The Problem
I cannot stress this enough but I have looked as far as I can over the internet for a solution and either they didn't have a solution or all they did was add a support ticket. The problem is that after creating a python qt quick application I try opening the QML file but when I go to the design tab it give me this error:
Code
The Designer is very finicky and can crash for various reasons. I've had success seeing the actual errors causing this dialog by launching Creator from the command line with debugging enabled:
QT_LOGGING_RULES="qtc.nodeinstances.init.debug=true" "/Applications/QtCommercial/Qt Creator.app/Contents/MacOS/Qt Creator"
That's specific to macOS but the like approach should work on any OS.
Look for error messages related to "Puppet". That's the name of the subprocess that actually renders the QML for Designer.
You can also go to Preferences -> Qt Quick -> QML Emulation Layer and try the opposite of the current setting and see if it works any better.
The solution that works for me is as follows:
OS: windows 10
Go to Tools >> Options >> Qt Quick >> (tab) Qt Designer
In the "Use fallback QML emulation layer", you see the placeholder path there. Switch it to C:\Qt\Tools\QtDesignStudio\bin or use browse if you have a different install location for Qt such that path\to\QtDesignStudio\bin
Boy do I have a FIX for you guys. I had been screwing around with this same issue to no avail, until I came across an error that wouldn't let me download qt3d (something) and I know that was part of the installation choices so I decided to uninstall everything. A thing to note when uninstalling: the Maintenance Tool doesn't uninstall everything. There were still Qt files located in C:\Users\user\AppData\Roaming I needed to delete those. Also, I needed to go into the Registry Run >>> Regedit >>>> Edit >>> Find >>> then search for Qt and that brought up all of the QT keys that still remained. I just deleted them one by one. For the Reinstall I practically installed everything (within reason) here's the list of my installation selections. Happy Hunting Fellow Qt'errr's!

Graphic drivers were the issue in my case. Try updating or changing them.
Maybe that your Direct3D driver seems to have issues with Qt.
The error can be avoided by defining:QT_OPENGL=software in the Windows environment.
Assuming the root cause is the display driver of your computer.

I am trying to install Qt4.8.7 for Windows 10 and I am having some issues with installing the corresponding compiler.
I got the Qt4.8.7 installer from this link: https://download.qt.io/archive/qt/4.8/4.8.7/ and I have tried working with the MSVC2010 and the mingw versions. For the MSVC2010 version, I followed this guide https://wiki.qt.io/How_to_setup_MSVC2010 (with a lot of dead links) and installed the compiler alongside the MSVC service pack 1 and Windows SDK 7.1. I have not been able to find an installer for Visual Studio 2010 or the VS service pack 1. Qt studio recognises the version of qt I have installed alongside the corresponding MSVC2010 x86 compiler but when I compile I get this error for a missing header: "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\intrin.h:26: error: C1083: Cannot open include file: 'ammintrin.h': No such file or directory".
For the mingw version, I have not been able to find the correct version "mingw482" and other versions I have tried do not seem to be compatible. I have tried mingw installer programs as well as using the QT online installer to try and find the correct version but I haven't had much luck when compiling.
Has anyone got qt4.8.7 running on windows recently? If so, could you please point me in the right direction for installing the correct compiler?
Many thanks.
Here a short description for getting it to work with Visual Studio 2008 and the newest Qt Creator 4.13.
You will need:
Visual Studio 2008 Express for the build tools, there are no standalone build tools as far as I'm aware
Qt 4.8.7 precompiled for VS2008 from this link to Qt archives at the time of writing this the version you need is called "qt-opensource-windows-x86-vs2008-4.8.7.exe"
Any Windows debugger cdb.exe
Steps (all absolute paths are standard installation paths):
Install VS2008
Install Qt 4.8.7
Open your Qt Creator go to Tools->Options...->Kits->Tab Compilers and search for "Microsoft Visual C++ Compiler 9.0", it probably won't be there so you will need to add it by hand by looking for the vcvarsall.bat of this compiler. You will find it in C:/Program Files(x86)/Microsoft Visual Studio 9.0/VC/vcvarsall.bat. Repeat for C, C++, x86 and x64. Press save
Open the Qt-Versions tab and look for Qt 4.8.7 Version. It will probably not be there again so add it by hand by selecting the qmake.exe from C:/Qt/4.8.7/bin/qmake.exe. Press save
Open the Kits tab and add a new kit. Select your Qt 4.8.7 version and the MS compilers for C and C++, your favorite debugger and input the Qt-makespec win32-msvc2008. Press save again
Now you should be able to compile your project from Qt Creator and Qt-colored-commandline. For integration of MSVC 9.0 into Visual Studio 2015 and newer you will also need to install Visual Studio 2012 Express. In that order:
VS2008
VS2012 (Here MS programmed in some magic so newer VS can see older build tools)
VS201x
It could work in any other order but don't rely on it. Also it could just flat out not work and you will waste a week of your life to fix it; but then it will work.
Haven't tested it but I could imagine the same workflow will work for VS2010.
Qt 5.11. Mac OS X.
I'm trying to write automatic build script for Jenkins. Target platform: Android armv7.
androiddeployqt says me that it cannot find ant in PATH.
Yes, I did not install Ant.
But, it works somehow with Qt Creator. Qt Creator can build APK. Why so? It uses the same androiddeployqt, doesn't?
Do I really need to install ant (while Qt Creator does not need it)?
Qt Creator uses undocumented --gradle option. Add it to your command.
I'm running Debian 7, 32 bits. I've downloaded Qt here: http://qt-project.org/downloads
I took the link "Qt Online Installer for Linux 32-bit (22 MB) ". I then installed Qt, it worked but when I want to build a project, I get this error:
Qt Creator needs a compiler set up to build. Connfigure a compiler in the kit options.
I searched but I can't find how to solve this issue...
First make sure that you have a C++ compiler installed on your system and than in Qt Creator you go to Tools->Options->Build & Run->Kits and make sure that the kit has a compiler selected.
So I thought upgrading Qt and Qt Creator was a good idea since I used an older version of both.
I re-installed everything as I should and realized that Qt 5 is only for VS2010 for Windows which I have never worked with since I have been sticking with minGW up to this point,
I then realized my problems that my project wouldn't compile and run so I tried to download the 4.8.4 version with minGW, but that complained that:
"The installer could not find a valid c:\MinGW32\include\w32api.h
(Only versions with W32API3.13 are supported)"
and further I did not get creator when I installed it either.
Any help that would either let me go back to 4.8.8 minGW or a simple straight forward way using Qt creator with VS2010 would be appreciated, thanks.
I think I solved parts of my own issue (at least enough to answer this problem).
1: Download and install latest minGW installer and add ';C:\MinGW\bin' to the system variable 'path'.
2: Download the Qt 4.8.4 and install it (Does not come with Qt Creator) and add'C:\Qt\4.8.4\bin' to the system variable 'path'.
3: Download the latest Qt Creator, launch it and go:
tools -> options -> build & run
From there choose the correct Qt version by pointing to the Qmake in the Bin folder (C:\Qt\4.8.4\bin in this case)
Also make sure it auto detects minGW compiler, if it does not show up I am not sure what to do.
4: If you are including a project from other Qt versions you might have to delete the users.pro file (not the .pro file) to get it to compile properly.
Last issue is that I do not have any debugger, but the program compiles in the /release folder (if you put CONFIG += release in the pro file) and I can run it by using the .exe.
Using MSVS 2010 as the compiler isn't too hard.
Download Visual Studio Express 2010.
Install it, and now you have MSVS 2010 compiler available.
The compiler should be located under C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin or somewhere similar at cl.exe.
Setting up the latest version of Qt built against MSVC 2010, with the latest Qt Creator isn't too bad, either. In Tools > Options > Build and Run > Kits, find your Qt qmake installation, and in Tools > Options > Build and Run > Compiler, find your compiler.
Now you can use the amazing Qt 5 instead of sticking in the past with 4.8 (even though Qt 4.8 is awesome and works really well, too).
Hope that helps.
I have some difficulties with QT, which I need for school for some GUI applications.
I have recently done these steps:
1) mingw-get-inst-20120426.exefrom SourceForge installed to C:\MinGW\ with default settings.
2) Qt libraries 4.8.4 for Windows (minGW 4.4, 317 MB) from QT Project installed to C:\Qt\ with default settings. Here an error occurs:
!!!There is a problem with your MinQW instalation
!!!g++ not found in c:\MinGW\bin\
!!!Do you still want to continue? Yes
I checked c:\MinGW\bin\ there is no such file
3) Qt Creator 2.6.0 for Windows (51 MB)also from QT installed to C:\Qt\gtcreator-2.6.0 with default settings
4) Run the QT IDE
5) Open project or create new project. Another error occurs here
!!!No valid kits fond.
Qt Creator uses the invalid kit Desktop to parse the project.
6) Open Options->Build & Run->Kits (But I don't know how should I set Kits and where to find them).
7) Can you also help me, how to set Qt version
(Options->Buid&Run->Qt Version)? Where do I find qmake.exe?
I also didn't find how to create GUI Application. There is no such option in New File or Project...
Thanks for help.
That is quite tricky ;)
Precompiled Qt (MinGW) is only win32 (not win64).
Precompiled Qt is compiled with MinGW-g++ 4.4 and won't work with other.
You have to download this one:
http://get.qt.nokia.com/misc/MinGW-gcc440_1.zip
//// Edit: With this version of MinGW, gdb won't work (it's not python-enabled). Although QtSDK is depracted (and you won't find it on qt-project.org), I highly recommend downloading this online installer and, during the selection of components mark only MinGW. It will come with folder named "pythongdb".

(You may need to register. It's free.)

Add "Compiler" by g++.exe
Add "Qt Version" by qmake.exe.
Add "Kit" with Compiler and Qt Version configured above. You can try to change debugger from CDB to GDB.
When you installed mingw, did you select the C++ compiler? It is not selected by default but you need it. Re-run the wizard and select that.
The kit is not valid because the C++ compiler cannot be found: try to install it first. If you still cannot setup this read the manual: http://doc-snapshot.qt-project.org/qtcreator-2.6/creator-targets.html. It is very complete.
qmake.exe is in *qt_directory*/bin/qmake.exe.
Try this out:
http://sourceforge.net/projects/mingw-w64/ (Since the mingw-w64 project on sourceforge.net is moving to mingw-w64.org i suggest to use mingw-w64.org)
It works for me.
