Qt+vue开发桌面应用程序（三）程序打包

前面两章介绍了Qt+vue开发桌面应用程序（一）Qt部分介绍和Qt+vue开发桌面应用程序（二）Vue部分介绍，本文介绍程序打包发布

一、原理介绍

• Qt程序打包是通过windeployqt来实现，打包的windeployqt要与编译器一致。如：选择MSVC2019 64bit编译时，要选择Qt5.15\5.15.0\msvc2019_64\bin\目录下的windeployqt来打包
• 打包命令：windeployqt

二、打包程序

1. 配置程序图标
   在工程文件pro中添加RC_ICONS = favicon.ico，如图
   
   把图标文件favicon.ico放到和pro文件同一级目录，如图
   
   选择release编译就能生成带图标的exe程序，如图
   
2. 创建打包脚本release.bat，release.bat内容如下

start cmd /k "cd /d .\out\release && D:\Qt5.15\5.15.0\msvc2019_64\bin\windeployqt.exe Qt5_15Webenginewidgets.exe && del *.obj && del *.cpp && del *.h"

脚本说明：

• cd /d .\out\release：进入脚本目录下的out\release目录
• windeployqt.exe Qt5_15Webenginewidgets.exe：是打包命令
• del *.obj && del *.cpp && del *.h"：删除编译生成的中间文件

三、windeployqt说明

The simplest way to use windeployqt is to add the bin directory of your Qt
installation (e.g. <QT_DIR\bin>) to the PATH variable and then run:
  windeployqt <path-to-app-binary>
If ICU, ANGLE, etc. are not in the bin directory, they need to be in the PATH
variable. If your application uses Qt Quick, run:
  windeployqt --qmldir <path-to-app-qml-files> <path-to-app-binary>

Options:
  -?, -h, --help            Displays this help.
  -v, --version             Displays version information.
  --dir <directory>         Use directory instead of binary directory.
  --libdir <path>           Copy libraries to path.
  --plugindir <path>        Copy plugins to path.
  --debug                   Assume debug binaries.
  --release                 Assume release binaries.
  --pdb                     Deploy .pdb files (MSVC).
  --force                   Force updating files.
  --dry-run                 Simulation mode. Behave normally, but do not
                            copy/update any files.
  --no-patchqt              Do not patch the Qt5Core library.
  --no-plugins              Skip plugin deployment.
  --no-libraries            Skip library deployment.
  --qmldir <directory>      Scan for QML-imports starting from directory.
  --no-quick-import         Skip deployment of Qt Quick imports.
  --no-translations         Skip deployment of translations.
  --no-system-d3d-compiler  Skip deployment of the system D3D compiler.
  --compiler-runtime        Deploy compiler runtime (Desktop only).
  --no-compiler-runtime     Do not deploy compiler runtime (Desktop only).
  --webkit2                 Deployment of WebKit2 (web process).
  --no-webkit2              Skip deployment of WebKit2.
  --json                    Print to stdout in JSON format.
  --angle                   Force deployment of ANGLE.
  --no-angle                Disable deployment of ANGLE.
  --no-opengl-sw            Do not deploy the software rasterizer library.
  --list <option>           Print only the names of the files copied.
                            Available options:
                             source:   absolute path of the source files
                             target:   absolute path of the target files
                             relative: paths of the target files, relative
                                       to the target directory
                             mapping:  outputs the source and the relative
                                       target, suitable for use within an
                                       Appx mapping file
  --verbose <level>         Verbose level (0-2).

Qt libraries can be added by passing their name (-xml) or removed by passing
the name prepended by --no- (--no-xml). Available libraries:
bluetooth concurrent core declarative designer designercomponents enginio

Arguments:
  [files]                   Binaries or directory containing the binary.
