	  AppArmor is an effective and easy-to-use Linux application
	  security system. AppArmor proactively protects the operating
	  system and applications from external or internal threats,
	  even zero-day attacks, by enforcing good behavior and
	  preventing even unknown application flaws from being
	  exploited.

	  This package installs only the library.

package/libapparmor: new package The layout of the package is not amenable to building both the library and the utilities at once, so this package will only install the library. The other apparmor-related tools however will almost all want to always link with the static library (it's hard-coded in their Makefiles, like: AALIB = -Wl,-Bstatic -lapparmor -Wl,-Bdynamic -lpthread), so we also force the build of the static library. The kernel headers 3.16 at least are required, for CAP_AUDIT_READ. We need to force the C standard to gnu99, otherwise: - autoconf uses wchar_t in C99 test, so considers it to be missing on toolchains without wchar, but wchar is not otherwise needed for libapparmor; - c99 is not enough, otherwise the build fails with errors like: kernel.c:503:15: error: expected declaration specifiers or ‘...’ before ‘(’ token extern typeof((__change_hat)) __old_change_hat __attribute__((alias ("__change_hat"))); ^ Signed-off-by: Angelo Compagnucci <angelo@amarulasolutions.com> [yann.morin.1998@free.fr: strip down the patch to only build the lib] Signed-off-by: Yann E.
