This document summarizes an issue with Qt5 applications aborting when using the EGLFS platform on certain embedded devices. Running Qt5 applications would result in an error that the EGL display could not be initialized and the EGL surface could not be created. The fix is a patch from a GitHub repository that addresses this abort issue for the EGLFS platform in Qt5. Further steps are provided for setting up a cross-compilation toolchain and target filesystem for building Qt5 applications on these embedded platforms.
Qt5.0.0 eglfs abort issue
- 1. Qt5.0.x eglfs abort issue
- 2. Environment • Any EGLFS based plugin, that uses NULL window system (ie, single surface) – Example – Beagle-XM, 37x, Beaglebone, Sitara AM335x devices
- 3. Symptom Running any qt5 application will result in below error $$ ./analogclock –platform eglfs Could not initialize egl display EGL Error : Could not create the egl surface: error = 0x3003 Aborted
- 4. Call Stack • #3 0x425517f2 in QMessageLogger::fatal(char const*, ...) const () from <>/qt5_install/lib/libQt5Core.so.5 #4 0x43fa77a4 in QEglFSWindow::create() () from <>/qt5_install/plugins/platforms/libqeglfs.so
