The reason why the above packages were bundled under qt6-masterpdfeditor was as a workaround for hardening incompatibilities. The upstream binary was compiled against Qt 6.4.2, which lacks the GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS flag that Qt 6.11+ enforces. Rather than downgrading the system Qt (which would break other packages and maintainability), we bundle these compatible versions locally in /opt/masterpdfeditor/lib/ then ensure the application loads them first via RPATH configuration.
Fixed with this workaround. Unfortunately, it requires bundling qt6.4.2, but it works flawlessly for now! Hope this works for you all too :3
Testing a fix locally, the issue is due to the binary being compiled against Qt 6.4.2, but our latest is 6.11, which introduces a new hardening feature into the library. This is an issue that's occurred with other packages such as PrismLauncher before. For now, we'll try to bundle, then contact the upstream devs. Hopefully this workaround works.
I cannot get this version to run, the qt5 version works correctly.
