0) Here is the SINGS source code set: http://web.mit.edu/drela/Public/UE/sings.tar.gz But this won't do you any good without a decent Fortran compiler. Alternatively, you can download the executable and associated stuff as follows... 1) This is the SINGS Linux executable: http://web.mit.edu/drela/Public/UE/sings/bin/sings (0.7 MB) Download it to some convenient location on your system, e.g. to /usr/users/whatever/bin/ 2) You will also need a few supporting libraries and sockets in the following directory tar image: http://web.mit.edu/drela/Public/UE/ifclib.tar.gz Download the above tar file to some convenient location on your system, e.g. to /usr/users/whatever/ifclib.tar.gz and unpack it: % tar zxvf ifclib.tar.gz This will create the directory /usr/users/whatever/ifclib/ with the libraries needed to run SINGS. 3) Append the above directories to your executable path and your loader path: % setenv PATH /usr/users/whatever/bin:$PATH % setenv LD_LIBRARY_PATH /usr/users/whatever/ifclib:$LD_LIBRARY_PATH I also suggest adding the above commands to your .cshrc file, so you don't have to type them everytime you log on. 4) You should now be able to run SINGS: % sings See the sample session file for hints and sample commands: http://web.mit.edu/drela/Public/UE/sings/session1.txt
