Hello, Qt not work with minwg64, few function will be corrected.
For example:
cd src\winmain\ && C:/mingw-w64/bin/mingw32-make.exe -f Makefile
mingw32-make.exe[1]: Entering directory `C:/qt-mingw64/src/winmain'
C:/mingw-w64/bin/mingw32-make.exe -f Makefile.Debug all
mingw32-make.exe[2]: Entering directory `C:/qt-mingw64/src/winmain'
g++ -c -g -Wall -frtti -fexceptions -mthreads -DQT_THREAD_SUPPORT -DUNICODE -DQT_LARGEFILE_SUPPORT -DQT_NEEDS_QMAIN -DQT_NO_CAST_TO_ASCII -DQT_ASCII_CAST_WARNINGS -DQT3_SUPPORT -DQT_MOC_COMPAT -D_USE_MATH_DEFINES -I"..\..\include" -I"tmp" -I"..\..\include\QtCore" -I"c:\qt-mingw64\include\qtmain" -I"tmp\rcc\debug_shared" -I"tmp" -I"..\..\include\ActiveQt" -I"tmp\moc\debug_shared" -I"..\..\mkspecs\win32-g++" -o tmp\obj\debug_shared\qtmain_win.o qtmain_win.cpp
