1. 编译Qt4 for x11这样可以得到Qt Designer, Assistant 以及非常重要的qvfb开发工具。
export PATH=Qt源代码目录/bin:$PATH
./configure -prefix /opt/qt4x11(可以不指定安装位置) -opensource -L Qt源代码目录/lib
make install
cd Qt源代码目录/tools/qvfb
make install
2. 编译Qt4 embedded x86 for qvfb，得到输出往qvfb的embedded x86版本便于在x11下调试
export PATH=/Qt源代码目录/bin:$PATH
./configure -embedded x86 -qvfb -prefix /opt/qtqvfb -opensource -L /Qt源代码目录/lib
make install
3.编译Qt4 embedded for omap35xx (我的机器配置，懒得改了,要打开omap的neon处理器的可以查下资料)
export PATH=/root/qt-4.7.3/bin:/opt/CodeSourcery/Sourcery_G++_Lite/bin:$PATH
export LIBRARY_PATH=/opt/dvsdk/linux-devkit/arm-none-linux-gnueabi/usr/lib
export C_INCLUDE_PATH=/opt/dvsdk/linux-devkit/arm-none-linux-gnueabi/usr/include
export CPLUS_INCLUDE_PATH=/opt/dvsdk/linux-devkit/arm-none-linux-gnueabi/usr/include
./configure -embedded arm -xplatform qws/linux-arm-gnueabi-g++ -prefix /usr -opensource -L /root/qt-4.7.3/lib
make
