How to increase available RAM for Qt Creator?

[fezvez]

Hello,

I'm trying to create a program that needs more than 4 gigas of RAM. With Visual Studio, I managed to do it (Properties/Linker/System/Enable large adresses) and I can fully use 5 gigas of RAM.

Is there anything equivalent with QtCreator? Because I'm stuck with around 2 gigas of RAM. (there's a std::bad_alloc() at around 2.5 gigas)

Unfortunately, for my program, I'll be needing as much RAM as I can (let's say 16).

And, I've tried to Google it / search on QtCentre, but I couldn't find anything.

Thanks in advance!

Add "-Wl,--large-address-aware" to your linker flags. I don't know how you were looking for it, it took me 20 seconds to find it through Google.

Well, what a shame, I really couldn't find anything (still can't find anything though) Your searching skills must be much better than mine!

Seriously, on Google, "qt creator windows increase RAM" doesnt not link to anything relevant... except that now it points to this topic!

Thanks a lot!

Edit : How awful... I can't find a correct answer to this simple question : how do I add arguments to Qt Creator Linker? This doesn't help : the arguments seem to be ignored (I still have a std::bad_alloc())

You didn't find anything because it's nothing to do with Qt Creator as it's just an IDE (or fancy text editor putting it another way). The compiler used is GCC, so you need to lookup the options for that.

Same goes for the Linker, nothing to do with Qt Creator. You'll need to look at your .pro file which is used by qmake. The first search result is therefore quite useful: http://doc.trolltech.com/latest/qmak...reference.html. Have a look at QMAKE_LFLAGS for example.

I was searching for "mingw enable large addresses equivalent" or something like that.
