Project ERROR: Unknown module(s) in QT: gui core

[er0d]

Hi,

I just installed Qt Creator on a Windows 7, but I can't compile anything. It is the 'community' version. Here is the version details:
Qt Creator 3.4.0 (opensource)
Based on Qt 5.4.1 (MSVC 2013, 32 bit)
Built on Apr 22 2015 04:15:14
From revision 6302a28c97

I try to compile the examples given with the IDE, but I always got the followin error:
Project ERROR: Unknown module(s) in QT: gui core

I also noticed that the Qt headers are not found by Qt Creator.

But Qt Creator seems to be correctly configured (using msvc 2013 as default compiler).
. In "options -> build & run -> kits", the "Desktop Qt 5.4.1 MSVC 64bits" is set as "default".
. In "options -> build & run -> compilers", all the different versions of MSVC installed on this computer are corretly listed. (I got 3 different versions)

Any idea?

Hi and welcome to devnet

Windows users are often using spaces in the path for Qt installation. Some tools not like spaces in the path. If you have "C:/Qt/..." and spaces afterwards, you better reinstall.

Hi koahnig,

you were right. I installed Qt in the "Program File" folder, and that was the source of my troubles.
I reinstalled it in a "blank space free" location, and now everything works perfectly.

Thank you.
