静态链接 MSVC 库，动态链接 Qt答案

【问题标题】：Statically link MSVC libraries, dynamically link Qt静态链接 MSVC 库，动态链接 Qt
【发布时间】：2020-01-13 09:59:08
【问题描述】：

我正在部署我用 Qt 构建的东西，由于 LGPL，它是动态链接的。我使用windeployqt.exe 收集必要的 dll，它在 Windows 10 机器上运行良好。当我在 Windows 7 机器上尝试时，我收到了这个错误：

程序无法启动，因为您的计算机中缺少 MSVCP140.dll。

经过一番研究，发现MSVCP140.dll 是Visual Studio 安装的System 32 中的一个dll。我应该让我的客户安装 Visual Studio，这在我的情况下不是一个选项，或者静态链接它。我尝试使用/MT，但我得到了：

用 /MD 覆盖 /MT

大概是因为我不能在不静态编译 Qt 本身的情况下静态链接 Qt 库。由于 LGPL，我想要做的是动态链接 Qt 库，并静态链接 MSVC 库。有没有办法做到这一点？最好来自 Qt 创建者。
我认为在程序中包含MSVCP140.dll 不是一种选择。

我正在使用 Visual Studio 2019 和 Qt 13.1

【问题讨论】：

如果您使用 VS2015 或更高版本构建 Windows 程序，则必须在任何目标系统上安装 MSVCP140.dll（名称将根据您的构建配置而有所不同） - 除非您专门使用早期的工具集。
@Adrian 如何在目标系统上安装MSVCP140.dll？有没有办法将它包含在构建中或静态链接它（也没有静态链接 Qt 库）？我正在使用 Visual Studio 2019
您必须重新编译 Qt 才能使用静态运行时（这与静态链接不同）。我不确定这是可能的。我的建议是将 vc_redist 与您为应用程序创建的安装程序打包在一起。我在工作中的所有应用程序中都使用 NSIS。然而，这主要是通过使用 CMake 和我十年前编写的一些 CMake 脚本为我完成的。 NSIS 不需要 CMake，因此您可以自己执行此操作。还有 WIX 和其他一些选项，例如 Qt 安装程序框架。

【解决方案1】：

为了让目标机器运行使用 Visual Studio 2015 或更高版本构建的软件，您需要在其上安装最新的 MSVC 运行时可再发行包。某些系统（例如 Windows 10）已经有足够新的版本。

您可以从此处获取最新包：vc_redist.XXX.exe，具体取决于目标平台。

选择“静态链接”选项仅适用于 MFC 库。

在 Stack Overflow 上有一个旧的 - 但可能很有帮助 - 问答 here。

【讨论】：

那么，解决方案是让.msi 安装程序在目标机器上安装它？
方法有很多！构建一个 MSI 是其中之一，但它不是微不足道的：您必须在目标目录中包含相关的 vc_redist.x64.exe（或其他），然后将代码添加到安装程序以运行该文件。其他软件包，如WiX，可能会更容易。或者你可以告诉你的最终用户他们应该从给定的链接中运行相关的 redist。

【解决方案2】：

正如drescherjm所说，最简单的方法是使用NSIS...... 一个简单的脚本可以创建一个包含所有必要文件的包...

我创建环境变量 MSVC_FOLDER、QT_MAJOR_VERSION 等，以使该脚本与 3 个版本的 Qt（5.5.1、5.8 和 5.11）和 3 个版本的 Visual Studio（2010、2013 和 2015）一起工作...

你可以简化这一切...

如果您能解释一下这个脚本的作用，那就太好了。
好吧，这个脚本打包了所有必要的文件以与您的应用程序一起分发......它将所有需要的 Qt DLL 和 Win Redist 压缩成一个“安装程序”.exe 文件。我配置了一些环境变量（MSVC_FOLDER、MSVC_RUNTIME、QT_MAJOR_VERSION、QT_MINOR_VERSION、QT_REVISION 和 QT_COMPILER。）以使该脚本适用于我们在公司中使用的所有环境/Qt 版本（5.5.1、5.8.0 和 5.11）和编译器（Visual Studio 2010、2013 和 2015）。
