在Linux下打包Qt程序

 在windows和mac中qt有自己的依赖打包程序，分别是windeployqt和macdeployqt，但却没有自带的linuxdeployqt，需要下载三方程序使用。

下载linuxdeployqt：Releases · probonopd/linuxdeployqt · GitHubMakes Linux applications self-contained by copying in the libraries and plugins that the application uses, and optionally generates an AppImage. Can be used for Qt and other applications - Releases · probonopd/linuxdeployqthttps://github.com/probonopd/linuxdeployqt/releases

将最新版程序linuxdeployqt-x86_64.AppImage下载后改名为linuxdeployqt以方便调用。

将改名后的linuxdeployqt设置权限。

将修改好的文件放至系统环境目录/usr/local/bin下。

命令行内容如下：

$ chmod a+x linuxdeployqt-x86_64.AppImage
$ mv linuxdeployqt-x86_64.AppImage linuxdeployqt
$ mv linuxdeployqt /usr/local/bin 

调用linuxdeployqt –version测试程序是否安装成功

修改系统环境文件~/.bashrc增加自己的qt安装目录路径

export PATH=/home/chinaedu/Qt/5.15.2/gcc_64/bin:$PATH
export LIB_PATH=/home/chinaedu/Qt/5.15.2/gcc_64/lib:$LIB_PATH
export PLUGIN_PATH=/home/chinaedu/Qt/5.15.2/gcc_64/plugins:$PLUGIN_PATH
export QML2_PATH=/home/chinaedu/Qt/5.15.2/gcc_64/qml:$QML2_PATH

Qt的安装路径位置可以通过以下命令获取：whereis qt

使用qmake -v测试环境变理查看qmake版本是否正确。
