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.
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?
