linux compilation instructions

gcc 4.0 or 4.1
OpenGL and GLUT
QT 4.2.3
Qt is a multi-platform GUI toolkit. Trolltech Qt is free and open source for Linux.
libQGLViewer 2.2.5-1
QGLViewer is a trackball-based 3D viewer including many useful features. It is packed as a QT widget and distributed as a free open source library.
lib3ds 1.2
The free open source library allowing to load and save 3DS files.
swig 1.3.31
SWIG is an interface compiler that connects programs written in C and C++ with scripting languages such as Perl, Python, Ruby, and Tcl. Freestyle uses it to generate the binding between its C++ API and the style scripting language Python.
Python 2.5
Python is an interpreted, interactive, object-oriented programming language. We chose it as our style scripting language.

1) You must set a FREESTYLE_DIR environment variable containing the freestyle directory location.
2) In $FREESTYLE_DIR/src edit the libconfig.pri. This file contains the locations of the various libraries headers and files. Modify the initial values facing the linux-g++ tags to match your own configuration.
3) Build Freestyle:
cd $FREESTYLE_DIR/src qmake make This will build Freestyle.exe as well as all its libraries in the $FREESTYLE_DIR\build\linux-g++\release or debug directory depending on your configuration. Only the swig library remains to build as it is currently not integrated in the QT process.
4) Build the Python API:
cd $FREESTYLE_DIR/src/swig make -f Makefile.linux make -f Makefile.linux install This step builds _Freestyle.so and Freestyle.py, i.e. the python API for style description, in the $FREESTYLE_DIR/build/linux-g++/release/python directory (or debug/python).
5) Run Freestyle: set LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./lib cd $FREESTYLE_DIR/build/linux-g++/release/ ./Freestyle Open the 'Windows' > 'Options Window', select the 'Directories tab' and add to the 'Python path' the location of the directory where the library of the previous was built (e.g. $FREESTYLE_DIR/build/linux-g++/release/python). Save and close the dialog window (you might need to reset the Python Interpreter through 'Tools' > 'Reset Interpreter').
7) Write great style modules and generate beautiful images. (Start perhaps by the tutorial).
