未解析的外部符号（LNK2001）
[英]Unresolved external symbol (LNK2001)
问题描述
I have two projects: Project A and project B. 
我有两个项目：项目A和项目B。
Project B references Project A. 项目B引用项目A。
When I compile I get the following errors: 编译时出现以下错误：
LINK : warning LNK4044: unrecognized option '/MaxILKSize:2146435072'; ignored
1>Testing.obj : error LNK2001: unresolved external symbol _IID_ITestIntOne
1>Testing.obj : error LNK2001: unresolved external symbol _IID_ITestIntTwo
1>Testing.obj : error LNK2001: unresolved external symbol _CLSID_WTest
1> Wait PDB close: Total time = 0.000s
1> Final: Total time = 1.547s
========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========
However project B is not using the SecurityCenterIntegration class at all, so I'm not sure why there are problems while linking to it. 但是，项目B根本没有使用SecurityCenterIntegration类，因此我不确定为什么链接到它时会出现问题。

You are missing Project A's libs or sources. 您缺少Project A的库或源。 Make sure you included all dependencies in the project settings. 确保在项目设置中包括所有依赖项。 Go to Properties > Linker > General and check Additional Library Directories are correct. 转到“属性”>“链接器”>“常规”，然后检查“其他库目录”是否正确。 Also add any additional libs and objs into Properties > Linker > Input > Additional Dependencies. 还将所有其他库和obj添加到“属性”>“链接器”>“输入”>“其他依赖项”。
