[koahnig]

which Qt version have you installed?
from where did you download?

[haggag87]

5.0.1 from the official website

[koahnig]

When you have the precompiled build of qt 5.0.1 for msvc 2010 installed, you should have also Qt creator. Did you try to use Qt creator instead?

[haggag87]

I've opened Qt creator and couldn't find any example in the examples tab!

[koahnig]

you should be able to go to "File" > "Open File or Project" and navigate to the examples installed. Typically on the Qt installation folder. I have Qt 5 not installed, but I assume it should be there. Go to the folder of one of the examples you like to try, there you should find a file type "Qt Project File". Those are the project files.

QT, error MSB6006 : "cmd.exe" exited with code 3
I had this stupid error: I was working on a relatively fresh PC (Windows 7 Pro).
I got rid of this particular error by introducing a QTDIR environment variable (that didn’t exist before):
Press Windows START button
Press “Control Panel”
Press “System”
Press “Advanced System Settings”
On the [ADVANCED] tab – press button [Environment Variables] at the bottom
Under “System Variables”at the bottom – press [NEW]
Add QTDIR environment variable. In my case that value was “C:\Qt\5.9.1\msvc2017_64” (it has ‘bin’, ‘include’, ‘lib’ directories – the works!).
I saved this and RESTARTED my computer for better measure (Didn’t seem to “just wok” – at least not for me).
OK: now I was getting the following error:
C1083: Cannot open include file: 'stddef.h': No such file or directory
...OK what got me out of THIS was:
[Project] → Properties → Windows SDK version... - I change this from “8.1” to something stupid called “10.0.17134.0” (whatever the hell that means: to me this is all magic).
