Problem installing QT5 application using yocto on IMX8MINI

Hi everyone,

I'm posting on this forum because I'm stuck on a problem which not a lot of person has encoutered on the web apparently. I'm working on a IMX8MMINI and I want to deploy by using yocto, a qt application on it. The recipe is working, the apps is well installed in the yocto image, but I have a segmentation fault when I'm launching my app. This app is using QT5 with some packages like gstreamer and the error I have when using gdb is :

qt.qpa.xcb : xcb_shm_create_segment() failed for size 1228800
Segmentation fault

QOpenGLContext::shareGroup() const () from /usr/lib/libQt5Gui.so.5

Does anyone knows where could this come from ? Thanks

Hello kmarconi,

Looks like you are using X11 as backend, this is not supported by the MX8MMini.
