I just installed the pentobi package in Ubuntu 19.04 beta and it fails to start up with the error message
QQmlApplicationEngine failed to load component
qrc:/qml/Main.qml:-1 File was compiled ahead of time with an incompatible
version of Qt and the original file cannot be found. Please recompile
I'm not sure if this is a temporary problem or if something needs to be fixed in the packaging. Pentobi 16.2 uses the QtQuickCompiler, which requires that the QML files are precompiled with the exact same version of Qt as is used at runtime, so pentobi needs to be recompiled whenever the Qt libraries are changed.
If using the QtQuickCompiler is inconvenient for packaging, it can be disabled by replacing "qtquick_compiler_add_resources" by "qt5_add_resources" in src/pentobi/CMakeLists.txt |
[Impact]
The application fails to start up.
This is because the executable contains precompiled QML code that will only work with a certain version of Qt. As a package maintainer, I was unaware of the dependency and did not know a rebuild after any Qt update would be necessary.
The fix is to disable QML precompilation.
[Test Case]
1. Open a console window.
2. Start the application by giving the command `pentobi`.
3. The game window should open.
[Regression Potential]
The patch changes how QML files are embedded in the executable: precompiled code to source form. If something were wrong with e.g. qrc paths (Qt Resource Compiler) in the patch, the game window would still not be displayed. However, that is not any worse that the current state of the package.
