# TOMOYO Linux kernel compilation

Last modified: $Date: 2011-11-20 09:56:56 +0900 (Sun, 20 Nov 2011) $

To compile kernel, the following packages are needed.

- gcc
- make
- ncurses

Run "make menuconfig" and choose the following options in "File systems" section.

- [*] SAKURA (Domain-Free Mandatory Access Control) support
- [*] TOMOYO (Domain-Based Mandatory Access Control) support
- (2048) Default maximal count for learning mode
- (/sbin/modprobe /sbin/hotplug) Built-in domain initializer programs
- [*] Auditing interface support
- (1024) Default maximal count for grant log
- (1024) Default maximal count for reject log
- <m> SYAORAN (Tamper-Proof Device Filesystem) support

The 2.6 kernels have a compilation option named CONFIG_DEBUG_INFO. If this option is enabled, the compiled code's size becomes about 10 times larger. Enabling this option consumes about 1 GB of extra disk space for /usr/src/ directory and about 300 MB of extra disk space for /lib/modules/ directory.
To save disk space, disable the following option.
