Hi,
I am cross compiling qt-all-opensource-src-4.5.0 for arm board (Davinci) with following configure options.
./configure -qvfb
export CC=/opt/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-gcc
export CXX=/opt/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-g++
./configure -embedded arm -platform qws/linux-x86-g++ -xplatform qws/linux-arm-g++ -qvfb -little-endian -host-little-endian -webkit
gmake
while make i got following errors.

I have tried adding above undefined functions as dummy functions in qt-all-opensource-src-4.5.0/src/corelib/thread/qatomic.cpp file and recompile source but it gives same errors.
What could be the reson for these errors.
Thanks in advance.
