qt-5.5.1移植

1.解压源码
$tar zxvf qt-everywhere-opensource-src-5.5.1.tar.gz
$cd qt-everywhere-opensource-src-5.5.1
2.修改配置文件
修改编译器为对应的交叉编译器：vi qtdbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf
去掉3D功能：vi qt.pro
#addModule(qt3d, qtdeclarative qtimageformats)
#addModule(qtcanvas3d, qtdeclarative)
3.配置及编译
$./configure -prefix /opt/qt-5.5.1 -opensource -release -xplatform linux-arm-gnueabi-g++ \
-no-c++11 -no-opengl -no-xcb -no-dbus -strip -silent -linuxfb -tslib \
-I/opt/tslib-1.4/include -L/opt/tslib-1.4/lib
$make -j2
$sudo make install

4.部署
将编译出来的/opt/qt-5.5.1整个目录拷贝到开发板.
并配置好环境变量,请参考：qt-5.5.1运行环境配置.

5.运行测试程序
$ . /opt/qtenv.sh
$/opt/qt-5.5.1/examples/widgets/widgets/calculator/calculator

注意：静态编译目前移植到开发版上有问题，提示找不到插件linuxfb.
