#Do a 'make setup', then a 'make', after copying this makefile into an empty
#directory

#This makefile 'Abort's when trying to build libfoobar.a(boggle/bar.o)
#under GNU Make version 3.54 on a Sun 3.

#The man page seems to indicate that this sort of thing (building libraries
#from objects in subdirectories) should be possible, but make -d shows something
#nasty happening while 'Trying implicit dependency `(boggle/s.bar.o)'.'

#Note that 'make boggle/bar.o' works fine

#A make bug, or am I not using this right ?

libfoobar.a:	lobfoobar.a(foo.o) libfoobar.a(boggle/bar.o)

boggle/%.o:	FORCE
		$(MAKE) -C boggle -f ../makefile $(notdir $@)

.PHONY:		FORCE

setup:		FORCE
		mkdir boggle
		touch foo.cc
		touch boggle/bar.cc
