What is Qt? And where do I get it?

Question

How do I install Qt-devel (4.5)? Where do I get it?

I need to compile cpp files into an executable. I have no idea how this works.

Answer 1

Qt is a cross-platform application and UI framework. It includes a cross-platform class library, integrated development tools and a cross-platform IDE. Using Qt, you can write web-enabled applications once and deploy them across many desktop and embedded operating systems without rewriting the source code.

Answer 2

As the answers above say, it's a cross platform C++ framework.

When you say qt-devel, it sounds like a specific package. Your Linux comes as a series of packages that you can then install with a package manager. What distribution (e.g. Fedora, Ubuntu) are you using? This is a common, core package. You should be able to use the software update tool for your specific Linux to get this package.

From Wikipedia:

Qt is a cross-platform application development framework widely used for the development of GUI programs (in which case it is known as a widget toolkit), and also used for developing non-GUI programs such as console tools and servers.

Qt is most notably used in Google Earth, KDE, Opera (before 10.60 version), OPIE, Skype, MO-Call, VLC media player and VirtualBox. It is produced by Nokia's Qt Development Frameworks division, which came into being after Nokia's acquisition of the Norwegian company Trolltech, the original producer of Qt, on June 17, 2008.
