If you run out of disk quota while compiling the 6.894 software, you may be able to place the object and library files in /tmp as follows:
% cd ~/6894-0.1 % make distclean % mkdir /tmp/${USER}-build % cd /tmp/${USER}-build % ~/6894-0.1/configure % makeNow your source is in ~/6894-0.1, but your object files and executables are in /tmp/${USER}-build. You can run multifinger by typing% /tmp/${USER}-build/multifinger/multifinger
