For various annoying reasons, I've just reformatted my hard drive and freshly installed the latest Ubuntu Studio LTS. As soon as I'd restored my home directory, I set to work compiling SuperCollider.
The README_Linux.txt file covers most of what you need to know, but here's what I had to type to get going:
sudo apt-get install git cmake libsndfile1-dev libfftw3-dev build-essential libqt4-dev libqtwebkit-dev libasound2-dev libavahi-client-dev libicu-dev libreadline6-dev libxt-dev pkg-config subversion libcwiid1 libjack-jackd2-dev emacs cd ~/Documents git clone --recursive https://github.com/supercollider/supercollider.git cd supercollider mkdir build cd build cmake .. -DSUPERNOVA=OFF make
You have to disable supernova because it requires a newer version of gcc. If all that works, then you can install it:
sudo make install
I had something go wrong with my installed SC libs, but that's a side issue.
