Qt x64
Message 1 in thread
Hello !
I would like to compile Qt with a 64 bit compiler. The reason is that I
use 64bit programming for image processing for my thesis, because I have to
load and manage large images stacks (> 3G0). Is it possible under Windows
x64 ? Under Linux x64 ?
I'm actually working under Windows 64 and I use the last version of Qt Open
Source, i.e 4.2.2

Qt has supported 64-bit platforms for years. I have not tried it in 64-bit
Windows but its use is commonplace in 64-bit Linux.

Yes, of course it is possible. Windows 64-bit with open source Qt, not
sure. Should work if you get a 64-bit gcc compiler.
Linux on AMD64 works for a long time. Debian builds Qt on various
interesting platforms without problem [1], one of which is AMD64. You
can even get the build logs :) [2][3]

Yes it is possible. I am using the open source Qt on windows XP Pro X64 with
visual studio. Sometime back I even posted on the list how to get it to
work. If you need it, here's the link, just look at bullet point (1).

Ok. I tried to compile it under Windows x64 like writtent here (I had tried before that quite same solution http://arb.developpez.com/qt4/vc++/compilation/), it compiled correctly but I have still a question:
is it compiled in true x64 native code or is it WOW64 code (32-bit application compiled 64-bit but "still" 32-bit like) ?
The reason of my question is the quantity of memory allowed for each process
When I configure, it displays this:
QMAKESPEC...................win32-g++ (commandline)
Architecture................windows
Maketool....................mingw32-make
The cl.exe used is the true 64-bit compiler, and the code is compiled in 64bit. But I know that, depending on how it is compiled, you can have a 64-bit process running under Windows x64, but because running in the WOW64 config, 2Go mem only is allowed.

I am not sure abt that. I guess, it may be wow64, again not sure. Also since Qt(and VS 2005 ) is 64bit compatible, I am not sure if it automatically detects your system config. And the instructions don't have any reference to it too.

I patched the same and I'm compiling under the x64 environment. Just a little question:
is it compiled with this way in true x64 native or using WOW64 ?

It's 32bit as MinGW does not support Win64 for now.

Hi,
If you used VC++ with the true 64bit compiler, your code is true 64bits.
QMAKESPEC is set to win32-q++, but as you use Visual, it cannot be the
correct QMAKESPEC.
As for the maketool, it should be nmake - and it does not matter as the
make tool is not used for compiling -.
If you used cl.exe is 64bit mode, your code is 64bits, that's all.

Yes, I made the same reasoning because cl 46-bit is used, but I was not sure
100%. Thanks ! :)
