I've just installed Qt Creator from the Ubuntu Software Center.

When I try to open any project other than a Qt Quick project I get following error message:

No valid qt versions found.
Please add a qt version in Tools/Options or via the maintenance tool of the SDK.

In Tools → Options → Qt4, qmake-qt4 was added to the list automatically.

This is what my Qt4 options menu looks like.

qt-creator options menu

Here is the output of dpkg --get-selection | grep qt.

What am I missing to get Qt Creator to let me open Qt C++ projects?

  • Add the name of the packages that you have installed check if you have qt-maker, designer, creator. – Bruno Pereira Dec 7 '11 at 19:15
  • I have designer, qtcreator and qmake-qt4. – Octavian A. Damiean Dec 7 '11 at 19:21
  • Please provide the output of dpkg --get-selections | grep qt. – Andrejs Cainikovs Dec 7 '11 at 20:26
  • You should also check for libqt4-dev. – Nathan Osman Dec 7 '11 at 20:41

The problem wasn't the missing Qt version but the missing tool chain.

In Tools → Options → Tool Chains add GCC and set your gcc path as the Compiler path.

I thought the qtCreator package would install g++, make, etc., but it doesn't. Install build-essential to solve it :).

As to me, it looks perfectly fine. My Qt versions tab in options dialog looks identically.
The only thing that comes into my mind, is that Qt version is saved per-project, which means that you need to change Build Settings in Projects tab by explicitly selecting Default Qt Version.

  • Don't judge hard, I might be wrong :) – Andrejs Cainikovs Dec 7 '11 at 21:16
  • Thanks for your help. I've posted an answer with the solution. – Octavian A. Damiean Dec 7 '11 at 21:56
  • Hmm.. Why the hell you don't have gcc in your PATH? :) – Andrejs Cainikovs Dec 8 '11 at 12:35
  • Well I don't know why it couldn't find it since /usr/bin is definitely in my PATH and gcc is in there. – Octavian A. Damiean Dec 8 '11 at 13:08
