:-1: error: Qt Creator needs a compiler set up to build. Configure a compiler in the kit options.

Well, you're not providing the information necessary to be more specific. Without any information but the error message all we can do here is repeat that to you:-)

Which compilers do you have? (Tools>Options>Build & Run>Compilers) Which Qt version? (Tools>Options>Build & Run>Qt versions, check the details there after clicking on one version). Which kit do you want to use and how is that configured.

I'm also getting an error in Visual Studio 2012 Ultimate when trying to create a Qt app:
First when clicking the first next > button in the Project wizard: http://i.imgur.com/5cZDM.png and when clicking finish it just takes me back to a new project.

You have MSVC 2012 installed. It cannot produce code for your version of Qt 5, which requires MSVC 2010. Those two compilers are incompatible.

Install MSVC 2010, and (most of?) your troubles should disappear.

Do you mean that I need another IDE, I don't understand much about the programs I need and stuff. Can you send me a link where to download it?

JKSH

No need to download another IDE :)

Visual Studio is Microsoft's IDE, which includes the Visual C++ compiler. However, if you don't want the full IDE, you can just get the Windows SDK 7.1 (http://www.microsoft.com/en-us/download/details.aspx?id=8279 ), which also contains the Visual C++ 2010 compiler.

After that, read this to "link" your new compiler with your chosen version of the Qt library: http://doc-snapshot.qt-project.org/qtcreator-2.6/creator-targets.html

The following should already be done for you automatically, but just in case, here are the instructions:
http://doc-snapshot.qt-project.org/qtcreator-2.6/creator-tool-chains.html

If you are talking about the Visual Studio Add-in, then the answer is: That add-in is not for Qt Creator. It is for people who want to write Qt programs using the Visual Studio IDE.

Did you restart your computer after installing the SDK, and before compiling your program? Windows 7 (and earlier) requires a restart after registering new environment variables.

If that doesn't help, try http://stackoverflow.com/questions/8800361/cl-is-not-recognized-as-an-internal-or-external-command

I'm running Windows 8 64-bit, could you please explain it yourself on how I do it because I'm getting sick of the hundreds of Microsoft sucky help pages. I have literally tried every single thing, WxWidgets seems to be better for me.

JKSH

I just looked at your compilers+kits screenshot again, and realized that you're using Visual Studio 2010, not just Windows SDK 7.1.

If I remember correctly, you'll still need to install Windows SDK 7.1, AND upgrade Visual Studio 2010. However, the installation order is important, because of "a bug in Microsoft's patches":http://blogs.msdn.com/b/vcblog/archive/2011/03/31/10148110.aspx. The correct order is:

Install Visual Studio 2010 (which you've already done)

Install "Windows SDK 7.1":http://www.microsoft.com/en-us/download/details.aspx?id=8442

Install "Visual Studio 2010 SP1":http://www.microsoft.com/en-au/download/details.aspx?id=23691

Install "Visual C++ 2010 SP1 Compiler Update for the Windows SDK 7.1":http://www.microsoft.com/en-us/download/details.aspx?id=4422

Note: If you've already done step #3 without doing step #2, you should uninstall Visual Studio 2010 and start again.

JKSH

Actually, I just remembered that someone has kindly provided an unofficial MinGW-based build, inclusive of a compiler, which should work out-of-the-box.

If you want to avoid the hassle of fixing your MSVC 2010 installation, you can use this instead: http://lists.qt-project.org/pipermail/development/2012-December/008919.html

I am getting this error too. I am trying to learn Qt. I download this development environment thinking it contains everything I need, but am un able to compile.

I have a fresh Install of Windows 8 Pro, absolutly no other programming tools installed. I downloaded Qt 5 just a few days ago and installed. Started a Qt GUI wizard app, tried to compile and got the error that I have no compiler.

Correct me if I am wrong, but should not this Qt designer install a compiler that works with itself? And of not, should it not prompt the user there is not one installed and give a link to download, or maybe have Qt installer get it itself and install it?

utcenter

Uh... windows 8, someone even tested this piece of #$@&?

The current offline installer DOES NOT COME with a compiler, and is build to work with Visual Studio 2010's compiler. You can get VS2010 express for free and install that.

... or wait a few more days for Qt 5.0.1 to come out, it will provide more pre-build binaries to work with different compilers, I suppose windows 8 will be a better match with VS2012, which I may say compiles and works very well with Qt with a few minor issues, but I am using windows 7. I even downgraded a new machine that came with 8 after spending some time with it and failing to get charmed...

changedsoul

I am forced to be on windows 8. I have tried and tried to downgrade to windows 7, but everytime I get through the install, it fails with not being able to configure on my hardware. I have begun to like windows 8 now that I can by pass that horrid start screen, and got my start menu back. Thank you for clarifying that this version doesnt come with a compiler. I will wait till one comes out that has one available.

You just need to make sure that your Qt Library was built using that compiler. Like utcenter said, the current Qt 5.0.0 package is for MSVC 2010; soon, Qt 5.0.1 packages will be released for MSVC 2010, MSVC 2012, and MinGW 4.7

There are 2 problems with providing a compiler:

It is illegal for us to provide MSVC or the Intel C++ Compiler
We used to provide MinGW (GCC for Windows), but people complained that:
** They already have a compiler, and didn't want to download a package that includes a compiler
** The flavour of MinGW that we provided was not the one they wanted

Anyway, Qt is a library. Libraries don't usually provide compilers (for example, GTK+, wxWidgets, and SDL don't provide compilers either)
