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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
