Yes I have the opengl libraries installed on target PC.

I also tested a simple opengl program from the following link.

Hi,

i have the same problem. My application don't use QML, it use qtWebEngineWidget.

All library are present on target PC
ldd on app_file is OK (on target PC)

glxinfo is OK
glxgear display the gear on display


the output when my app start is :

QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
Could not find QtWebEngineProcess
Abandon


Have you resolved this problem (QXcbIntegration) ?
For my second problem (Could not find QtWebEngineProcess), i have no idea too...


Thanks

Nico

This is an old issue, but just in case: it looks like you might need to deploy the xcbglintegrations plugins (i.e. libqxcb-egl-integration.so and libqxcb-glx-integration.so). See here for more information.
