Does anybody know how to use am335x graphics acceleration in the QT?
I installed The Graphics_SDK_setuplinux_4_05_00_03.bin, and builded QT 4.7.3 with it, but the opengl examples of QT couldn't be run normally (there is no opengl graphics).
Here are some configurations and debugging informations, I hope someone can help me, Thank you very much!
1. Install Graphics SDK
./Graphics_SDK_setuplinux_4_05_00_03.bin --es8.x --sdk --mode console --prefix $HOME/Graphics_SDK_4_05_00_03
cd $HOME/Graphics_SDK_4_05_00_03
export ARCH=arm
make BUILD=debug OMAPES=8.x SUPPORT_XORG=0 all
make BUILD=debug OMAPES=8.x install
2. test gfxsdkdemos
/etc/init.d/335x-demo
cd /opt/gfxsdkdemos/ogles
The gfxsdkdemo program could be run normally.
3. Compile QT 4.7.3 Reference: http://processors.wiki.ti.com/index.php/Building_Qt_with_OpenGL_ES_accelerated_by_SGX
./configure -prefix /opt/qte-4.7.3 -debug -embedded arm -platform qws/linux-x86-g++ -xplatform qws/linux-armv7-sgx-g++ -depths 16,24,32 -no-mmx -no-3dnow -no-sse -no-sse2 -no-glib -no-cups -no-largefile -no-accessibility -no-openssl -no-gtkstyle -no-webkit -qt-mouse-pc -qt-mouse-linuxtp -qt-mouse-linuxinput -plugin-mouse-linuxtp -plugin-mouse-pc -fast -opengl es1 -qt-gfx-transformed -qt-gfx-vnc -qt-gfx-linuxfb -qt-gfx-multiscreen -qt-mouse-tslib -plugin-gfx-powervr -DQT_NO_QWS_CURSOR -QT_QWS_CLIENTBLIT -opensource -confirm-license
4. test qt opengl example [error occured ]
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:/opt/qte-4.7.3/lib
vi /etc/powervr.ini
modify "WindowSystem=libpvrPVR2D_FRONTWSEGL.so" to "WindowSystem=libpvrQWSWSEGL.so"
cd /opt/qte-4.7.3/examples/opengl/textures
./textures -qws -display powervr
An error occured in the kernel module：

5. When I change "WindowSystem=libpvrPVR2D_FRONTWSEGL.so" to "WindowSystem=libpvrQWSWSEGL.so",
The gfxsdkdemos couldn't be run. and the the kernel module error occured ：
PVR_K:(Error): PVRSRVCreateDCSwapChainKM: Too few buffers [975,
root/Graphics_SDK_4_05_00_03/GFX_Linux_KM/services4/srvkm/common/deviceclass.c]
6. The same problem exists when building qt 4.7.4 or with "-opengl es2"
