3 # Makefile for building PICOBSD kernels and running crunchgen
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
15 MODULES?=-DNO_MODULES # do not build them as a default
17 # caller will set MODULES to empty if modules are needed.
18 # Indeed, it can be used to specify other Makefile options as well.
20 # These 3 variables determine where the kernel is built.
21 # If config were smart enough, we could place the config
22 # file in some other place than ${SRC}/sys/i386/conf, but
23 # at the moment (Oct.2001) this is not possible yet.
