Deploying Qt 5 application on Linux

[vinothk57]

I have installed QT 5.5.1 on my Ubutu 14.04 64 bit machine using the online installer.

I have developed an application using QML using QtCreator. The application runs fine on the same PC.

I wanted to run the application on another Ubuntu PC without QT installation.

Using ldd I found the dynamically linked QT libraries for my application.

To copy to clipboard, switch view to plain text mode 

I copied all the dependent libraries to my target machine and also created a run script containing the following:

#!/bin/sh
export LD_LIBRARY_PATH=`pwd`:${LD_LIBRARY_PATH}
export QML_IMPORT_PATH=`pwd`/imports:`pwd`/qml
export QML2_IMPORT_PATH=`pwd`/qml/
export QT_QPA_PLATFORM_PLUGIN_PATH=`pwd`/plugins/platforms
./myapp

#!/bin/sh
export LD_LIBRARY_PATH=`pwd`:${LD_LIBRARY_PATH}
export QML_IMPORT_PATH=`pwd`/imports:`pwd`/qml
export QML2_IMPORT_PATH=`pwd`/qml/
export QT_QPA_PLATFORM_PLUGIN_PATH=`pwd`/plugins/platforms
./myapp

To copy to clipboard, switch view to plain text mode 

I got the following errors.

QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled

Can somebody help, what could be the issue here? Am I missing anything?

Is that ldd output from the developer PC or the target?

If it is not for the target, how does it look there?
Are the OpenGL libraries installed?

Cheers,

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.
