qt5.4 with platform eglfs is Segmentation fault

[Y.L Chiu]

Hello, I have a question.

I use qt5.4 example on my imx6 board, then commad:

./usr/local/qt5/examples/widgets/richtext/textedit/textedit  -platform linuxfb -plugin tslib 

My board screen could show the "textedit".

But, if I command:

./usr/local/qt5/examples/widgets/richtext/textedit/textedit  -platform eglfs -plugin tslib 

The textedit application isn't work, and I got error:

Segmentation fault

I check /usr/local/qt5/plugins/platforms/, there are:

libqdirectfb.so  libqeglfs.so  libqlinuxfb.so  libqminimalegl.so  libqminimal.so  libqoffscreen.so

I command export QT_DEBUG_PLUGINS=1, then run textedit with platform eglfs, I got the message:

root@freescale /usr/local/qt5$ ./examples/widgets/richtext/textedit/textedit -platform egl
fs -plugin EvdevMouse
