[Qt-interest] unable to autodetect directFB for QT...

Tue Nov 16 05:03:47 CET 2010

hello,ya iam able to run those opengl examples given in <QT>/examples/opengl/hellogl... but they are running only on x11 window...:( i mean..  the QT which is built now is not able to detect the directfb... so iam getting the output only on X11 window...
here is the snapshot of the doutput iam getting... the example in neither running on DFB-X11 window, nor giving the display...its asking for some glx...
so i request you to plz look at the output and let me know.. what actually its asking me to do...

Hi Suma,
Sorry I'm bit busy today to look further.
Can you not run of the OpenGL examples to test it?

hey,,,QT is built without any errors... but when i try to execute any of the examples... they all are executing in X11 window instead of executing on DirectFB-X11 window...

while configuring also, it dint show me any msg of auto detecting and enabling of DirectfB..can you plz let me know...whether i have  missed any configuration parameter that enables auto detecting of DirectFB....

how should i test whether OpenGl is enabled on QT now?...plz help me...

Hey,
please dont' forget reply to list.

CAn you give us output of errror?
Maybe you should try compile the tests manually for Open GL and get it working. It's probably just it doesn't know where to locate your opengl
 headers/libs.

good morning..thanks for ur rply....
even if i remove -embedded x86 its still trying to detect opengles..

can you just let me know...
what actually are the configuration options that you want me to pass to just enable OpenGL for QT-4.7..

plz...
when i tried with this configuration option... it did detect Desktop OpenGL.. but during build it raised an error in OpenGL module of src
--------------------------------------------------------------------------------------------

 ./configure -v
 --prefix=/usr/Trolltech/QtEmbedded-4.6-directfb -no-webkit -opengl -plugin-gfx-directfb -qt-gfx-directfb -no-gfx-linuxfb

Hmm, you have -embedded x86 in the configure option?
