please try the new 8.5.0 pre-release PK installer for MacOS Silicon (arm64) available here:
