I wrote some blog posts about eval and other metaprogramming techniques in make that you might find interesting: http://make.mad-scientist.net/category/metaprogramming/ But, note that these don't have any relationship to make's jobserver and how many parallel jobs it will run. > > NPROC:=$(shell grep "processor" /proc/cpuinfo | cut -b12- ) > > # this returns "0 1 2 3" etc > > > > # Then you might use eval to generate rules dynamically: > > > > $(foreach N,$(NPROC),$(eval > > # YOUR DYNAMIC RULE > > MYTARGET_$(N): > > <TAB>mytool --dosomething -o$@ > > ) > > ) I guess I don't really see what the purpose of this is. If you have 2 CPUs you get targets MYTARGET_0 and MYTARGET_1. If you have 4 CPUs you get targets MYTARGET_0, MYTARGET_1, MYTARGET_2, MYTARGET_3.
