Visual Studio 2010中未解析的外部符号 [英] Unresolved external symbols in Visual Studio 2010

问题描述

我来自Xcode，试图在Visual Studio 2010中编译一个项目，我得到以下错误：

I am coming from Xcode, trying to compile a project in Visual Studio 2010, and I get the following errors:

2>ofxCLeye.obj : error LNK2019: unresolved external symbol "struct _GUID __cdecl CLEyeGetCameraUUID(int)" (?CLEyeGetCameraUUID@@YA?AU_GUID@@H@Z) referenced in function "public: static int __cdecl ofxCLeye::listDevices(void)" (?listDevices@ofxCLeye@@SAHXZ)

... etc etc...
2>bin\clEye_debug.exe : fatal error LNK1120: 10 unresolved externals

我想象编译器尝试链接 CLEyeMulticam.lib 但没有找到它。

你能指出我需要在VS2010中包含一个库吗？

Could you point me with the needed steps to include a library in VS2010 ?

谢谢你，

推荐答案

这是过分迂腐。如果这是一个预构建的库（不是构建为项目/解决方案的一部分），那么请确保

Apologies if this is overly pedantic. If this is a pre-built library (not built as part of the project/solution) then make sure you

a) #include the correct header
b) #define any requisite macros
c) speciy additional .lib dependencies as shown below. 

您需要指定一个完全限定的路径（d：\src\project\libs\camera.lib ），除非库文件在LIB环境变量中。

You will need to specify a fully qualifed path (d:\src\project\libs\camera.lib) unless the libary file is in the LIB environment variable.
