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.

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

Qt Code: 
  1. #!/bin/sh
  2. export LD_LIBRARY_PATH=`pwd`:${LD_LIBRARY_PATH}
  3. export QML_IMPORT_PATH=`pwd`/imports:`pwd`/qml
  4. export QML2_IMPORT_PATH=`pwd`/qml/
  5. export QT_QPA_PLATFORM_PLUGIN_PATH=`pwd`/plugins/platforms
  6. ./myapp

I got the following errors.

Qt Code: 
  1. QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
  2. Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior 2, swapInterval 1, profile  0) 
  3. Aborted (core dumped)

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

Thanks,
Vinoth
