Chapter 7: Building the Darwin Kernel

Updating sources

To bring a module into sync with the latest changes to the repository, use

the update command:

cvs -z3 update -P -d modulename

The -d option tells CVS to pick up any directories that were recently added,

and -P tells CVS to prune any directories that were recently removed.

If you use modulename with the update command, you need to

be in the same directory where you originally issued the

checkout command. This will be the parent directory of the

module’s top-level source directory. If you don’t specify a

modulename, CVS will update only the files in and below your

current working directory.

Here is an example session in which a module is checked out, its contents

perused, and its source updated to the latest version:

% cvs checkout testmodule

cvs checkout: Updating testmodule

U testmodule/Makefile

U testmodule/bar.c

U testmodule/foo.c

% cd testmodule/

% ls -l

total 24

% cvs update -P -d

% ls -l bar.c

Getting the Right Version

The only version of Darwin that should work with your copy of Mac OS X is

the same one that Apple used. Your mileage may vary if you try to use an

older or newer version. So, before you try anything like that, get the correct

version and use that as a dry run to verify that you can build and install a

working kernel.
