Why Ubuntu.Components 0.1 missing from QTCreator?

Solution 1:

I found out the solution at least for ubuntu 12.04. I had to go to the official site http://qt-project.org/downloads#qt-creator and download the latest Qt package which is Qt 5.0.0.

*Note: Ubuntu 12.04 doesn't include the latest Qt version, so you have to download it manually.

• Qt libraries 5.0.0 for Linux 64-bit (410 MB)
• Qt libraries 5.0.0 for Linux 32-bit (411 MB)

*Note: Before the installation i removed the previous version of QtCreator (2.5.0)

All you have to do in order to install Qt5 package is:

• chmod 755 qt-linux-opensource-5.0.0-x86_64-offline.run

Then just execute the package and run the installer with the default settings.

• ./qt-linux-opensource-5.0.0-x86_64-offline.run

• Now should exist /opt/qt5/imports/Ubuntu/Components path, with all the libraries!

After that i followed the instructions of the CurrencyConverter

*Note that line: import Ubuntu.Components 0.1 is still highlighted with a red line but the program runs normally by choosing Tools > External > Qt Quick > Preview (qmlviewer) (thanks to @David Planella)
