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

[iphenion]

Yes, still the same problem here: Qt5.0.2 32bit MSVC2010

[djszapi]

Hitting with 5.1.0 RC2 as well. I am using 32 bit MSVC2010 and the default variant (angel?).

Did you try switching to VS2012? I encountered the same problem

[Violet Giraffe]

You should define NOMINMAX when including <windows.h>. Period. And WIN32_LEAN_AND_MEAN, by the way.

[djszapi]

@MaximAlien: Nope, the customer was stuck to 2010.

@Violet Giraffe: yes, it was mentioned above what to do, so we are aware of that. However, it would be nice to fix centrally in the Qt Project if possible. If not, it would be nice to be aware of the limitation why it is not possible.

[MaximAlien]

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.

[djszapi]

MaximAlien: have you tried "/DNOMINMAX"?

or DEFINES += NOMINMAX with qmake?

[MaximAlien]

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

[sdolard]

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

[djszapi]

@sdolard: that will not ultimately help.

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

[sdolard]

@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.

[djszapi]

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

thx.

[frankiefrank]

This thread helped me out with this issue. THANK YOU.

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?

[DimitriJunker]

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
