How to set up MIT Scheme for 6.001 in Ubuntu 8.10

Question

I play to self-study 6.001 with the video lectures and lecture handouts. However, I have some problems setting up MIT Scheme in Ubuntu (intrepid).

I used package management and installed MIT-Scheme, but it's obviously the wrong version to use. It should be 7.5.1 instead of 7.7.90

I followed the instructions from this website (http://ocw.mit.edu/OcwWeb/Electrical-Engineering-and-Computer-Science/6-001Spring-2005/Tools/detail/linuxinstall.htm)

So far, I've downloaded the tar file, and extracted to /usr/local. I have no idea what step 3 means.

Then I entered command

scheme -large -band 6001.com -edit

and the error is

Not enough memory for this configuration. I tried to run under sudo mode, and this time the error is different Unable to allocate process table.

Inconsistency detected

I have close to 1GB of free memory, with ample HDD space. What should I do to successfully set this up?

Answer 1

Step 3 means that you should type export MITSCHEME_6001_DIRECTORY=${your_problems_path}. If you don't want to type it every time you launch Scheme, you should put it as a string in your ~/.bash_profile file(in case you use bash)

About the problem itself, Google instantly suggests a solution: sudo sysctl -w vm.mmap_min_addr=0(taken from http://ubuntuforums.org/showthread.php?p=4868292)

Instead of the package manager, you may also want to compile the portable C sources for Unix. I am using it happily.
