c++ - Visual Studio 2010 中未解析的外部符号

Question

我来自 Xcode，试图在 Visual Studio 2010 中编译一个项目，但出现以下错误:

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)
2>ofxCLeye.obj : error LNK2019: unresolved external symbol "int __cdecl CLEyeGetCameraCount(void)" (?CLEyeGetCameraCount@@YAHXZ) referenced in function "public: static int __cdecl ofxCLeye::listDevices(void)" (?listDevices@ofxCLeye@@SAHXZ)
2>ofxCLeye.obj : error LNK2019: unresolved external symbol "bool __cdecl CLEyeCameraGetFrameDimensions(void *,int &,int &)" (?CLEyeCameraGetFrameDimensions@@YA_NPAXAAH1@Z) referenced in function "public: void __thiscall ofxCLeye::grabFrame(void)" (?grabFrame@ofxCLeye@@QAEXXZ)
2>ofxCLeye.obj : error LNK2019: unresolved external symbol "bool __cdecl CLEyeCameraGetFrame(void *,unsigned char *,int)" (?CLEyeCameraGetFrame@@YA_NPAXPAEH@Z) referenced in function "public: void __thiscall ofxCLeye::grabFrame(void)" (?grabFrame@ofxCLeye@@QAEXXZ)
2>ofxCLeye.obj : error LNK2019: unresolved external symbol "bool __cdecl CLEyeDestroyCamera(void *)" (?CLEyeDestroyCamera@@YA_NPAX@Z) referenced in function "public: virtual void __thiscall ofxCLeye::close(void)" (?close@ofxCLeye@@UAEXXZ)
2>ofxCLeye.obj : error LNK2019: unresolved external symbol "bool __cdecl CLEyeCameraStop(void *)" (?CLEyeCameraStop@@YA_NPAX@Z) referenced in function "public: virtual void __thiscall ofxCLeye::close(void)" (?close@ofxCLeye@@UAEXXZ)
... etc etc...
2>bin\clEye_debug.exe : fatal error LNK1120: 10 unresolved externals

我想编译器正在尝试链接 CLEyeMulticam.lib 但没有找到它。我认为我已经正确配置了它。

你能指出在 VS2010 中包含库所需的步骤吗？

谢谢，

如果这过于迂腐，我们深表歉意。如果这是一个预构建的库(不是作为项目/解决方案的一部分构建的)，那么请确保您

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

除非库文件位于 LIB 环境变量中，否则您需要指定完全限定路径 (d:\src\project\libs\camera.lib)。
