当有.dll文件和头文件时，如何创建一个.lib文件 [英] How to make a .lib file when have a .dll file and a header file

问题描述

我试图在visual studio中创建一个可以访问已经存在的.dll文件的应用程序。我需要应用程序调用例程。我也有一个头文件已经存在。

I am trying to create an application in visual studio that will be able to access a .dll file that already exists. I need the application to call up routines. I also have a header file that already exists.

我一直在互联网研究，发现我需要创建一个.lib文件。看这里的类似问题我发现了一个链接： http://support.microsoft.com/kb/131313
我不能遵循这些指示。

I have been researching on the internet and have found that I need to create a .lib file. Looking at similar questions on here I found a link: http://support.microsoft.com/kb/131313 I cannot however follow the directions.

链接中的信息说要创建一个DEF文件（我在其他地方阅读，需要将其编译为DLL，同名，但不知道该名称是什么，与.dll文件相同的名称？）。但是我不明白第一个方向，使用DUMPBIN / EXPORTS。然后我需要存根功能，然后与.obj文件有关（我不知道这些文件是什么）。

The information in the link says to make a DEF file ( I read elsewhere that this needs to be compiled as a DLL with the same name, but not sure what that name is, the same name as the .dll file?). But I do not understand the first direction, to 'Use DUMPBIN /EXPORTS'. I then need to 'stub out' functions, and then something to do with .OBJ files (I do not know what these files are).

推荐答案

您将需要 Microsoft Visual C ++ 2010 Express （或任何其他MSVC命令行工具源）和您的DLL。

You're going to need Microsoft Visual C++ 2010 Express (or any other source of MSVC command line tools), and your DLL.

步骤：

1. dumpbin / EXPORTS yourfile。 dll> yourfile.exports


2. 将所需功能的名称从 yourfile.exports 粘贴到新的code> yourfile.def 文件。在这个文件顶部添加一个单词 EXPORTS 的行。


3. 从 VC运行以下命令\bin 目录（其中 lib.exe 和其他编译工具所在的目录）。

1. dumpbin /EXPORTS yourfile.dll > yourfile.exports
2. Paste the names of the needed functions from yourfile.exports into a new yourfile.def file. Add a line with the word EXPORTS at the top of this file.
3. Run the following commands from VC\bin directory (the one where lib.exe and other compile tools reside).

 vcvars32.bat

 lib /def:yourfile.def /out:yourfile.lib

你应该得到两个生成的文件： yourfile.lib 和 yourfile.exp

You should get two files generated: yourfile.lib and yourfile.exp
