I want to use Qt Creator with MS VC++ 11 but it says there is no toolchain to build Qt.
I installed Qt with the full SDK installer.
What to do now?
Isn't MSVC++ 11 comes with Visual Studio 11? If so then Qt hasn't supported makespec file for that version AFAIK (correct me if I am wrong). But following are the (rough) steps for running Qt Creator with MSVC 2010 nmake/cl tool-chain..
Download Qt SDK 4.8.2 compiled using msvc-2010 toolchain from this site (second page).
Install MS VC++ 2010 free development tools (or full SDK), which comprises of nmake/cl/cdb executables.
Restart PC so as to initialize environment variable and all.
Start Qt Creator, by now you will notice msvc-2010 tool-chain has been identified by Qt Creator (Tools -> Options Dialog). If not then manually add it.
Also confirm that Qt version 4.8.2 of msvc-2010 has been identified in Qt Versions tab. If not then manually add it by giving path of qmake in bin of Qt SDK folder. It will also select msvc-2010 tool-chain automatically.
Here you go, now go to Projects and in Build Settings, select msvc-2010 tool-chain and compile. Make sure win32-msvc2010 is selected as makespec file.
Hope this helps.
try building using the makespec of Visual Studio 2010.
SET QMAKESPEC=win32-msvc2010
before running configure and qmake should do the job

I am building a GUI application in which I have to use Visual Studio 2010 build tools. I was told that the correct qt version to use with this VS version is 4.8. I've downloaded Qt 4.8.0 using this link:
https://download.qt.io/archive/qt/4.8/4.8.0/
And I made this version the default in the VS Qt options menu. However, when I try to create a new visual studio project, all of the module options are greyed out.
Which in turn makes it impossible to create the project because upon clicking "next", the "Finish" button is also greyed out. Any Idea of what's going on??
With pre-compiled binaries (that is, you don't have to compile qt yourself) you can use Qt 5.5.1 with VS2010 that you can get from here.
After that, i would create a simple project using qmake and specifying
TEMPLATE = VCAPP
that will tell the qmake (see docs) to generate a .vcprojx file that you can use from VS2010.
Latest Qt version that supports VS2010 is 5.6.3 IIRC, however mind you that even that version is now EOL. (March 2019).
You should try to upgrade to 5.9 or 5.12 (however i am not sure that VS2010 will be able to support those since they rely pretty heavily on c++11 that VS2010 supported very lightly)
P.S. If you'r stuck with Qt4 then greatest version is 4.8.7 (VS2010 supported) that you could get from here
I cant use std::wstring_convert in Qt 5.1, because it said me that <codecvt> : No such file directory. What can I do? I don't know... this code is working at the MSVC 2013.
QtCreator is just a front-end that allows you to edit your source files, it does not contain a compiler. On Windows you need either MinGW or Visual Studio to compile code.
If you want to use Qt 5.1 with Visual Studio 2013, you would have to compile Qt yourself. Digia provides builds for Visual Studio 2010 and 2012. You can find the latest version of Qt here or an old release here.
My advice would be to install Visual Studio 2012 and download a VS2012 build of Qt. Then go to Tools > Options > Build & Run > Kits, click the Add button on the right (or modify the existing one as it probably won't work anyway). Set the compiler to "Microsoft Visual C++ compiler 11.0 (amd64)" if you downloaded the 64 bit version of Qt or "(x86)" if you downloaded the 32 bit version.
Then set the debugger to cdb.exe and the Qt version to the one you just downloaded (if you don't see it, go to the Qt Versions tab at the top, add it, click Apply and the go back to Kits and it should be there). Click ok and your kit should be ready! Make sure that you don't have a warning signal that would point out a potential mistake.
Now open your project and go to the Projects tab (Ctrl + 5) and make sure your project is using the correct Kit.
You should now be all set up properly.
Additionally, if you don't want to install Visual Studio 2012 and want (or have to) work with VS 2013, you can use the Qt 5.3 BETA builds located here. Please note that these builds are in beta and shouldn't be used in production code, if you want to use VS2013 with Qt in production code I would recommend to build Qt 5.2.1 with VS2013, it's not that hard but it can take a while.
You are missing this in your project file:
CONFIG += c++11
You need to make sure that your GCC version (brought to you by mingw) supports that feature though. It is possible that you are using an old version where it was not supported.
I am new to C++ and have been working with MS VISUAL STUDIO 2010 Express. However, I am in need to shift to Qt as my university recommends. Unfortunately, the qt.nokia.com is redirecting to another site http://qt.digia.com/.
Since everything in that site is not free, I found the following link called "Qt Open Source Version". Is this is the site to download Qt?
When I go there, I can see various options, which means number of downloads. I have windows 7 ultimate and got visual studio 2010 express installed in my machine. But, this site got number of windows downloads. I prefer the one which claims to come with the Qt IDE (Qt Creator??). If you need further more information, I will be using this Qt GUI C++ applications with OpenCV.
I have already installed OpenCV and it works with VS so if you can, please tell me how to set it up with Qt as well.
Please help me to download the correct version of Qt. Thanks
Answering to these kind of question is always hard and dangerous!
I know you had experiences with VS but
I'm going to offer you to choose MinGW instead.
Download link
qt-project is the correct place to get open source Qt.
There are prebuilt binaries of Qt 5.0 for VS2012, but if you want to use Qt 4.8 with VS2012 you'll need to compile it yourself, as there are no prebuilt binaries for VS2012 (yet?). Compiling Qt is not difficult, just open command prompt for VS2012, run configure --help to find out how you can customize your Qt build. Then run configure with appropriate parameters, then nmake.
If you decide to use Qt Creator as an IDE you are welcome to do it - Qt Creator can compile projects using different compilers, including VS2012 compiler. But in order to debug projects compiled with VS2012 compiler you'll either need to use VS2012 or install Debugging Tools for Windows (which Qt Creator will find and use to debug VS2012-generated executables).

I am completely confused in installing Qt.
Do I need to download both Qt creator and Qt SDK or Qt.exe?
I have Visual Studio 2010 and Code::Blocksin my PC. So, how can I link if any one of the Qt XXXX listed above with VS-2010 or with Code::Blocks?
Please help
You can download QT creator from http://qt-project.org/downloads for windows you will get a .exe (you will find different .exe for VS Studio and mingw, so you can use what you prefer), once you install it you got
Qt libraries, prebuilt for a particular development platform (operating system
and compiler)
Qt Creator integrated development environment (IDE)
Basic development tools, prebuilt for a particular development platform
Documentation
Some more help.
You can start Qt Creator directly after the installation by selecting the option
on the last page of the installation program. You can start most of
the development tools, such as GUI designers, compilers, and debuggers
directly from Qt Creator. You can also access the installed documentation and
example applications from Qt Creator.
You can open most example applications in the Qt Creator Welcome mode to build
and run them. Additional examples can be opened by browsing
(install_dir)/(version)/(compiler)/examples.
To develop a Qt application, you need to set up a project. Qt Creator contains
wizards that guide you step-by-step through the project creation process. The
wizards prompt you to enter the settings needed for a particular type of project
and create the necessary files for you. To start, select File > New File or
Project.
The wizards create projects that use the Qt build tool, qmake. It is a
cross-platform system for build automation that helps simplify the build process
for development projects across different platforms. You can modify the build
and run settings for qmake projects in the Qt Creator Projects mode.
Qt Creator provides support for building, running, and deploying Qt applications
for different target platforms, or using different compilers, debuggers, or
Qt versions. Kits define the tools, device type and other settings to use when
building and running your project.
The Qt installation program adds the installed Qt version
((install_dir)/(version)/(compiler)/bin/qmake) to Qt Creator and creates a kit
that specifies the installed Qt version and compiler. To use the kit, add it for
your project in the Qt Creator Projects mode. Then select the kit in the Kit
selector before you build or run the project.
To compile C++ Qt applications by some other means, add
(install_dir)/(version)/(compiler)/include to your build tool's search path
for include files, and (install_dir)/(version)/(compiler)/lib to the search
path for libraries.
To work with Visual Studio 2010, you can download the installer "Qt 5.0.1 for Windows 32-bit (VS 2010, 481 MB)", or just download the source code and build it yourself (you'll need to do that if you want 64-bit versions of the libraries).
"Qt Creator" is Qt's IDE, so you don't need that. You just need the "Qt Library" to use Qt with other IDEs. For Visual Studio, you'll also want to download the "Visual Studio Add-in," which allows you to view Qt data structures in the debugger.
The free downloads are available at qt-project. Commercial downloads are on digia.
On my computer (Win7 32, VS2010 Ultimate) I would like to use Qt Creator and Qt Visual Studio add in, both LGPL versions.
There are minGW and VS2008 versions of Qt frameworks on the Nokia websites, I did not find VS 2010 version.
So I have installed Qt 2010.05 SDK and in the VS 2010 Command prompt the following steps have been performed:
configure -static
nmake sub-src
I checked Qt Creator and it successfully runs. After the translation has been finished I installed VS 2010 add I tried to add new Qt version int the path
C:\Qt\2010.05\qt
But the following error message has been appeared:
Qt in the given path was built using minGW
It do not understand why because the translation has been performed for the VS2010.
Where is the error? How to install it correctly?
I found out from a German Qt forum that, VS add-in looks for libqtmain.a and libqtmaind.a files to determine if it is built with MinGW. Guess what? Qt ships with those files.
Delete them, and you will be fine.
FWIW, The Vs2008 version works fine with VS2010. I didn't need to build it or anything. You can install that and then just run the latest version of the VS plug-in installer and you should see the Qt menu options in VS2010.
AFAIR your command line is incomplete: I remember one had to specify the build platform. It could be that it's using mingw to build Qt since you didn't specify the VS version in the parameters. The following post might be of interest to you: Building Qt 4.5 with Visual C++ 2010
