'Qt 5.1.1 compiler setup on Ubuntu

First of all, I should point out that I've never used linux before.

I have a clean install of 64bit ubuntu, I downloaded Qt 5.1.1 for linux 64 bit from http://qt-project.org/downloads, ran the .run file, installed it and gcc which is included in that download, opened Qt Creator, made a new project and tried to compile it. It wont compile and I keep getting this error message

:-1: error: Qt Creator needs a compiler set up to build. Configure a compiler in the kit options.

I added a gcc compiler, but what do I need to put for the compiler path, platform codegen flags, platform linker flags and ABI?

You don't have to input the path of your compiler because gcc and g++ paths are available in the $PATH enovironment variable. So just use "gcc" and "g++" and that should work. Just make sure you restart Qt Creator after the installation of g++.

One more thing. You need a compiled version of Qt installed on your computer. So also install Qt libraries with

sudo apt-get install qt4-dev-tools

If you want to use the new version of the library you have to add it to $PATH. You can do this in the terminal with

export PATH=/path/to/Qt/qtbase:$PATH

And then run Qt Creator from the same terminal, in which you did the last command.

Good luck!

You will have to install the dependencies as well. I got it working when I followed the steps in the following link.
