vc++打包发布自带依赖dll

问题

相信很多人都遇到过vx项目打包发布出去之后，用户安装运行提示缺少mfc140u.dll(数字是vc版本决定的)，然而奇怪的是很少有人讨论具体怎么解决这个问题

我尝试过的办法

1. 静态发布
   编译时候选择静态方式使用mfc，all done，打包之后的程序自带依赖

问题：
某些依赖组件只有dll，没有lib。别问我为什么，这里不做讨论。这时候就没办法使用静态方式的mfc了

2. 安装启动vc发型包安装
   innosetup打包安装程序时候，打包vc发型包，安装过程中进行安装。

[Files]
Source: "D:\dep\mfc140u.dll"; DestDir: "{app}"; Flags: ignoreversion

[Run]
;Filename: {tmp}\vc_redist.x86.exe; Parameters: "/q /passive /Q:a /c:""msiexec /q /i vcredist.msi"""; StatusMsg: "Installing VC++ 2017 Redistributables..."

问题：

• 装完要重启，不然找不到mfc140u.dll
• 安装包体积大

3. 查看dll依赖，innosetup制作安装包时候拷贝

查看依赖

> cd c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin>
> dumpbin /dependents xxx.exe

加如innosetup

完美解决，比第二种方式体积小了将近一半
