This code is ok for me...
How do you compile it ?
I suppose that you did like this :
qmake -project
qmake
make
with the qmake of qtopia (for cross compile)
I tested this code on the board AT91SAM9261-EK (arm based) and on my desktop computer and it is working well (see the shot in attachment)
Maybe the Qtopia libs are not installed correctly... or try the latest release of qtopia core. I run qtopia-core-opensource-src-4.3.4 on my board.
Cheers,
Guillaume

hi !
I do not really use buildroot... I just use the cross-compile tools... because buildroot have always problems... ;p
To begin add the buildroot cross compile tools to the PATH :
export PATH=$PATH:/<path_to_buildroot>/build_arm/staging_dir/bin/
(do it in each konsole/Terminal or add it to your ~/.profile or ~/.bashrc)
Then you have to download the source package, untar it, etc...
Do that :
wget ftp://ftp.trolltech.com/qt/source/qtopia-core-opensource-src-4.3.4.tar.gz
gunzip qtopia-core-opensource-src-4.3.4.tar.gz
tar xvvf qtopia-core-opensource-src-4.3.4.tar
mkdir build_dir_qtopia_4.3.4
cd build_dir_qtopia_4.3.4
../qtopia-core-opensource-src-4.3.4/configure -prefix <install_path> -no-sxe -embedded arm -xplatform qws/linux-arm-g++
make su -c 'make install'
If you want to have the support of the touchscreen through tslib, add the following options to the configure :
-qt-mouse-tslib -L <path_to_lib_of_tslib> -I <path_to_include_of_tslib>
it should be ok !
Cheers,
Guillaume

Objet : Re: RE : No output on framebuffer
I have been trying to build Qtopia under Buildroot, (buildroot.uclibc.org)
but that always fails.
It looks like the buildprocess mixes up host tools and native tools.
Anyone has scripts/instructions that succeeds building for AT91SAM9's
which they care to share with me?
