Exopc Exokernel Distribution

Exopc is stable enough to do libos and application development but there are still many bugs and features that have not yet been implemented. Do not expect to compile everything and replace your current system with XOK/ExOS. However, things are progressing rapidly and hopefully with making the sources public the 'net world at large can help speed development. Any additions or bug fixes are greatly welcomed and will be considered for incorporation into the main source tree.

Here's the  license  the sources are released under--please read this before downloading the distribution.

If you want up-to-the-hour source tree releases, there is a read-only anonymous CVS server. Please note that in June, 1998, long after the exokernel was a working system, the exokernel CVS repository was discarded, and the latest sources imported into the current repository. Thus, CVS does not accurately reflect who developed which piece of code. In particular, several of the original developers who made substantial contributions do not show up at all in the CVS history.

To check out the base exopc distribution is as easy as 1,2, 3:

[2]$ cvs login (just hit return at the password prompt)

[3]$ cvs -z1 checkout exopc (or any sub-modules, e.g. exopc/sys)

Use the -z1 to -z9 options to minimize network bandwidth. After you have performed the code checkout, you can use:

To keep your repository up to date. Note that cvs login creates a dot-file in your home directory -- $HOME/.cvspass. Also, if you do choose to use CVS then adding the following ~/.cvsrc file may help:

add -ko
checkout -ko
diff -ko
export -ko
rdiff -ko
update -ko

You can also browse the CVS repository via CVSWeb

If CVS really doesn't work for you, an aging snapshot is available at exopc-06-22-2000.tar.gz . This is 53 MB and may take some time to download. If you cannot get it all in one piece due to a poor connection, consider the curl program which knows how to do byte range retrievals.

Periodically a particularly stable version of the source tree is marked. The following string can be used with the CVS "-D" flag to update your sources to this version: 11/19/98 07:00:00 EST

Finally, several exopc mailing lists exist:

• exopc-announce@amsterdam.lcs.mit.edu is a low-volume list where messages about major events relating to the exopc distribution are announced
• exopc-discuss@amsterdam.lcs.mit.edu is a place to talk about issues involved in actively using or developing XOK/ExOS
• exopc-request@amsterdam.lcs.mit.edu  is a human read list that goes to the current maintainers of the exopc distribution. Send any questions, complaints, bug reports, or other comments to this list as well as requests to join the above two lists.
