Qt app for windows XP

hskoglund

@LeLev Don't forget that line in your .pro file:

QMAKE_LFLAGS_WINDOWS = /SUBSYSTEM:WINDOWS,5.01

P.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 should be interesting reading for @LeLev !

hskoglund

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

a real nightmare the story of this dll, just like my day ^^

i have error in compilation output saying
g++: error: /SUBSYSTEM:WINDOWS,5.01: No such file or directory

if i add this to my pro file
QMAKE_LFLAGS_WINDOWS = /SUBSYSTEM:WINDOWS,5.01

hskoglund

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

oh ok! my bad, i was still trying with minGw

@hskoglund , @JonB

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..

@hskoglund ok i will download vs2013 and try to use the c++ compiler from it
thank you

hskoglund

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.

@jsulm @hskoglund @JonB
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

hskoglund

@LeLev Now there's one reason to try 5.7 instead of 5.6 (I use MSVC2013 with Qt. 5.7.1 for Windows XP) because I think qt quick controls 2 works in 5.7...

ODБOï

@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
