How to build XNU:

1) Setup your environment:

Create and go to your sandbox directory </sandbox/my_xnu>

$ cd </sandbox/my_xnu>

Extract the xnu project from cvs:

$ cvs co -r <xnu-tag> xnu

where <xnu-tag> must be replaced by the matching xnu tag for
the xnu project level.

Go to the top directory in your XNU project.

$ cd </sandbox/my_xnu>/xnu

If you are using a sh-style shell, run the following command:
$ . SETUP/setup.sh

If you are using a csh-style shell, run the following command:
% source SETUP/setup.csh

This will define the following environmental variables:
SRCROOT, OBJROOT, DSTROOT, SYMROOT

2) Export the Component Header Files

From the top directory, run:

$ make exporthdrs

This exports the component header files in the $OBJROOT/EXPORT_HDRS
directory.

3) Build all the Components

From the top directory. run:

$ make all
1) Type: "make"

This builds all the components for all architectures defined in
ARCH_CONFIGS and for all kernel configurations defined in KERNEL_CONFIGS.
