如何静态链接.DLL？

[英]How to link a .DLL statically?

原文 2009-01-08 12:03:21 5 4 c++/ dll/ linker/ static-linking

We have a (pure native C++) .DLL that is build by VS. 我们有一个由VS构建的（纯本机C ++）.DLL。 As clients we have some native C++ applications and a .Net-Wrapper around this DLL written in C++/CLI. 作为客户端，我们有一些本机C ++应用程序和围绕这个用C ++ / CLI编写的DLL的.Net-Wrapper。 Finally there are some client applications for the .Net-Wrapper written in C#. 最后，有一些用C＃编写的.Net-Wrapper客户端应用程序。

My problem is that the native.dll must be distributed in a different way than the .Net world works and the VS does not keeps track of that DLL. 我的问题是native.dll必须以与.Net世界不同的方式分发，并且VS不会跟踪该DLL。 So to let all my C# Apps work correctly I have to copy it to each executable directory or put it somwhere in %PATH% (which I would avoid on developer computers since they may want to start different apps with different versions of the DLL). 因此，要让我的所有C＃应用程序正常工作，我必须将其复制到每个可执行文件目录中，或者将其放在％PATH％中（我会避免在开发人员计算机上，因为他们可能希望使用不同版本的DLL启动不同的应用程序）。 Even bigger problems occur if there are UserControls that reference the Wrapper-DLL: You have to copy the DLL to VS's directory or again to %PATH%. 如果存在引用Wrapper-DLL的UserControl，则会出现更大的问题：您必须将DLL复制到VS的目录或再次复制到％PATH％。 But the worst case occurs with our Translator tool. 但最坏的情况发生在我们的翻译工具上。 This tool keeps track of .Net-Assemblies and packs them into Translator-packages that can be send to an external translator. 该工具跟踪.Net-Assemblies并将它们打包到可以发送给外部翻译器的Translator-packages中。 As far as I know there is no way to put the native .DLL into that package! 据我所知，没有办法将原生.DLL放入该包中！

So I plan to link the native DLL statically into the .Net-Wrapper which would solve my problems. 所以我打算将原生DLL静态链接到.Net-Wrapper，这将解决我的问题。 But for our Native applications this native DLL must still be a DLL. 但对于我们的Native应用程序，此本机DLL仍必须是DLL。

So I have two options: 所以我有两个选择：

Make two projects of that (one that generates a static library; and one that creates a dynamic one => I try to avoid this) 制作两个项目（一个生成静态库;一个创建动态库=>我尽量避免这种情况）
Find a solution to link DLLs statically 找到一个静态链接DLL的解决方案
Find a way to let VS generate two outputs from one project 找到一种让VS从一个项目生成两个输出的方法

4 个解决方案

In the C++ project file for the dll, create two configurations, one that generates a DLL and one that generates a .lib. 在dll的C ++项目文件中，创建两个配置，一个生成DLL，另一个生成.lib。 Two projects are not necessary, since any .NET/C++ project can support multiple build configurations (this is how Release and Debug versions build differently). 两个项目不是必需的，因为任何.NET / C ++项目都可以支持多个构建配置（这就是Release和Debug版本以不同方式构建的方式）。

另一种选择是有两个项目，一个项目将输出一个可以静态链接的.lib，另一个项目将输出.dll并将你的.lib作为依赖项，你应该将.def添加到你的.dll中您计划导出的符号，否则它将为空。

拿起DLL的副本到Lib （编辑：如果你找不到更便宜的选项）

You can generate a dll and export the entry point to a lib using dllexport , this is explained here 您可以使用dllexport生成一个dll并将入口点导出到lib，这在此处进行了解释
