I see the latest version of qt embedded does not include the 
plugin-gfx-powervr. The latest qt4-embedded.inc is configured:

QT_CONFIG_FLAGS += " \
   -embedded ${QT_ARCH} \
   -qtlibinfix ${QT_LIBINFIX} \
   -plugin-gfx-transformed -plugin-gfx-qvfb -plugin-gfx-vnc
   -plugin-gfx-directfb \
   -plugin-mouse-tslib -qt-mouse-pc -qt-mouse-qvfb -qt-mouse-linuxinput \
   -qt-kbd-tty \
   -DQT_KEYPAD_NAVIGATION \
   "

but without -plugin-gfx-powervr. This is because powervr need  
-DQT_NO_QWS_CURSOR and  -DQT_WS_CLIENTBLIT?
I'm trying to modify the recipes to include powervr pluging, i have add 
-plugin-gfx-powervr -DQT_NO_QWS_CURSOR -DQT_WS_CLIENTBLIT. But this 
operation need two patches 
https://github.com/prabindh/qt-configs/tree/master/qt4.8

Somebody know a good solution to get the possibility to compile this 
plugin?
Thank's for your time.

Hi,

are you sure you need the plugin? Koen mostly stated that the powervr plugin doesnt give much improvement.

I'm using beagleboard... and i'm read i need powervr to improve 
performance of opengl. But i can't test if is true or not because i 
can't build the plugin :)

Ok, now i'm trying to build the plugin-gfx-powervr but i need a little 
help with editing the recipes.

For my test i'm editing the qt4.inc with this lines:

QT_GLFLAGS ?= "-opengl es2 -depths 16,24,32 -plugin-gfx-powervr"

and i add at the end of line of QT_CONFIG_FLAGS
  "-DQT_NO_QWS_CURSOR \
   -DQT_WS_CLIENTLIT"

so i start the building with:
MACHINE=beagleboard ./oebb.sh bitbake qt4-embedded

But the build blocks on this error:
pvrqwswegl.c:42:30: fatal error: GLES/eglplatform.h: No such file or 
directory

So i apply these patches from 
https://github.com/prabindh/qt-configs/tree/master/qt4.8 and build is 
finish correclty.
Problem #1 i see the rm_work delete the folder of qt library but i need 
that for cross-compile with qt-creator my program.
I see the new library is installed in 
/tmp.../sysroot/beagleboard/usr/lib so i copy and paste on my sdcard in 
the same position.
And i run qdemo -qws -display powervr and i get:

Problem #2
QLibraryPrivate::loadPlugin failed on 
"/usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so" : "Cannot load 
library /usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so: 
(/usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so: undefined symbol: 
_ZNK16QWSWindowSurface12directRegionEv)"
"Cannot load library 
/usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so: 
(/usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so: undefined symbol: 
_ZNK16QWSWindowSurface12directRegionEv)"  could not load

Anybody have some info to solve the problem?
Thank's

Hm looks like libqgfxpvregl.so needs more some so-libs depends, find out in which lib the Symbol is e.g. objdump or readelf and
tweak the linker line for libqgfxpvregl.
