I have just installed the qt 5.7.0 and mingw 5.30 32bit on windows 10 64bit pc.
When Qtcreator run the first example which is given by the Qt creator, I always got an error that is ;
Starting C:\Qt\Examples\Qt-5.7\canvas3d\threejs\build-cellphone-Desktop_Qt_5_7_1_MinGW_32bit-Debug\debug\cellphone.exe...
The program has unexpectedly finished.
C:\Qt\Examples\Qt-5.7\canvas3d\threejs\build-cellphone-Desktop_Qt_5_7_1_MinGW_32bit-Debug\debug\cellphone.exe crashed.
There wasn't any error during compiling period
All settings are coming default and I didn't change anyting.
MinGW settings seem normal on the compilers setting.
How can I solve the issue?

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 wrote a program in Qt:
Qt Creator 3.5.1 (opensource)
based on Qt 5.5.1 (MSVC 2013, 32 bit)
Windows 8.1 64-bit
My program is running fine in Qt creator.But I want to execute it in other computers on all Windows without installing Qt. I copied all required .dll files next to the .exe file (Release build) with windeployqt.exe.
When I start the.exe, nothing happens.
No GUI showing up, no error that a .dll is missing. But I see my application in 'ProcessExplorer'.
This happen for even very simple program.
Here's a screenshot of my Dependency Walker screen for simple application:
I had exactly the same problem and as you, I had no error message or any output whatsoever. I solved the issue when I added the QML path to my deployment.
On this page, windeployqt, you will see the commmand:
windeployqt --qmldir < path-to-app-qml-files> < path-to-app-binary>
Here the command with the qml flag.
C:\Qt\5.10.1\mingw53_32\bin\windeployqt.exe --qmldir C:\My_project C:\My_project\build-My_project_MinGW_32bit-Debug
It seems you are using QML.
did you have a look at stdout / stderr? I have had that problem when my QML file was not loadable / path was incorrect.
Also settings environment variable QML_IMPORT_TRACE=1 helped me to spot these kind of problems.
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.
I installed BlackBerry NDK including IDE and downloaded the SDK. Now, I already set up Qt-Creator 2.8.1, 2.8.0, 2.6.2... In every version there is another problem with the build settings. The most appropriate try was with 2.6.2 and manually setting up the BB10 integration.
BB10 NDK Version: 10.1 for Target 10.1.0.4633 armv7le-v7
Creator is always started with bbnk-env.bat called before.
2.6.2:
Compiler set to GCC with custom-arm-linux-generic-elf-32bit as proposed by https://developer.blackberry.com/native/documentation/core/qt_porting_tools.html
(I do have a second compiler set to unix instead of linux)
QT-Version provided by Blackberry NDK, Qt 4.8.5 within %BBNDK%\host_10_1_0_238\win32\x86\usr\bin\qmake.exe.
Devices: BBZ10 is connected and accessible. QtCreator successfully connects and can use the debugToken.
Now the problem is within the Kits: Created a kit for BBZ10, having the bbZ10 Device, bbndk\target_10_1_0_4633\qnx6\armle-v7 as sysroot, compiler (set for linux), gdb to ntoarm-gdb.exe, QT-Version to configured 4.8.5. I can now try any mkspec it always gives me the error (translated from german)
No mkspec found for given QT Version
Für diese QT Version wurde keine mkspec gefunden
I think the mkspecs are set to compile to unix-target, while the 4.5qt supplied with the sdk requires to be linux target (where in reality target is QNX)
Somehow i can compile with this version, but first i am not sure if this creates a correct executable, even more i cannot deploy the executable, since QT-Creator does not create the bar-descriptor.xml file...
2.8.1:
Using the same setup as in 2.6 (after having 2.6 QT Version configured) i am able to get to the same error. Using the "new" configuration system under "BlackBerry" page in settings i cannot correctly set up NDK Path. Will always tell me (translated from german)
Following problems were encountered during BB10 configuration:
No QT-Version found
No GCC compiler found
No GDB Debugger for BB10 Comiler found
No GDB Debugger for BB10 Simulator found
Has anyone successfully configured bb10 ndk to use with qt-creator (2.6/2.8.1) and encountered similar trouble?
How can i solve this issue?
Solved:
After 24 hours trying, installing, reinstalling, editing, crying... I reinstalled complete NDK and QtCreator 2.8 and edited bbndk-env_10_1_0_4633.bat.
I removed every Variable from batch file and set it to corresponding values, e.g. replace every %BASE_DIR% with your acutal base-dir (i.e. D:\bbndk).
For conveniance usage i craeted another batchfile, calling the bbndk-env batch and starting qt-creator.
Set Compiler, Qt-Version, Kits in Creator-Settings as described in https://developer.blackberry.com/native/documentation/core/qt_porting_tools.html
Keep mkspecs line under Kits-tab empty
Thank You
i am new to Qt.
i am using Wnndows 8 with MinGW (gcc 4.7.2)
i have installed QtLibrary 4.8.4(the official site says Qt 4.84 should work with mingw 4.4)
After modified Windows environment variables, i installed Qt Creator 2.6 and setted the kit as well.
now i can compile the example program, but cannot run it, the error message I got is
Starting D:\usr\bin\Qt4\examples\opengl\2dpainting-build-Kit_3_14-Debug\debug\2dpainting.exe...
The program has unexpectedly finished.
D:\usr\bin\Qt4\examples\opengl\2dpainting-build-Kit_3_14-Debug\debug\2dpainting.exe exited with code -1073741502
i met the same problem with Qt 5.0.1 + MinGw 4.7.2 too.
i guess there is something wrong with "opengl", but don't know how to fix it.
please help.
Please try to place all required dlls into the directory where your exe is (see here).
Also make shure; if you are compilung in Debug you need eg. QtCored4.dll, but in release QtCore4.dll.
It all about x32 and x64 architectures,
If you compile cpp files in x64 mode and then link them with x32 qt the problem will occur.
try using the appropriate versions of windows and qt(both x32 or both x64)
