Compiling Qt Creator for Qt 5.0.1 for Windows 7 64 bit using MinGw...
-
@Tobias can you please reply about my querries?
Thank You. -
I am having the exact same problem. Can someone please guide us here?

Hi,
Which part of the problem are you having?
If you download and install "Qt 5.1.1 for Windows 32-bit (MinGW 4.8, OpenGL, 666 MB)" from http://qt-project.org/downloads you should get the Qt 5.1.1 libraries (32-bit), the Qt Creator 2.8.1 IDE, and the MinGW 4.8 compiler all set up automatically.
If you want the 64-bit libraries instead, you need an unofficial package. Download "x64-Qt-5.1.1+qtcreator-2.8.1" from http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/Qt-Builds/ and follow the instructions at the bottom of the page.

Thanks very much! It all works now :)

Hi LKSH,
I dont understand why traditionally there has been no official 64 bit build?
Neither Nokia did it nor is Digia doing it.
I am a bit skeptical about using non-official builds, that is why.
Any idea? -
Hi CAD_coding,
Here is a list of possible free (LGPL) packages (not sure about iOS though):
- MSVC 2012, ANGLE, 32-bit
- MSVC 2012, OpenGL, 32-bit
- MSVC 2012, ANGLE, 64-bit
- MSVC 2012, OpenGL, 64-bit
- MSVC 2010, ANGLE, 32-bit
- MSVC 2010, OpenGL, 32-bit
- MSVC 2010, ANGLE, 64-bit
- MSVC 2010, OpenGL, 64-bit
- MinGW 4.8, ANGLE, 32-bit
- MinGW 4.8, OpenGL, 32-bit
- MinGW 4.8, ANGLE, 64-bit
- MinGW 4.8, OpenGL, 64-bit
- Linux 32-bit
- Linux 64-bit
- Mac 32-bit
- Mac 64-bit
- Android on Windows, 32-bit
- Android on Windows, 64-bit
- Android on Linux, 32-bit
- Android on Linux, 64-bit
- Android on Mac, 32-bit
- Android on Mac, 64-bit
- ? iOS on Windows, 32-bit
- ? iOS on Windows, 64-bit
- ? iOS on Linux, 32-bit
- ? iOS on Linux, 64-bit
- iOS on Mac, 32-bit
- iOS on Mac, 64-bit
(Bold = Official package)
Don't forget, Digia supports 6 commercial platforms too: Solaris, Embedded Linux, Windows Embedded, Green Hills Software INTEGRITY, QNX, and VxWorks.
Each package takes a few hours to build. Each package needs to be tested by many people, over many days, to ensure that bugs are minimized. It's impossible to test so many packages, so Digia needs to choose a few to produce.
Windows is actually very well-covered, having 7 out of the 12 official packages. 32-bit packages work fine on 64-bit machines.

Sorry to not mention this previously but I was speaking about the MinGW version.
MinGW 4.8, OpenGL, 32-bit as you said is available, but no 64 bit official build. -
[quote author="CAD_coding" date="1380981170"]Sorry to not mention this previously but I was speaking about the MinGW version.
MinGW 4.8, OpenGL, 32-bit as you said is available, but no 64 bit official build.[/quote]Yes, I know you were asking about the 64-bit MinGW build.People can ask, "Why didn't Digia create an official 64-bit MinGW package?" or "Why didn't Digia create an official 64-bit MSVC 2010 package?" or "Why didn't Digia create an official 32-bit Mac package?"
The answer in engineering terms is, "Because Digia is managing the "Project Management Triangle":http://programsuccess.wordpress.com/2011/05/02/scope-time-and-cost-managing-the-triple-constraint/ "
There are 3 constraints:
- Scope: There needs to be official builds for every platform that Qt supports. Each release should also have a good number of new features and bug fixes.
- Time: Each official build increases the time needed to integrate every new feature and every bugfix. Each official build also increases the time needed to do alpha, beta, and release-candidate testing. But, everyone also wants new Qt versions released regularly, and released on schedule.
- Cost: More official builds require more hardware for testing (which cost money to acquire, run, and maintain). Longer development/testing times also mean that employees need to be paid more for each Qt release.
As part of the effort to balance all these requirements and constraints, 64-bit MinGW (and 64-bit MSVC 2010 and 32-bit Mac and many other) builds were left out.
But that's not a big issue, because your core requirement is:
[quote]I want Qt Creator which can compile 32 & 64 bit applications[/quote]There are 3 options that can meet that requirement:- Use the official 64-bit MSVC 2012 build
- Use the unofficial 64-bit MinGW build
- Build your own 64-bit MinGW build
You said you don't want to rely on MSVC, and you're skeptical about unofficial builds. Why?
Please go through a proper selection process and choose that best option for you.

Hi,
I am new to Qt, and in way over my head, but could someone maybe explain how to use the second option listed above? "Use the unofficial 64-bit MinGW build"
I've downloaded and installed this:
x64-Qt-5.1.1+qtcreator-2.8.1-(gcc-4.8.1-seh-rev5)
I found the qtcreator.exe and I have Qt running. I tried to open a project I created in my other "legit" Qt installation. I am seeing the message "No valid kits found". I think I need to point Qt at the 64 bit minGW compiler, but I can't figure out how to do that. Anyone?
(PS: I got into all this because I want to use a package called openCV to write .avi video files...)
thanks

Hi johnLIC,
Qt 5.1.1 is very old now. Get Qt 5.2.1 instead from http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/Qt-Builds/
To set up your tools,
See "Adding Compilers":http://qt-project.org/doc/qtcreator-3.1/creator-tool-chains.html to tell Qt Creator where to find your compiler
See "Adding Qt Versions":http://qt-project.org/doc/qtcreator-3.1/creator-project-qmake.html to tell Qt Creator where to find the Qt binaries
Finally, see "Adding Kits":http://qt-project.org/doc/qtcreator-3.1/creator-targets.html to tell Qt Creator how to combine your compiler with the Qt binaries.
You might also need to run the qtbinpatcher tool (go to http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/Qt-Builds/ and read the first section underneath the downloads list). I haven't used the unofficial packages myself, so I'm not 100% sure.
