Hello, 8.8 The eval Function has an example of using eval, foreach, ... and I am planning on using something a bit like that myself. The example provided has a two problems and I have a fixed version (tested on GNU Make 3.80 on solaris).
You might like to incorporate this fixed version in the manual? Or something like it. I know examples are just that and it's a bit pendantic to get them fully working but you might find this useful. Attached here please find a tgz of dummy c files and working Makefile. (my "working" makefile does @echo $(CC) etc; touch FileThatWouldBeCreated so it can be tested in dummy mode)Two lines had problems: (see original Makefile and modified one (as in tgz) below)
$(1): $$($(1)_OBJ) $$($(1)_LIBS:%=-l%)
and
$(LINK.o) $^ $(LDLIBS) -o $@
The first makes e.g. -lpriv and -lprotocol dependancies of server or
client.
Probably not what is intended. So it could simply be replaced with: $(1): $$($(1)_OBJ) Usually making the build dependant on the lib files is not done unless the lib files are also built in the same makefile. But this is what I am doing so a more interesting replacement would be: $(1): $$($(1)_OBJS) $$($(1)_LIBS:%=lib%.a) On the second line the $(LINK.o) looks quite dodgy. Maybe it could be defined but I replaced it with $(CC) -r Okay well, small change, lots of guff from me, Not too sure where the gnu make manual source is so apologies for not submitting in patch format :-7 In the hopes it is slightly useful to someone .... James. Gnu make manual referred to as is on web here: http://www.gnu.org/software/make/manual/html_chapter/make_8.html#SEC85 Original example: PROGRAMS = server client server_OBJS = server.o server_priv.o server_access.o server_LIBS = priv protocol client_OBJS = client.o client_api.o client_mem.o client_LIBS = protocol # Everything after this is generic .PHONY: all all: $(PROGRAMS) define PROGRAM_template $(1): $$($(1)_OBJ) $$($(1)_LIBS:%=-l%) ALL_OBJS += $$($(1)_OBJS) endef $(foreach prog,$(PROGRAMS),$(eval $(call PROGRAM_template,$(prog)))) $(PROGRAMS): $(LINK.o) $^ $(LDLIBS) -o $@ clean: rm -f $(ALL_OBJS) $(PROGRAMS) Modified "fixed" (but dummy link/lib) version: CC = gcc PROGRAMS = server client server_OBJS = server.o server_priv.o server_access.o server_LIBS = priv protocol client_OBJS = client.o client_api.o client_mem.o client_LIBS = protocol # Everything after this is generic .PHONY: all all: $(PROGRAMS) define PROGRAM_template $(1): $$($(1)_OBJS) $$($(1)_LIBS:%=lib%.a) ALL_LIB_FLAGS += $$($(1)_LIBS:%=-l%) ALL_OBJS += $$($(1)_OBJS) endef $(foreach prog,$(PROGRAMS),$(eval $(call PROGRAM_template,$(prog)))) # dummy link and library creation $(PROGRAMS): @echo $(CC) -r $^ $(LDLIBS) -o $@ libpriv.a: touch libpriv.a libprotocol.a: touch libprotocol.a clean: rm -f $(ALL_OBJS) $(PROGRAMS) libpriv.a libprotocol.a
