--- Comment #1 from ocumo <kxk-ocumoatbugs...@lugosys.com> --- WORKAROUND I have been able to create a WORKAROUND until this bug is fixed. As stated in the error message, the gmic_krita_qt program fails to find some library, most likely due to an issue with environment path. Follow these steps: 1. Locate the libqxcb.so file in your system. In an Kubuntu installation, this file is in your qt5 installation directory, i.e. in: /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so (If wouldn't have that file, then you have more problems, this workaround wouldn't apply.) 2. Change directory to the directory where you put your gmic_krita_qt file. Once there, create a directory 'plugins' and then inside that directory, create a 'platforms' directory, with this command: (you have to be already in the gmic_krita_qt's directory): mkdir -p plugins/platforms 3. Copy the libqxcb.so file into the platforms directory, like so: cp /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so plugins/platforms/ (again: you are issuing this command from the directory where gmic_krita_qt is) 4. In the same directory as gmic_krita_qt, create a text file named 'qt.conf' with this content (two lines): [Paths] Plugins = plugins 5. After saving the qt.conf file, you can now restart Krita. Open an image file and run the G'Mic filter. It should work now. DONE. Summary: You need to have this directory structure where you have the gmic_krita_qt file: $ tree . ├── gmic_krita_qt ├── plugins │ └── platforms │ └── libqxcb.so ├── qt.conf └── README ...where: a) 'gmic_krita_qt' and 'README' were extracted from the downloaded GMic zip b) the 'qt.conf' file contains the above mentioned lines, and c) you have created the 'plugins/platforms' directories and copied the libqxcb.so file in the 'platforms' directory. -- You are receiving this mail because: You are watching all bug changes.
