===== Porting FreeBSD =====

The following details are to be used for porting the %%FreeBSD%% kernel and/or base system to a new architecture (such as sparc64, arm, etc).

=== Building the tree in a non-standard location ===

**Note:** //These tips were explained to me by M. Warner Losh [[http://lists.freebsd.org/pipermail/freebsd-hackers/2006-July/017344.html|on the freebsd-hackers@ list]]//

<code>
setenv TARGET arm			# this may be iguana for you
setenv TARGET_ARCH arm
setenv MAKEOBJDIRPREFIX /home/imp/obj
cd p4/imp_arm
make buildworld
make buildenv				# from here on out is in a subshell
cd ../arm/src/sys/arm/conf
config KB920X
cd ../compile/KB920X
make depend && make
</code>
