I am a Total Noob at this and I know nearly nothing about this.
I just started using Qt Creator for windows 5.6.0 and While I wrote my first "Hello World" code..
I was asked to add a kit. I searched the net for similar issues and it said that I needed a compiler for Qt. Thus, I installed MinGW from QtForums
now when go to Tools->Options->Build&Run->compiler, I can not understand how do I add it to the list.
Please help me through it?
To just get started the easiest thing to do would be to go here:
Link to Qt downloads page
Scroll down and select Qt 5.6.0 for Windows 32-bit (MinGW 4.9.2, 1.0 GB) this will download the installer (its about 1 GB). Run it and choose all the default options. Then you will have Qt 5.6 with mingw and Qt Creator all setup ready to go.
Note: Before you start that its probably best to delete your current version - if you are not attached to it in any way :)
If you want to fix your current setup, then it might be longer-winded to find out what you are missing for mingw. For example you need the mingw qmake file that would be located here (using default install options):
C:\Qt\Qt5.5.1\5.5\mingw492_32\bin\qmake.exe
to create your "Qt Version" part of the kit. And the actual mingw compiler, which is located here (using default install options):
C:\Qt\Qt5.5.1\Tools\mingw492_32\bin\g++.exe
to create your compiler. Once you have both of these then you can put them together to create your new kit.
But to just add a compiler all you need to do is:
Click compilers tab
Click add and select mingw
A new compiler is added, click it
You will see some options below, add your compiler executable path in (like the one above for example).
And you are done - there are some other options, but you probably don't need to use them.
note my paths are for qt 5.5.1 (obviously) so slightly different to 5.6 :)
update
Its all been moved around! - here are the new paths:
offline-installers
old-version-archives
Well. I was unable to provide the data before but it all makes more sense now.
What I had installed was Qt for windows 64-bit (vs 2013, 836mb).
Hence, Instead of MinGW, I have msvc2013_64. It does have qmake.exe but doesnt have g++.exe. And I had downloaded it separately.
You're answer was very helpful.
Added MinGW packages to QT installation with the QT Maintenance Tool (C:\Qt\MaintenanceTool.exe)
It allows to add/remove components via the qt repositories. So no need for re-installation.

I have a project written in Qt that I have no problems compiling and running on Linux. The command line is:
qmake ../trunk/GSDTesting.pro
The process on Linux was really simple: install a few dependencies using apt and you are off.
My task is to recompile the same program on Windows using Visual Studio C++ compiler, but the problem is I don't know how to start. There is no such thing as qmake for Windows.
Can someone give me a few hints where to start. Please note that I don't know QT almost at all, my task is just to debug some issue unrelated to QT.
Are you using terminal exclusively on Windows? If so, maybe this image of example build steps straight from Qt Creater 4.14.2 may help you:
As you can see the image of the default Qt creator build steps list the file path where 'qmake.exe' can be located on a local installation of the toolchain.
If you can use a machine with a display I find using the Qt creator GUI is not all that bad.
Here is a link to the base get started page:
https://doc.qt.io/qt-5/gettingstarted.html
Here is a link to the installer download page:
https://www.qt.io/download
IMPORTANT:
You will need to make a Qt account, login to your account, and then download the open-source version of the API. The commercial version of the same source is acquired differently/seperately.
Otherwise, if you cannot use the GUI, can I request some clarification on why you cannot use Qt creator on your Windows installation?
I've just switched to QtCreator for C and C++ developing. I have problem in creating first project, in particular with compiler kits I suppose.
When I go to create a new project, I have the error message that no kits is available.
As you can see, I don't know why it is shown that Qt Version is invalid. How could I solve?
You should first install your C++ compiler. You should also define your compiler in "Compilers" section. If you also want to use Qt you should set the compiler for your kit in the "Kits" section.
When you install QtCreator on MAC OS X you can find it in
/applications/qt
in this folder there is another folder called
5.2.1
Here there are all the compilers.
So to solve the issue you can either add, in QtCreator options, the path of every qmake.bin file or cut the 5.2.1 folder and paste in
/Users/YOURNAME/qt
creating qt folder if it doesn't exist.
PS: I've tried to make the directory invisible, but if I do so, I get errors using the second method
I recently installed Qt creator 2.8.1 online on my win Vista 32 bit machine.
To start with Qt I wrote simple pushbutton code. And when I tried to build it shows error message saying
Qt Creator needs compiler set up to build. Configure a compiler in kit
option
I tried with that Kit option din't work. what do I do?
PS Thank You
Simply refer to MINGW online install available at Qt's official downloads( http://download.qt-project.org/). You need not do anything. It will automatically detect an kits and will compile successfully.
I'm trying to use Qt4 using the Code::Blocks IDE. I'm running Linux Mint and I'm getting some errors. I looked around and found some people that had the same problem as me, but I can't seem to get their solutions working on my computer.
I installed Qt4 using the command
sudo apt-get install qt4-dev-tools
And when I type whereis qt4, I get qt4: /usr/lib/qt4 /usr/include/qt4 /usr/share/qt4
If I select "Create new Projet" in Code::Blocks and Select Qt4 project, it asks for Qt's location, which is $(#qt4) by default. If I click next, it says Code::Blocks doesn't know the "qt4" variable and gives me a prompt to set the base location, the include directory, etc.
Since I don't have any idea as to what I should be putting in there since nothing works (either it says "QTCore cannot be found in the specified directory", or the "lib" directory couldn't be found, etc.).
I tried what was posted on this forum: http://crunchbang.org/forums/viewtopic.php?id=18210, but it didn't solve my problem and I get the same errors.
In the "/usr/share/qt4" directory, there's a link to the "include" directory, but not to the "lib" directory.
I'm pretty new to Linux and all of this, so I'd like it if the answer was very detailed explaining what I did wrong / what I have to do.
Install the QtSDK
As a first step I would advise you to download directly the QtSDK, from the project site here.
Note: You could also use the precompiled version for your Mint version,
but in my personal experience, when working with external SDK,
you have more independence in development, it also allows you to work
freely with multiple versions of Qt simultaneously without move any
dependence of your OS.
You can follow the graphics steps to install the SDK, I advise you to check the option "download source", later this is going to be used for debugging code, and if necessary will allow the recompilation of some classes.
Now your QtSDK is installed on the folder eg "/usr/local"
So, all references inside your IDE should refer to this location.
Install the C::B
You can use the version available in "Software Manager"
Configure the C::B
When we start a new project and asks the location of our SDK we indicate this directory /usr/local/QtSDK/Desktop/Qt/4.8.1/gcc
Now the project is ready!
Note: "/usr/local" and "4.8.1" are variables depending on where
and what version you have installed.
Is very likely that your build directory, is not correctly assigned in "Settings->Compiler and Debugger->Toolchain ...->Compiler's Directory"
will be the default "usr" which should be replaced by "/usr/bin"
Now, when compiling with the standard project ".pro" and if your project has the requirement to use a "moc" tool strategy, the simplest way to do that, is use a customized Makefile, with all stages of compilation.
To learn how to make a customized makefile, you can read this answer.
And although I would advise again:
Although that CB is an optimal environment for working with wxWidgets, and C/C++ in general, I personally think that in the case of working with Qt, QtCreator provides a development environment more native and optimized to work with your projects QT.
I had a working C++/Qt application. I updated MinGW, Qt and Qt Creator to the latest versions, and now I get an error at compile time. This error does not seem to be due to my code, but to the build system.
E.g.:
17:11:15: Running steps for project MyTest...
17:11:15: Starting: "C:\Qt\qtcreator-2.6.0\bin\jom.exe" clean
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
17:11:20: The process "C:\Qt\qtcreator-2.6.0\bin\jom.exe" exited with code 3.
In the project settings there is the message "qmake: No Qt version set. Cannot run qmake."
My source code is just what you get automatically when you create a new application.
I updated the system environment path with the new Qt and QtCreator directories.
I do not know what else to do...
Thank you!

MinGW
Qt 4.8.4
Qt Creator 2.6.0 (based on Qt 4.8.3 32 bit)
Please go to Tools->Options->Build & Run->Kits and check that there is a Qt version set up in the kit you are using.
If not, then check the Qt versions creator detected in Tools->Options->Build & Run->Qt versions. Is the version you want to use there? If not: Add it here.
Then return to the kits page and set one of the kits to use that version. Double check the other information while there.
Now you should be able to build your project. You might need to close/reopen it though.
Initial setup seems to be a bit bumpy... but it works really well once you get over that initial hurdle:-( There are quite some improvements in the next update for this. Check the Qt 5 RC2 packages, the creator included there already contain most of the fixes if you are curious).
