Qt app for windows XP

That misbehaved update from Microsoft last year which caused the sprintf_s error, it seems not to have touched msvcrt.dll directly, but rather some other files, but msvcrt.dll got the raw deal :-(
msvcrt.dll is somewhat of an unwanted child from Microsoft's point of view, for example here's what Raymond Chen writes: https://devblogs.microsoft.com/oldnewthing/20140411-00/?p=1273

@LeLev Don't forget that line in your .pro file:
QMAKE_LFLAGS_WINDOWS = /SUBSYSTEM:WINDOWS,5.01P.S. Just tried an empty vanilla Qt 5.6.3 MinGW49_32 QtQuick QML project (where you see Hello World in the middle of 640x480 window. Built on Windows 10 and tested on Windows XP, worked fine without that sprintf_s error, the msvcrt.dll on that Windows XP has version 7.0.2600.5512.
Anyway, since MSVC2013 is Microsoft own stuff, it's more likely to survive as the years go by :-)

That line is only applicable if you use the MSVC2013 compiler
Edit: to satisfy both compilers, we can use a prefix, change the line to
win32-msvc:QMAKE_LFLAGS_WINDOWS = /SUBSYSTEM:WINDOWS,5.01 -

apparently qt-opensource-windows-x86-msvc2013-5.6.0 that i just installed doas not configure kits automatically,
i have no compiler and no debugger in the kit, so i cant compile the project
do i have to download the compiler separately ? i dont see it in my qt 5.6 install dir C:\Qt\Qt5.6.0\5.6\msvc2013\bin nor in C:\Qt\Qt5.6.0\Tools\
compiler column is empty here..

If, after you've installed MSVC2013, you cannot persuade Qt to recognize that compiler/kit, one workaround is to uninstall Qt 5.6 MSVC2013 and then install it in Qt again.

Thank you so much!
my application now works on XP.
all i have to do now is re-write most of the qml code because i have to switch from qt quick controls 2 to controls 1 -

wrote on 8 Jun 2020, 13:20 last edited by@hskoglund good, maybe i will try it. But i already adapted everything to work with controls 1
thank you for the information.
Right now im trying to "optimize" some things because the application is very slow on the XP, i guess it will be even slower if i use controls 2
