错误 LNK2001：无法解析的外部符号
我正在将我的项目从 vc6 转换为 VS 2010。当我编译我的项目时，对于可能的 .lib 输入，我会收到如下错误。我已将所有这些库添加到链接器->输入->附加依赖项，还在链接->常规->附加库目录中提供了这些.lib文件的路径。任何关于这方面的提示都会非常有帮助。
lb0.lib(ob0.obj) :error LNK2001: unresolved external symbol "void __stdcall SetLastExP(class ExceptionClass *)" (?SetLastExP@@YGXPAVExceptionClass@@@Z)
lb1.lib(ob1.obj) : error LNK2001: unresolved external symbol "void __stdcall SetLastExP(class ExceptionClass *)" (?SetLastExP@@YGXPAVExceptionClass@@@Z)

谢谢
I am converting my project from vc6 to VS 2010.When I compile my project i get error as below for may .lib inputs. I have added all these lib in the Linker-> Input-> Additional Dependencies, also provided the path of these .lib files in Link->General->Additional Library directories. Any tip on this will be very helpful.

您需要确定
SetLastExP()函数的定义位置。获取 .obj 文件并使用 dumpbin 检查它是否在您期望的装饰中实现。
将您看到的装饰与链接器错误消息中的装饰进行比较。
该函数可能被定义为
extern "C"而您的头文件没有反映这一点。You need to identify where the
SetLastExP()function is defined.Get the .obj file and check with dumpbin if it implements in the decoration that you expect.
Compare the decoration you see with the decoration you have in the Linker error message.
Probably the function is defined as
extern "C"while your header file doesn't reflect this.有时，如果您的子项目中有不同的字符集（
配置属性->常规），Visual Studio 会显示此类错误：Sometimes, if you have different Character sets (
Configuration properties->general) in your subprojects, Visual Studio shows this kind of error:
