source: projectionDesigner/trunk/INSTALL @ 147

The linux version:
==================

* Introduction

First of all, create two directories! Qt-4.2.2 and usr in your home.
$HOME/Qt-4.2.2 will be your QTDIR.

Add the following lines to your .bashrc, and source it (or close and reopen your terminal)
    export QTDIR=~/Qt-4.2.2
    export PATH=${PATH}:${QTDIR}/bin
    export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${QTDIR}/lib:${HOME}/usr/lib

The Qt compilation will spent almost two hours, so this is the first thing to begin.

During the Qt compilation, you can install GLee and DevIL.


* The Qt library

Download (the OpenSource Version) from http://www.trolltech.com/developer/downloads/qt/x11 (careful: about 36Mo)

Uncompress, compile and install Qt in a local directory:
$ tar zxvf qt-x11-opensource-src-4.2.2.tar.gz
$ cd qt-x11-opensource-src-4.2.2
$ ./configure --prefix=$QTDIR # it takes 5mn.
(type 'yes' at the license question, if you agree)
$ make # Almost 2 hours but perhaps it is possible to remove some useless content (with the configure options).

There is nothing else to do during the Qt compilation, so you can go and read some Google News.

When Qt Compilation is over, then you can install it:
$ make install


* ProjDesigner

Uncompress, qmake and make it:
$ tar zxvf projection-designer-linux-rc1.tar.gz
$ qmake
$ make

And finally, to test, do not forget to declare that you want to link with glrc:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${PWD}/glrc
