Linux/Wayland,
On ArchLinux, Qt is configured with the relocatable feature.
In QlibraryInfo.cpp, if the cdUp function call fails and prefixPath is not root, the program will not be able to exit the loop.
#if defined(Q_OS_LINUX) && !defined(QT_STATIC) && defined(__GLIBC__) const QString libdir = QString::fromLocal8Bit( qt_configure_strs.viewAt(QLibraryInfo::LibrariesPath - 1)); QDir prefixDir(prefixPath); while (!prefixDir.exists(libdir)) { prefixDir.cdUp(); // failed, prefixDir will not be changed prefixPath = prefixDir.absolutePath(); if (prefixDir.isRoot()) { // dead loop prefixPath.clear(); break; } } #endif
My suggestion for this case is to determine if the cdUp call was successful:
while (!prefixDir.exists(libdir)) { if(prefixDir.cdUp()){ // Avoiding a dead loop prefixPath.clear(); break; } prefixPath = prefixDir.absolutePath(); if (prefixDir.isRoot()) { prefixPath.clear(); break; } }
