it's my first time to try QT Creator on my Windows 8. But the problem is, it doesn't detect an existing compiler. My question is how can I add a compiler to get me started? Any ideas? Thanks.
If you're asking about how to add a compiler/kit (aka tool-kit, aka tool-chain) you can find it on a website called stackoverflow. =)
All kidding aside, you may need to download a compiler such as MinGW or Visual Studio Express.

Hi I have a debian image on BBB I have already installed QT creator on B^3 but the problem is whenever I try to start a new project in qt creator, couldn't see any option of kit. Infact when i add qmake and compiler path the application throws error.
What can I do to solve the problem. Can i directly get the full pack of SDK from qt.io/download ?
You must compile Qt libraries for your device (BBB) on your own, using specified compiler. You can find more information on this topic, here:
Qt Cross-Compilation Options
As soon as you compile Qt libraries for your device, you must move them to appropriate directories (on your BBB).
First, I would suggest learning to cross-compile, it's much faster & more easily maintained when you want to move to new versions. There's a ton of documentation and community around doing this. Windows & Linux both of which are probably dated, but info is still relavent. I've heard it's much easier from a linux host, but that could be biased.
That being said, if you don't want to cross-compile I believe you can simply install the qt embedded libraries. This question may offer some good advice. Once you have the libraries installed, you should be able to use qmake directly to create the Makefile for your project, then you can use cmake, or g++, etc.. to do the actual compiling.
You're likely going to work in command line though, I'm not sure you can run QT Creator on the BBB directly. I could be wrong.
There is an Example tab at the Qt Creator(2.6.1)'s Welcome page, which is supposed to show the already made Qt Project Examples. But whenever I click on that, Qt creator closes automatically. Sometimes it shows the Example projects for 1 or 2 seconds and the exits. Any idea?
You probably need to configure Qt Creator to find your Qt installation.
Compiler configuration for Qt Creator
And you might need to get the msvs compiler, too.

They now have the mingw version available for windows with Qt 5.0.2.
http://qt-project.org/downloads
Also if you installed Qt without the examples that may also cause this error.
Hope that helps.
I am new to Qt and its IDE Qt Creator so pardon my ignorance.
When I try to compile my code I get the exception
"Qt Creator needs a compiler set up to build. Configure a compiler in the kit options".
I have installed MingGW for compiling C++ code.
However, I am having a problem configuring it for Qt Creator.
Any help will be appreciated. Thanks
I suspect you are using the new 5.0 Qt. It required a bit of prodding for me too.
If you look into Settings > Build & Run > Kits you should see an auto-detected entry which will probably have an exclamation mark in front and is not editable. Ignore this.
Add a new Kit
Give it a name, set the "Qt version" and select a compiler. (Compilers should have been auto-detected. If you do not see any compilers, you will have to set at least one up manually)
Click the "Make Default" button. (You may have to modify project build settings to use the new Kit too)
There may be a better way, but I do not know it. And you should probably use 4.x until 5 is out of beta.
I was also having the same problem, so what I did was this:
sudo apt-get install g++
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev
I then closed the QT Creator, restarted it, and it worked.
I do not know which of the above two made it work, but it worked!
You are using Qt Creator 2.6.x, as those are the only ones that have kits.
Please go to Tools>Options>Build & Run>Compilers and add you mingw compiler there. You need to point creator to 'g++' in your mingw installation.
Then head over to the Kits tab and click on the desktop kit that creator should have created for you. In the details there is a field called Compiler (or Tool chain, don't remember). Select your mingw compiler there. Check the debugger field. If it is empty or using the gdb debugger that is part of mingw: Grab a debugger from http://builds.qt-project.org/, install it and point creator to that one. The debuggers delivered as part of mingw are known to not work well with creator.
Do not use the Nokia Qt SDK: Everything in there is terribly outdated by now!
This is just a starting point to troubleshoot your question, but the Qt Creator preferences has settings in the "Build & Run" area where you can define the location of your build toolchain: compiler, Qt version to build, etc. For mingw you'd have to point the right field to the location of g++, for a Qt version the location of qmake.
Not always the last version is the better. If someone is learning Qt to implement production solutions, is not good idea to use Qt version 5 (see the Qt5 change log). If you want to learn Qt programming, I think that the Nokia SDK is a good starting point, because you only have to install it as another Windows software, and start to coding.
By using linux is another good starting point, because you will have all the develop environment with a few apt-get commands.
When I started programming Qt, I lost a lot of hours to get a complete environment working with QtCreator, and I understand that not everybody has time for it.
I am using Qt Creator 3.5.1 based on Qt 5.5.1. The error "No compiler set in kit" has been a problem every time I have to configure a development system. The solution that worked for me is to select Tools/Options/Compilers and add a compiler. In my case a GCC compiler with Name:g++, Compiler path:/usr/bin/g++. The trick is to add the compiler before trying to add a Kit. If I add a Kit before I add a compiler I can never add the compiler to the Kit. If you having this problem delete the Kit, add a compiler, then add the Kit.
In your questions you must provide us more information about your problem, such as what versions of software are you using.
About your question, I think, that very good idea to you (as a beginner) is to use all-in-box QtSDK (link, need registration). There are ready-to-use QtCreator, MinGW and litle bit old Qt Libs in that QtSDK 1.2.1. So, you dont't need to configure it at all.
Hope, it'll help. Good luck!
I just installed qt creator sdk and the windows debug thing. When I try to debug the debugger comes with the warning:
Preferred debugger engine for debugging binaries of type 'x86-windows-msys-pe-23bit' is not available.
The debugger engine Cdb engine will be used as a fallback
Details: There is no gdb binary available for binaries in format 'x86-windows-msys-pe-32bit'
Then the program start building.
When I set breakpoints into the program the debugger won't stop at de breakpoints. I've tried a lot of things to let the debugger work properly but nothing has helped so far. If anybody has a suggestion please let me know. I think it maybe has something to do with the compiler I'm using which is something like mingw but i have no idea how to set another compiler or something like that
Since you do not know msys, most likely you do not need the msys compiler, try mingw compiler itself from here.
make sure to install gcc, and gdb.
Since you did not mention I assume it is Windows, as a side note, if gdb gave you headache on Windows please use the mingw version bundled with Code::Blocks it is probably older though (look for the one that comes with mingw bundled).
You need to get either gdb/cdb installed with Qt to be able to debug your code. Try editing the options in Tools->Options in Qt Creator and pointing to correct gdb paths. That should solve this problem. There are other options available there to configure the gdb options in the settings dialog.
I have multiple installations of Qt4 on my Windows XP SP2 machine and have installed Qt Creator 2.1 today. However, running the project (.pro) files spawns the oldest version of Qt Designer installed (the one installed in 2009 together with the rest of the framework).
Since
I would not like to remove any previous installations of Qt
and for some obscure reason even if I explicitly ask Windows Explorer to always use the version I need it does not
I would like to give up a bit and just sript the needed behaviour in a .bat file like:
e:\path\to\qtcreator.exe %1
This opens Qt Creator, but something seems to prevent it from treating the .pro file properly (in short, the project does not "open" as it should).
Qt documents have a page on the matter at Qt Creator: Using Command Line Options, but it seems to ignore the topic in question.
Since Qt (being as excellent framework as it is) is also known to have its quirks (like that of qmake), I wonder, may be there is an undocumented way to solve my problem?
(Another way to fix the thing would of course be to make the correct version of Qt Designer run, but frankly I'd prefer the "hard-wired" solution since the mechanisms provided by Qt itself are still a bit unreliable.)
The libraries and tools used for a particular project (and a configuration in it) is set in the Projects panel in Qt Creator:
http://doc.qt.io/qtcreator/creator-build-settings.html
Selecting the Qt version to use with a project should force it to run the Designer that's part of the version. If it doesn't, then you should report it as a bug.
