Simple GUI application crashes in Qt 5 - c++

After I downloaded and installed Qt 5. I opened Qt creator 2.6.1 and created a new simple GUI application. But when I try to run it, I get the following error:
C:\Qt\Qt5.0.0\5.0.0\msvc2010\include\QtCore\qglobal.h:46: error: C1083: Cannot open include file: ‘stddef.h’: No such file or directory
What is the problem and how can I solve it ?

You need to install the Windows platform SDK.
By the way: you used the wrong term (I assume). You application didn't crash it refuses to compile.

Hope this may help (a similar issue discussed here):

Getting Juce to Work (Windows)

I downloaded Juce and VisualStudio2017 because through researches it seemed that Juce was a good way to create a GUI app dealing with midi files.
My problem is i can't even get to use the first examples of GUI !
I get this type of error, for multiple different files :
[...]\juce\modules\juce_core\native/juce_BasicNativeHeaders.h(135): fatal error C1083: Cannot open include file: 'wininet.h': No such file or directory (compiling source file ....\JuceLibraryCode\include_juce_audio_formats.cpp).
Can anyone help me ?
Looking for this wininet.h file into google doesn't appear to give me any help :/
It seems that Windows 10 SDK JUCE was targeting by default was broken - multiple files, like wininet.h mentioned by you are missing there.
There are a few ways you can fix it:
1) You can get the latest JUCE develop where it is fixed, in particular it was fixed here
2) You can instruct Projucer to use the fixed SDK version by changing Windows Target Platform to 10.0.16299.0 (make sure you have the latest version of Visual Studio 2017 and that you have downloaded the Windows 10 SDK version 10.0.16299.0) as shown...
...here
3) You can wait for the new official JUCE release where the fix will be included (i.e. available on master).
Sorry for late response, usually the quickest way to raise any issues is via visiting forum.juce.com

error: C1083: Cannot open include file: 'ui_MainWindow.h': No such file or directory, Qt Creator

I'm trying to get a project that I downloaded from Github (https://github.com/Y-Vladimir/SmartDeblur) working in Qt Creator 3.4.1. However, when I build the project I get the two errors below.
I literally just installed Qt today, but from what I can gather those two ui files should be automatically generated when I compile. I think it might have something to do with the fact that I'm using an old version of Qt (4.8, the same version the Github project uses). I found this answer that seems related, but I couldn't get it working.
Can someone help me figure this issue out? Thanks

Qt Libraries are not included

I checked if the question exists but it doesn't seem to help me. I'm clearly new to Qt, i installed Qt Creator 5.4 in my Windows 7 Ultimate. I installed everything Qt 5.4 provides and also installed MinGW 4.9.1. The problem is when i open a console application project it immediately gives these errors. I tried different projects and error is the same.
Project ERROR: Unknown module(s) in QT: core
I tried to check intellisense for include and it didn't show ANY library to me.
When i hover to include it gives : QCoreApplication: No such file or directory
I highly doubt Qt can't find it's own libraries. How can i show it to QtCreator ?
Additional info : Run button and everything related to run is disabled.
Any help will be appreciated, thanks :)
Maybe your project's path contains non ASCII characters.
Try a new project somewhere like C:\MyApp

I cannot build and run a simple Qt 5 application,

I downloaded and installed Qt 5 on Windows 7.
I opened QtCreator 2.6.1 and created a new simple GUI application.
When I try to run it, it says:
“C:\Qt\Qt5.0.0\5.0.0\msvc2010\include\QtCore\qglobal.h:46: error:
C1083: Cannot open include file: ‘stddef.h’: No such file or
directory”
What is the problem and how do I solve it?
My compiler is: MSVC2010 32 bit
A google search yielded the following:

This thread notes that this error happens when you don't have the Microsoft Platform SDK installed and you are using Visual Studio. That would make sense considering that stddef.h is one of the standard headers (usually its included using <cstddef>, but looking at the source for qtcore/global.h it would seem that it is indeed included as <stddef.h>). So, try installing the platform SDK if it isn't already there.
If you already do have the sdk, perhaps it isn't configured properly. This answer says you need to follow the instructions given by microsoft here to do command line builds properly. I think Qt Creator probably executes the compiler from the command line, so that may help.
If that still doesn't work, try installing the MinGW compiler and using that. I have seen a few references saying that its easier to compile for Qt under windows using MinGW.

Basic Qt app crashes upon launch

When I launch a basic Qt app within Eclipse, it crashes with a ".exe has stopped working" error.
The context :
its the basic app obtained when creating a Qt GUI project (with a MainWindow), nothing was changed in it, haven't even added a button
PATH has all the necessary stuff (mingw, msys, qt)
project properties and eclipse paths should be ok too (c++, qt, mingw)
the .pro file is ok, no file missing
clean & rebuild, as well as relaunching eclipse doesn't resolve the problem
upon compilation there is no error, just an ignored "cannot lstat `ui_.h': No such file or directory". No relevant result found when searching around that.
if launched, stops with the afforementionned error. Details show its the app that crashed, with error code c0000005, offset 00002cb20. Search results tells me c0000005 is access violation, but where would that come from ? It's the basic app...
tried to launch with eclipse being in admin mode to prevent accesss violation, didn't help
if launched in debug mode, stops with error "Can't find a source file at ../mingw/main.c". I thought I forgot something when I installed mingw, so I did its setup again, but that did not create that file. No relevant search results here either.
my setup: eclipse classic x32 with c++ & php stuff, qt 4.8, win7 x64
I'm getting lost here. I already worked with Qt under Eclipse before (on winXP and vista), got my bunch of installing problems but this one is a first. Anybody went through this already ? Any leads on how to find where the access violation is happening ? Reading this question makes me think it's a Qt Eclipse Integration problem, but how can I circumvent that ?
Thanks for any leads !
Your project doesn't have a TARGET = set in the .pro file. This was probably caused by an Eclipse/Qt plugin wizard screw up, so just typing a new target may not work, other files may have to be renamed manually.
FWIW development on the Qt plugin for Eclipse was halted some time ago, building outside of Qt Creator is definitely one way of making life more difficult for yourself.
