Setting Up Qt Creator 1.3 with Qt SDK 4.5

I try to develop with Qt Creator 1.3 on Qt 4.5 built-in on Ubuntu, since Qt 4.6 is still building on my Core 2 Duo laptop.

Install package libqt4-dev using Synaptic to get the Qt 4.5 development library.

$ sudo aptitude install libqt4-dev

Launch Qt Creator. Now you can create a new project and launch it.

Qt Creator should detect your Qt4 installation properly.

You certainly want to enable the Debugging Helper.

1. Go to Tools -> Options -> Qt4 versions.
2. Under Debugging Helper, click Debugging Helper -> Rebuild.
3. The Debugging Helper icon will turn from red to green check mark.
