---------------------------------------
Thanks Alberto!
> XercesLib fails to link on Microsoft Visual Studio 7.1
> ------------------------------------------------------
>
> Key: XERCESC-1665
> URL: https://issues.apache.org/jira/browse/XERCESC-1665
> Project: Xerces-C++
> Issue Type: Bug
> Components: Build
> Affects Versions: 2.7.0
> Environment: Microsoft Visual Studio 7.1 "Enterprise Architect"
> Reporter: Rick Parrish
>
> Download 2.7.0 tarball; unzip source tree; open the
> \xerces-c-src_2_7_0\Projects\Win32\VC7.1\xerces-all solution in VS7.1; select
> build-all to build entire solution. The XercesLib library is successfully
> built but all of the demo projects that link to it fail. Sample error message:
> ------ Build started: Project: StdInParse, Configuration: Static Debug Win32
> ------
> Linking...
> xerces-c_static_2D.lib(BinHTTPURLInputStream.obj) : error LNK2019: unresolved
> external symbol [EMAIL PROTECTED] referenced in function "public: void
> __thiscall xercesc_2_7::SocketJanitor::reset(unsigned int *)" ([EMAIL
> PROTECTED]@xercesc_2_7@@[EMAIL PROTECTED])
> .\..\..\..\..\..\Build\Win32\VC7.1\StaticDebug/StdInParse.exe : fatal error
> LNK1120: 1 unresolved externals
> Examining the "SocketJanitor" class declared inside BinHTTPURLInputStream
> reveals that the reset function directly calls the WinSocket 2.0 API
> "clocksocket" function while the rest of the code calls a DLL thunk function.
> I presume the purpose of the thunking fuctions is to remove any direct
> linking dependency to the winsock library. However, directly calling
> "closesocket" in the helper class breaks that.
> Work around #1 - use a #pragma comment(lib, "ws2_32") to force linking the
> winsock DLL and supress the link error.
> Work around #2 - modify the janitor helper class as follows:
> Replace this ...
> void reset(SOCKET* p = 0) { if(fData) closesocket(*fData); fData=p; }
> ... with this ...
> void reset(SOCKET* p = 0) { if(fData && gWSclosesocket)
> gWSclosesocket(*fData); fData=p; }
> This also requires moving the gWSsocketclose declaration ahead of the
> SocketJanitor class inside BinHTTPURLInputStream.
