Setting Up your Environment

A Walkthrough

Updated: April 20, 2014

Files. All of the programs and files mentioned for the last part of the course can be found in the /courses/cs3410 directory in the CSUG (or in standard locations on most linux machines for things like xxd and cat). You should copy these files to your VM (for consistency sake, your home folder). You should also vary the server as to evenly distribute the load. Try your netid mod 15 for example. Specifically, in your VM terminal type:

  $ cd
  $ rsync -avzr netid@csug02.csuglab.cornell.edu:/courses/cs3410/lab4/* ./lab4
  $ rsync -avzr netid@csug02.csuglab.cornell.edu:/courses/cs3410/mipsel-linux/* ./mipsel-linux
    

$PATH. Now add these files to your PATH so that your shell knows where to find all of the mipsel-linux tools.

• If you are using the tcsh shell:

      $ setenv PATH ${PATH}:/home/[user]/mipsel-linux/bin
        

  To avoid having to re-set your PATH every time you log in to your VM:

      $ cd
      $ echo 'setenv PATH ${PATH}:/home/[user]/mipsel-linux/bin' >> .cshrc
        

• If you are using the bash shell (the VM uses this by default):

      $ export PATH=${PATH}:/home/[user]/mipsel-linux/bin
        

  To avoid having to re-set your PATH every time you log in to your VM:

      $ cd
      $ echo 'export PATH=${PATH}:/home/[user]/mipsel-linux/bin' >> .bashrc
        

Troubleshooting

• If you encounter /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory, execute

  	$ sudo yum install glibc.i686
