环境配置
- 打开命令行窗口，配置环境变量（临时的）
export PATH=/opt/arm-none-linux-gnueabihf-9.2/bin:$PATH
- 修改配置文件
/home/qsqya/compile/qt5.12.9/qt-everywhere-src-5.12.9/qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf
替换以下内容
:%s#arm-linux-gnueabi#arm-none-linux-gnueabihf#g
- 编写编译脚本
/home/qsqya/compile/qt5.12.9/compile.sh
#!/bin/sh
cd ./qt-everywhere-src-5.12.9
./configure -prefix /home/qsqya/compile/qt5.12.9/build \
-opensource \
-release \
-confirm-license \
-xplatform linux-arm-gnueabi-g++ \
-shared \
-nomake examples \
-nomake tests \
-no-opengl
路径自行修改
4. 执行脚本
./compile.sh
make -j 4 ##编译
make install ##安装
