1.配置5.4.0的交叉编译工具链
arm-linux-gnueabi-5.4.0.tar.xz
2.找到QT库 ,例如我的放在家目录
Qt-Embedded-5.7.0.tar.xz
3.解压到 linux 系统的 /usr/local目录中
sudo tar -xvf Qt-Embedded-5.7.0.tar.xz -C /usr/local/
特别注意:C字母一定要大写
4.利用QT 交叉编译工具链,编译QT 程序
1.进入到需要编译的QT 源码目录中
cd 源码目录
2.利用QMAKE 工具生成 Makefile 文件
/usr/local/Qt-Embedded-5.7.0/bin/qmake
看到Makefile即编译成功
3.编译即可
make
4.把源码目录名下载到开发板运行即可
scp xiangmu [email protected]:~
注意:如果make出现一下错误
该错误原因是之前已经按照这个工程成功运行了多次,在没有任何修改下,程序“懒得”再运行了。可以在CPP文件中的随意空白位置添加个空格,或者随意做一些无关紧要的改动即可再次运行
