Building and Installing the Kernel

127

First, find your Darwin version with the uname -v command. The output

you’re looking for is the xnu (Darwin kernel) version, shown in italic type:

% uname -v

Darwin Kernel Version 6.0: Sat Jul 27 13:18:52 PDT 2002;

root:xnu/xnu-344.obj~1/RELEASE_PPC

You need to translate that number into an Apple CVS tag, by replacing the

period (

.) with a dash (-) and prefixing the version with Apple-. So, the

Apple CVS tag for the xnu version previously shown would be

Apple-344.

This is the version you must supply with the -r flag. Now that you know the

CVS tag, you can check it out:

cvs -z3 checkout -r APPLE_CVS_TAG modulename

Where APPLE_CVS_TAG is the CVS tag you computed, and modulename is xnu.

For example:

% cvs -z3 checkout -r Apple-344

cvs server: Updating xnu

U xnu/APPLE_LICENSE

U xnu/Makefile

U xnu/PB.project

U xnu/README

The CVS tags are symbolic names associated with a snap-

shot of the source code in time. An easy way to browse the

available tags is through the Darwin CVSWeb archive, avail-

able at http://www.opensource.apple.com/tools/cvs/. You will

need to provide your registered username and password to

access the archive. You can also use CVSWeb to peruse the

archive and view the source code.

Building and Installing the Kernel

Now that you have downloaded the source from CVS, you can change to the

xnu directory and load some environment variables. If you’re using tcsh, you

can use the following commands:

% cd xnu

% source SETUP/setup.csh

If you’re using bash or zsh, you can use these commands:

$ cd xnu

$ . SETUP/setup.sh
