一、安装海思编译链

安装海思编译链(如arm-hisiv300-linux-*)，不做赘述。

二、下载Qt4.8.6源码包

源码包：qt-everywhere-opensource-src-4.8.6.tar.gz

三、解压源码包

将源码包拷贝到Ubuntu的Desktop

进入Desktop：cd ~/Desktop

解压：tar -xzvf qt-everywhere-opensource-src-4.8.6.tar.gz

四、修改QT源码的io.pri文件

进入源码包目录：cd ~/Desktop/qt-everywhere-opensource-src-4.8.6

修改io.pri文件:~/Desktop/qt-everywhere-opensource-src-4.8.6/src/corelib/io/io.pri

添加arm-hisiv300-linux-*编译链

五、添加Hisi交叉编译链配置文件qmake.conf

进入源码包目录：cd ~/Desktop/qt-everywhere-opensource-src-4.8.6

创建arm-hisiv300-linux-的qmake.cof文件： cp mkspecs/qws/linux-arm-gnueabi-g++/   mkspecs/qws/arm-hisiv300-linux-g++/ -r

修改mkspecs/qws/arm-hisiv300-linux-g++/qmake.conf文件，如下：

#

# qmake configurationfor building with arm-none-linux-gnueabi-g++#

include(../../common/linux.conf)

include(../../common/gcc-base-unix.conf)

include(../../common/g++-unix.conf)

include(../../common/qws.conf)

# modifications to g++.conf

QMAKE_CC= /opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/arm-hisiv300-linux-gcc

QMAKE_CXX=/opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/arm-hisiv300-linux-g++QMAKE_LINK=/opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/arm-hisiv300-linux-g++QMAKE_LINK_SHLIB= /opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/arm-hisiv300-linux-g++# modifications to linux.conf

QMAKE_AR= /opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/arm-hisiv300-linux-ar cqs

QMAKE_OBJCOPY= /opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/arm-hisiv300-linux-objcopy

QMAKE_NM= /opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/arm-hisiv300-linux-nm -P

QMAKE_STRIP=/opt/hisi-linux/x86-arm/arm-hisiv300-linux/target/bin/arm-hisiv300-linux-strip

load(qt_config)

六、交叉编译前，配置4.8.6源码

./configure --prefix=/opt/qt4.8.6_transfrom -opensource -confirm-license -qt-sql-sqlite -qt-gfx-linuxfb -qt-gfx-transformed -plugin-sql-sqlite -no-qt3support -no-phonon -no-svg -no-webkit -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/arm-hisiv300-linux-g++ -little-endian -qt-freetype -no-opengl -no-glib -nomake demos -nomake examples -nomake docs -nomake tools

其中：

--prefix=/opt/qt4.8.6_transfrom 安装目录

-qt-gfx-transformed 支持旋转显示

-xplatform qws/arm-hisiv300-linux-g++ 指定qmake.conf配置

七、编译

make

八、安装

make install

九、移植

将/opt/qt4.8.6_transfrom/lib资源拷贝到/usr/local/Trolltech/Qt4.8.6/lib。

环境配置：

export QT_INSTALL_PATH=/usr/local/Trolltech/Qt4.8.6

export LD_LIBRARY_PATH=/lib:/usr/lib:${QT_INSTALL_PATH}/lib:${LD_LIBRARY_PATH}

export QT_QWS_FONTDIR=${QT_INSTALL_PATH}/lib/fonts

export QWS_DISPLAY="Transformed:Rot0:LinuxFB:/dev/fb1"

解析：

静态设置旋转参数：Transformed:Rot0,旋转角度为0。若要配置为90,180,270,可配置为Transformed:Rot90，Transformed:Rot180，Transformed:Rot270。

动态设置旋转参数：

export QWS_DISPLAY="Transformed:LinuxFB:/dev/fb1"

QWSDisplay::setTransformation(0,0);第一个参数0,1,2,3分别对应0,90,180,270度,第二个参数设置为0。

十、Ubuntu安装QtCreator

下载路径：http://download.qt.io/archive/qtcreator/

以QtCreator2.5.2为例，安装包：qt-creator-linux-x86_64-opensource-2.5.2.bin

双击安装即可

安装后，打开软件，如图1所示

图1.QtCreator开启界面

打开配置界面：Tools->Options->Build&Run，如图2所示

图2.Build&Run之Qt Version

点击Add键，选择所需添加的qmake(/opt/qt4.8.6_transfrom/bin/qmake)，如图2所示

添加交叉编译链(arm-hisiv300-linux-g++与arm-hisiv300-linux-gcc)，如图3所示
