Scott Cantor updated XERCESC-2033: ---------------------------------- Assignee: (was: Scott Cantor) > Define _WIN32_WINNT for min supported version of Windows > -------------------------------------------------------- > > Key: XERCESC-2033 > URL: https://issues.apache.org/jira/browse/XERCESC-2033 > Project: Xerces-C++ > Issue Type: Improvement > Components: Build > Affects Versions: 3.1.1 > Environment: Windows > Reporter: Lee Doron > Priority: Minor > Original Estimate: 1h > Remaining Estimate: 1h > > Microsoft makes changes to the Windows API with each OS release. These > changes are reflected in the Windows SDK header files, which contain > conditional code according to the minimum version of Windows you wish to > support. This can be selected by defining preprocessor symbols -- see > http://msdn.microsoft.com/en-us/library/aa383745.aspx. The macro _WIN32_WINNT > is sufficient, or for finer granularity (by service pack), you can also > define NTDDI_VERSION. When you don't define these, they get set in > sdkddkver.h to the latest version supported by the SDK; for VS 2012, that's > Windows 8.0. If you use any APIs that have changed in recent versions, then > the DLL might not work properly with older versions of Windows (e.g. XP). > I haven't actually seen any failures with Xerces, which is why I didn't mark > this as a bug, but I think you should add this symbol to the preprocessor > definitions to be on the safe side. I did it quickly in the Visual Studio > configuration, or it could be done in the source code before including > <windows.h>. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: c-dev-unsubscr...@xerces.apache.org For additional commands, e-mail: c-dev-h...@xerces.apache.org
