Description
I got Gcc11.2 from winlibs.com，While configuring qt5.15.2 I got errors:
D:/QTFOlder/qt5/qtbase/src/corelib/io/qfilesystemengine_win.cpp:669:16: error: redefinition of 'struct _FILE_ID_INFO'

Follow the error message I found
\qtbase\src\corelib\io\qfilesystemengine_win.cpp
#if defined(Q_CC_MINGW) && WINVER< 0x0602 // Windows 8 onwards typedef struct _FILE_ID_INFO { ULONGLONG VolumeSerialNumber; FILE_ID_128 FileId; } FILE_ID_INFO, *PFILE_ID_INFO;
\qtbase\src\corelib\global\qt_windows.h
#if defined(Q_CC_MINGW) // mingw's windows.h does not set _WIN32_WINNT, resulting breaking compilation # ifndef WINVER # define WINVER 0x601 # endif # ifndef _WIN32_WINNT # define _WIN32_WINNT 0x601 # endif # ifndef NTDDI_VERSION # define NTDDI_VERSION 0x06000000 # endif #endif #ifndef NOMINMAX # define NOMINMAX #endif #include <windows.h>
windows.h was included after the WINVER defintion in qt_windows.h. But in fact the _WIN32_WINNT was set to 0x0A00 in _mingw.h which has been included in mingw's windows.h。
so I include windows.h before winver definition in the file , it seems work but i'm not sure.
#include <windows.h> #if defined(Q_CC_MINGW) // mingw's windows.h does not set _WIN32_WINNT, resulting breaking compilation # ifndef WINVER # define WINVER 0x601 # endif // …… //#include <windows.h>
