If you set and used a prefix for the cross-compiled version above (ie you did 
a make install to install the libs/headers/docs somewhere else) then just do a 
make confclean in your source directory and reconfigure with something along 
these lines:

./configure -prefix /usr/local/qt-embedded \
            -embedded \
            -qt-gfx-qvfb \
            -depths 8,16,18,32 \
            -qt-kbd-qvfb \
            -qt-mouse-qvfb

or with a different prefix plus whatever other options you wish to use. The 
configure script should identify your system architecture as x86 and use the 
correct toolchain. Then run make and make install as per normal.

To use this you then simply need to set up your path to find the correct 
version of qmake depending on if you are doing a host or target build.

To actually run a host build using Qt embedded it is useful to build the qvfb 
application. This can be found in your usual desktop build of Qt. Launch the 
qvfb application then launch your own app passing in the -qws option on the 
command line and it will display inside the qvfb application.

Hope this helps,
