Hi I have updated visual studio to 2015 version and I have Qt msvc2013. Qt says that no compilers can make code for this version of Qt, (Qt detected compilers from visual studio). How can I make it working without installing VS2013?
You cannot mix C++ compiled with different major versions of the Microsoft Visual C++ compilers. So you need to either get a version of Qt for Visual Studio 2015, or compile your own one.
At this time, there is not yet an official build of Qt for Visual Studio 2015 available (this is planned for Qt 5.5.1 5.6.0). If you want to try compiling yourself, https://wiki.qt.io/Building_Qt_5_from_Git is a comprehensive guide. You should try either the 5.5 branch (if you get the Qt sources from git), or the 5.5.0 source packages. You should be able to get help e.g. on the qt-interest mailing list.
Adding a new mkspec is pretty simple, just copy the win32-msvc2013 and rename it to win32-msvc2015, then modify and use that one.
Second thing to do is not try to link against 2013 built libraries. If 2015 follows the same pattern as the older one, mixing libraries from different VS version is not possible.
Last thing, before adding icu, OpenSSL and MySQL you rather try to build Qt with the default parameters.
Qt's current development version is 5.6.
It is in beta and there are prebuild binaries for msvc2015.

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
At the official Qt library site present only Qt add-in for Microsoft Visual Studio 2013 and 2015. And there are no one for MSVS 2017.
How to use Qt library with visual studio 2017 in this case?
You can get the add-in beta here, it should be mostly working. I mean if you want IDE integration. Otherwise it should build fine via the build tools command prompt (or however they call it now) via qmake project and then make.
As for building the Qt framework itself, it should probably work too, maybe with the exception of the QWebEngine stuff. It also seems that MSVC 2017 and 2015 are binary compatible, so it may be possible to use Qt binaries, built with MSVC 2015, therefore making it an option to avoid building Qt from source.
IIRC the incoming version 5.9 will offer MSVC 2017 prebuilt binaries.
I would like to install latest version of Qt (5.5) on Windows 7 for C/C++ application development, and have a few questions:
Can I use Microsoft "Visual Studio Community" edition (2015) as the compiler?
I assume I need to install Visual studio first and then Qt?
I am going to install Qt from here, after downloading and installation do I need to build Qt? Or it is ready to go?
Is there a tutorial that explains all the required steps in details. I have done Google search and found bits and pieces here and there not not a good complete step-by-step reference.
Thanks for the help.
You need the compiler, which is integrated in visual studio. I don't think you can get the newer ones without Visual Studio (From official sources). However, you can use Qt on windows without msvc. You can build with the minGw compiler - but I personally like msvc more.
Regarding VS2015: It won't work without extra configuration. Qt 5.5 supports msvc2013 only (the next release, 5.6, will support the msvc2015 compiler). But Visual Studio 2013 will work. The order of installation doesn't matter.
After you installed Qt, all you need to do is launch Qt-Creator and start coding ;) If you wan't to use Visual Studio instead, there is a Plugin on the bottom of the download page ("Other downloads"). Visual Studio 2015 isn't supported here too, but 2013 is.
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.

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).

Qt 5.0
Select the file according to your operating system from the list below to get the latest Qt 5.0 for your computer. The binary packages include Qt 5.0.2 libraries and Qt Creator 2.7.0
Qt 5.0.2 for Windows 32-bit (VS 2010, 485 MB)
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
