从引用项目的.lib文件获取LNK1104错误 [英] getting LNK1104 error from a referenced project's .lib file

问题描述

我有一个解决方案有两个项目： myProject ，一个DLL和 myProject_Tester ，一个Win32控制台应用程序

I have a solution with two projects: myProject, a DLL, and myProject_Tester, a Win32 console application that I'm using to debug the DLL.

当我构建解决方案时，我在错误列表中收到此错误消息：

When I build the solution, I get this error message in the Error List:

error LNK1104:
cannot open file 'U:\Software Development\c++ projects\myProject\Debug\myProject.lib'
U:\Software Development\c++ projects\myProject\myProject_Tester\LINK    
myProject_Tester

$ b b

我添加了 myProject 作为 myProject_Tester 中的引用，但是当我编辑 myProject_Tester.cpp ，并尝试输入 #includemyProjectDLL.h（ myProject ）包含头文件， myProjectDLL.h 不会显示在Intellisense中。

I added myProject as a reference in myProject_Tester, but when I'm editing myProject_Tester.cpp, and I try to enter #include "myProjectDLL.h" (the header file for myProject) to include the header file, myProjectDLL.h doesn't show up in the Intellisense.

我还添加了 myProject_Tester 的附加包含目录下的 U：\Software Development\c ++ projects\myProject\Debug c $ c>。

I also added U:\Software Development\c++ projects\myProject\Debug under Additional Include Directories for myProject_Tester.

在 myProject_Tester 的属性中还有其他地方，它与 myProject ？

Is there somewhere else in the properties for myProject_Tester that I need to configure something to connect it with myProject?

编辑：这是我用于myProjectDLL.h的头文件：

Here is the header file I'm using for myProjectDLL.h:

//myProjectDLL.h

#ifdef MYPROJECT_EXPORTS
#define MYPROJECT_API __declspec(dllexport) 
#else
#define MYPROJECT_API __declspec(dllimport) 
#endif

namespace myProject
{
    class FileOperator
    {
    public:
        static int openDoc(int projectID,int docID);
    };
}

推荐答案

其他包含目录设置正确。您的.h文件肯定不存在于Debug文件夹中。

You didn't set the Additional Include Directories setting correctly. Your .h file surely isn't present in the Debug folder. Make it U:\Software Development\c++ projects\myProject instead.

在构建myProject项目之后，确保.lib文件实际存在，否则请改用U：\Software Development\c ++ projects\myProject。如果它缺少，那么你忘了使用__declspec（dllexport）来告诉链接器导出你想要提供的函数或类。

Do make sure the .lib file actually exists after building the "myProject" project. If it is missing then you forgot to use __declspec(dllexport) to tell the linker to export the functions or classes that you want to make available.

并确保项目正以正确的顺序构建，myProject必须在控制台项目开始构建之前构建。如果需要，在解决方案资源管理器窗口中右键单击控制台项目，单击项目依赖关系，然后在对话框中勾选myProject。

And make sure that the projects are getting build in the correct order, "myProject" must be built before the console project starts building. If necessary, right-click the console project in the Solution Explorer window, click "Project Dependencies" and tick myProject in the dialog box.
