hi3531移植qt4.8.6，并裁剪

cd /opt/tools/qt-everywhere-opensource-src-4.8.6/
cd mkspecs/qws/
cp linux-arm-g++/ linux-armhi3531-g++
修改linux-armhi3531-g++中的qmake.conf， 改为如下

 # modifications to g++.confQMAKE_CC                = arm-hisiv200-linux-gccQMAKE_CXX               = arm-hisiv200-linux-g++QMAKE_LINK              = arm-hisiv200-linux-g++QMAKE_LINK_SHLIB        = arm-hisiv200-linux-g++ # modifications to linux.confQMAKE_AR                = arm-hisiv200-linux-ar cqsQMAKE_OBJCOPY           = arm-hisiv200-linux-objcopyQMAKE_STRIP             = arm-hisiv200-linux-strip

cd ../../
./configure –prefix=/usr/local/qt-4.8.6-hi3531 -opensource -confirm-license -qt-sql-sqlite -qt-gfx-linuxfb -plugin-sql-sqlit -no-qt3support -no-phonon -no-svg -no-webkit -no-javascript-jit -no-script -no-scripttools -no-declarative -no-declarative-debug -qt-zlib -no-gif -qt-libtiff -qt-libpng -no-libmng -qt-libjpeg -no-rpath -no-pch -no-3dnow -no-avx -no-neon -no-openssl -no-nis -no-cups -no-dbus -embedded arm -platform linux-g++ -xplatform qws/linux-armhi3531-g++ -little-endian -qt-freetype -no-opengl -no-glib -nomake docs

其中/usr/local/qt-4.8.6-hi3531 是qt安装目录
-xplatform qws/linux-armhi3531-g++ 表示交叉编译的平台，即上面创建的

make && make install

步骤2：
测试编译安装是否成功
/usr/local/qt-4.8.6-hi3531/bin/qmake -v
输出
QMake version 2.01a
Using Qt version 4.8.6 in /usr/local/qt-4.8.6-hi3531/lib

编译demo程序
cd /opt/kaifaban/hi3531/demo/demo/
/usr/local/qt-4.8.6-hi3531/bin/qmake //生成makefile
make //生成可执行程序demo
运行程序时，需要安装到 文件系统/usr/lib下的库和字体文件
cp wenquanyi_micro_hei_24_50.qpf2 /usr/lib/fonts
cp /usr/local/qt-4.8.6-hi3531/lib/libQtCore.so.4 /usr/lib/
cp /usr/local/qt-4.8.6-hi3531/lib/libQtGui.so.4 /usr/lib/
cp /usr/local/qt-4.8.6-hi3531/lib/libQtNetwork.so.4 /usr/lib/
如果不想考到文件系统，用于临时测试，可以先通过环境变量方式指定：
假定以上文件已放入/nand/usrtest/qt4lib目录
export LD_LIBRARY_PATH=/nand/usrtest/qt4lib/:$LD_LIBRARY_PATH
export QT_QWS_FONTDIR=/nand/usrtest/qt4lib/fonts/

运行程序前需要进行的准备
./sample_hifb
然后运行自己编写的测试程序，./demo –qws

如果出现提示字体找不到的错误，需要执行
export QT_QWS_FONTDIR=/nand/usrtest/qt4lib/fonts/

裁剪

qconfig-ttt_777.h 由qconfig生成
放在src\corelib\global目录下
