To compile TPT++ you need to do the following:

1) Open your Terminal and type:

sudo apt-get install build-essential libsdl1.2-dev libbz2-dev zlib1g-dev liblua5.1.0-dev fftw3-dev scons (64 bit systems use lib64bz2-dev, also you might have some of these packages installed, so if you see "X is already newest version" just ignore it)

You MUST have Python installed and working in order for scons to work!

2) Get the TPT++ source code from Simon's github (I will not cover how to use git in this tutorial, refer to the old compiling tutorial for TPT -- [1])

3) Navigate to your folder containing the TPT++ source code and type:

scons --lin --release (You might add --32bit or --64bit depending on if your machine is 32/64 bit)

You can also use --sse3 if your computer is under 6 years old.

4) Once scons has finished compiling (it will say "Done building targets" in the terminal), you will need to navigate to the "build/" folder, you can do this by typing cd build/ in the Terminal.

5) Run TPT++ by typing ./powder-legacy
