4# For more information on building in tricky environments, please see
5# the list of possible environment variables described in
6# /usr/share/mk/bsd.README.
7#
8# Building recommendations:
9#
10# 1) If at all possible, put this source tree in /usr/src.  If /usr/src
11# must be a symbolic link, set BSDSRCDIR in the environment to point to
12# the real location.
13#
14# 2) It is also recommended that you compile with objects outside the
15# source tree. To do this, ensure /usr/obj exists or points to some
16# area of disk of sufficient size.  Then do "cd /usr/src; make obj".
17# This will make a symbolic link called "obj" in each directory, as
18# well as populate the /usr/obj properly with directories for the
19# objects.
20#
21# 3) It is strongly recommended that you build and install a new kernel
22# before rebuilding your system. Some of the new programs may use new
23# functionality or depend on API changes that your old kernel doesn't have.
24#
25# 4) If you are reasonably sure that things will compile OK, use the
26# "make build" target supplied here. Good luck.
27#
28# 5) If you want to setup a cross-build environment, there is a "cross-gcc"
29# target available which upon completion of: 
30#	make -f Makefile.cross TARGET=<target> cross-gcc"
31# (where <target> is one of the names in the /sys/arch directory) will produce
32# a set of compilation tools along with the includes in the /usr/cross/<target>
33# directory. The "cross-distrib" target will build cross-tools as well as
34# binaries for a given <target>.
