Enclosed are my build notes for Tux Junior. The build platform is an Ubuntu 10.04 Virtual Box machine hosted on a MacBook Pro with 3D enabled. The same notes could probably be used to build the SuperTux platform game too.

# Get The Code
sudo apt-get install subversion
svn co https://supratux.svn.sourceforge.net/svnroot/supratux supratux

# SDL Stuff
sudo apt-get install libsdl-image1.2 libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-net1.2-dev libsdl-ttf2.0-dev

# Build Tools and Miscellaneous
sudo apt-get install build-essential libphysfs-dev automake jam libopenal-dev

# Own the build files if needed
sudo chown -R YOUR_USERNAME_HERE ~/supratux
sudo chgrp -R YOUR_USERNAME_HERE ~/supratux

# Compile Tux Junior
cd ~/supratux/trunk/tuxjunior/
chmod +x autogen.sh
./autogen.sh
jam

# After the build completes you should be able to run Tux Junior with:
./tuxjunior

# Building the Mono level editor
sudo apt-get install libgtk2.0-cil-dev gtk-sharp2 mono-devel ubuntu-mono
cd ~/supratux/trunk/tuxjunior/tux_level_editor/
make

# After building the editor run it like so:
mono --runtime=v4.0 tuxjunior-editor.exe
