Qt Forum: Qt 5.6 doesn't compatible with Windows XP
Qt Documentation: Targeting XP with Visual Studio 2012 and later
if you try build Qt again, but this time with DirectWrite disabled (as in 5.5) then you should be fine in Windows XP:Code: Select all
configure -debug-and-release -opensource -confirm-license -mp -icu -openssl -nomake examples -nomake tests -target xp -skip qtwebkit -no-directwrite
Qt Documentation: Targeting XP with Visual Studio 2012 and later
Visual Studio 2012 and later do not support building for Windows XP out of the box. However, support for targeting XP was added in an update of Visual Studio 2012. This works also with Visual Studio 2013.
