The 6.001 system has two parts:
- One part is the Scheme system itself. There are two executables installed in /usr/local/bin, and several data files installed in /usr/local/lib/mit-scheme. The system requires about 30 Megabytes of disk space. Before downloading the tar file, be sure you have enough free space on /usr/local. If you do not have enough space on /usr/local you can use symbolic links to other parts of the file system -- but you will be on your own to make sure that it all works (the lab TAs may be able to help).
- The other part is for problem sets. This can be placed anywhere you like. Over the course of the semester you should assume that it will grow to be about 5 Megabytes (maybe). There will be two subdirectories: psets (where you will install the problem sets as they are distributed) and work (where you will write your solutions).
- Download the Scheme system (TAR.GZ - 11.5 MB) - a TAR file, compressed with gzip - into a temporary directory of your choice. Let's assume that you put the file into /tmp/gnulinux-6001.tar.gz
- Be sure you are logged in with root privileges. If your system does not have a directory /usr/local, you will need to create one. Then execute the command line:
cd /usr/local; tar -xvzf /tmp/gnulinux-6001.tar.gz
- As part of your normal initialization (perhaps in your .login or .cshrc file) set an environment variable named MITSCHEME_6001_DIRECTORY to the directory in which you plan to store the problem sets (be sure the directory exists and has two subdirectories, named psets and work).
- The command line to start Scheme for use in 6.001 is
scheme -large -band 6001.com -edit
(you might want to make an alias for that command line -- you are likely to be typing it often!)
- If everything seems to work you can now remove the tar file:
Note: We have tested this Scheme system under RedHat Linux® 5.2, 6.2, and 7.0. Other versions of Linux® may need additional libraries to run this system. Ask for help if you run into problems.
