[SOLVED] Qt5 + VS2010 QDateTime => not enough actual parameters for macro 'min' & 'max'

MaximAlien · wrote on 12 Jul 2013, 17:52

Defining like that:
@#define NOMINMAX
#include <windows.h>@
doesn't help me. Can you help me guys?

I have compilation errors in:
@static inline qint64 nullJd() { return std::numeric_limits<qint64>::min(); @

I have 2 windows.h includes in other classes.

MaximAlien: have you tried "/DNOMINMAX"?

or DEFINES += NOMINMAX with qmake?

Thanks for help Laszlo! Defining @DEFINES += NOMINMAX@ in pro file helped me.

Use this include "#include <*qt_*windows.h>" instead of #include <windows.h>

@sdolard: that will not ultimately help.

Also, not sure what you mean by stars in there.

@Laszlo Papp
Sure, but qt_windows.h already include a define for NOMINMAX, and other stuffs. So it's better to use it.

Chars between * should be bolded.

sdolard: the problem is that, it does more than what you need, so not compact enough. :)

More importantly, you need to find and maintain the right place for the include. If you do it in the build system, it always works.

Also, even though qt_windows.h is installed publicly, you could include anytime. However, if you wanna be nice, you would use qt win ifdefs around just in case, but then it is getting uglier. :)

But yes, provided those drawbacks are not real problems, that also works.

Hi,

I have the same problem, but without an include of windows.h. So I can not enter a define before it and including
DEFINES += NOMINMAX
in the pro-file did'nt worked either.
Any more ideas?

Hi,

since I started the project I had to reinstall windows and so qt creator. Originaly i used mingw. Now I also installed mingw, but somehow the installation was not compleat and qt creator used msvc instead. After swiching back to mingw I got rid of the error. So it's solved for me, but others might have the same problem.

This worked to me for Qt5.5 VS2010
