3# Makefile for building PICOBSD kernels and running crunchgen
4#
5# Needs SRC pointing to the source tree,
6# MY_TREE ponting to my tree
7# BUILDDIR pointing to the build directory
8# PICO_OBJ pointing to the object directory
9# When building a kernel, also need ${name} from the environment
10# and CONFIG may indicate an alternate config program
11
12SRC?=/usr/src
13CONFIG?=config
14MODULES?=-DNO_MODULES	# do not build them as a default
15
16# caller will set MODULES to empty if modules are needed.
17# Indeed, it can be used to specify other Makefile options as well.
18
19# These 3 variables determine where the kernel is built.
20# If config were smart enough, we could place the config
21# file in some other place than ${SRC}/sys/i386/conf, but
22# at the moment (Oct.2001) this is not possible yet.
