Installation Notes

To install Scam, perform the following steps (using scam-2.1a-i386.tgz as an example)...

  1. Make a directory named scam that hangs off your home directory and then move into that directory
        mkdir ~/scam
        cd ~/scam
    
  2. Retrieve the tarball:
            wget beastie.cs.ua.edu/scam/scam-2.1a-i386.tgz
    

    Mac users may need to use curl -O instead of wget.

  3. Extract the files in the tarball:
        tar xvzf scam-2.1a-i386.tgz
    
  4. copy the scam executable to a directory in your path:
        cp scam ~/bin                # if you have your own bin
    

    or you can put ~/scam in your path. If you don't know what a path is, then do this instead:

        sudo cp scam /usr/bin
    
  5. It's unlikely, but you may need to install the readline library. On a Debian system like Ubuntu, you would issue the following command:
        sudo apt-get install libreadline6
    

    Look to the interwebs for instructions on how to install readline on other systems.
