如何修复已定义的类模板？
我正在将 ZipArchive 库实现到我的项目中，我与它斗争了一个多小时，使其正确设置以阻止所有链接器错误。但现在我仍然剩下这个问题，我不确定修复它的最佳方法，需要一些帮助。
C:\Program Files\Microsoft Visual Studio 9.0\VC\atlmfc\include\afxtls_.h(199) : error C2953: 'CThreadLocal' : class template has already been defined
c:\dev-mms\hl2sdk-ob-valve\public\tier0/threadtools.h(283) : see declaration of 'CThreadLocal'
C:\Program Files\Microsoft Visual Studio 9.0\VC\atlmfc\include\afxtls_.h(202) : warning C4005: 'THREAD_LOCAL' : macro redefinition
c:\dev-mms\hl2sdk-ob-valve\public\tier0/threadtools.h(71) : see previous definition of 'THREAD_LOCAL'
I am implementing ZipArchive library into my project, and I fought with it for over an hour getting it setup right to stop all the linker errors. But now I still have this left over and I am not sure of the best approach to fix it, could use some help.

C++ 模板提示：
#ifndef __MY_CODE_eg #define __MY_CODE_eg // your code // here. #endifC++ Templates hints:
#ifndef __MY_CODE_eg #define __MY_CODE_eg // your code // here. #endifMS 的 ATL/MFC 标头和 HL2 SDK 都包含类模板
CThreadLocal。如果您按照正确的顺序包含这些标头，即首先包含 ATL/MFC 标头（或包含它们的标头），然后包含 HL2 SDK 标头，则 HL2 SDK 应该通过
#ifndef __AFXTLS_H__。Both MS' ATL/MFC headers and the HL2 SDK contain a class template
CThreadLocal.If you'd include those in the right order, i.e. ATL/MFC headers first (or the headers which include them), then the HL2 SDK headers, the HL2 SDK should handle that problem via an
#ifndef __AFXTLS_H__.
