[Qt-creator] Optimizing for speed
Dear All, I am new to qt-creator, and I am using it mainly to write my C++ programs on a Linux machine (Fedora 12). Basically, my projects are "Empty Qt4" ones. My question is: how can one configure qt-creator for optimizing for speed the C++ programs edited with qt-creator?

Re: [Qt-creator] Optimizing for speed
On Linux, it uses -O2 by default in release mode if I recall correctly, so it already is. /s/ Adam On Sat, Dec 19, 2009 at 5:46 PM, Paul Smith wrote: > Dear All, > > I am new to qt-creator, and I am using it mainly to write my C++ > programs on a Linux machine (Fedora 12).

Re: [Qt-creator] Optimizing for speed
Thanks, Adam. I was thinking about the option -O3. How can one force qt-creator to use -O3?

Re: [Qt-creator] Optimizing for speed
This is really a qmake question, since it's qmake that controls this. In your .pro file, use something like: QMAKE_LFLAGS -= -O2 QMAKE_LFLAGS += -O3 /s/ Adam On Sat, Dec 19, 2009 at 6:38 PM, Paul Smith wrote: > Thanks, Adam. I was thinking about the option -O3.

That's not needed, just use the qmake from that directory.
