0.1 准备

(1) 安装交叉编译链，我使用的为：arm-linux-gnueabihf-gcc

(2) 交叉编译tslib,我使用的为厂家编译好的tslib,如果使用电阻式触摸屏必须使用tslib。

(3) 下载Qt5.7源码包

http://download.qt.io/official_releases/qt/5.7/5.7.0/submodules/qt-everywhere-opensource-src-5.7.0.tar.gz

1.1 安装Qtcreator

(1) 下载地址

http://mirrors.ustc.edu.cn/qtproject/archive/qt/5.8/5.8.0/qt-opensource-linux-x64-5.8.0.run

(2) 以root身份运行安装程序，并安装到合适的目录(/opt或/usr/local)

1.2 解压

tar -zxvf /home/chy/qianRuShi/ziliao/qt/qt-everywhere-opensource-src-5.7.0.tar.gz -C /opt/Qt5.8.0/5.8/

1.3 拷贝编译器配置文件

cp ./qtbase/mkspecs/linux-arm-gnueabi-g++ ./qtbase/mkspecs/linux-arm-gnueabihf-g++ -r

1.4 修改qmake.conf

vim ./qtbase/mkspecs/linux-arm-gnueabihf-g++/qmake.conf

内容如下：

1.5 配置并生成Makefile

./configure -prefix /opt/Qt5.8.0/5.8/Qt5.7_arm_linuxfs/ -opensource -shared -xplatform linux-arm-gnueabihf-g++ -qt-zlib -tslib -no-opengl -nomake examples -skip qtcanvas3d -I/opt/tslib/include -L/opt/tslib/lib -skip qt3d -qreal float -qt-libpng -qt-libjpeg -make libs -skip qtdeclarative

2.2 拷贝tslib库到开发板(可以通过vsftp传到开发板或制作根文件系统)

(1) 打包后通过vsftp传到开发板。

(2) 解压

tar -zxvf ./tslib.tar.zip

(3) 复制tslib/etc/ts.conf到开发板的/etc

cp ./tslib/etc/ts.conf /etc

(4) 复制tslib/bin/下的所有文件到开发板的/usr/bin/

cp ./tslib/bin/* /usr/bin/

(5) 复制tslib/lib/下的所有文件到开发板的/usr/lib/

cp -r ./tslib/lib/* /usr/lib/

(6) 配置环境变量,打开/etc/profile文件，并添加如下内容：

export TSLIB_PLUGINDIR=/usr/lib/ts/

export TSLIB_TSDEVICE=/dev/input/event0

export TSLIB_CALIBFILE=/etc/pointercal

export TSLIB_CONFFILE=/etc/ts.conf

export LD_LIBRARY_PATH=/usr/lib

2.3 拷贝Qt5.7的库到开发板(可以通过vsftp传到开发板或制作根文件系统)

(1) 打包后通过vsftp上传到开发板

(2) 解压

tar -zxvf ./lib.tar.zip

可能遇到的问题

出现如下问题时安装libiconv

QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed

QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed

(1) 下载链接：

https://ftp.gnu.org/gnu/libiconv/

echo "CC=arm-linux-gnueabihf-gcc"

./configure --prefix=/home/chy/out  --host=arm-linux-gnueabihf

make

make install

(3) 复制preloadable_libiconv.so到开发板的/lib目录，并配置在/etc/profile添加export LD_PRELOAD=/lib/preloadable_libiconv.so

出现如下问题时添加-skip qtdeclarative参数

ProjectERROR: Unknownmodule(s)inQT:quick
