I suspect you'll need to ask questions like these on the automake
mailing lists. Cheers!
You're right of course! (though I'd done so already :)
I've ditched Automake and am instead using Autoconf and handcrafted
Makefile.in files instead, as I find they confer a much higher degree of
customization. Using your brilliant suggestion, I find setting up
projects is now effortless. The basic mechanics is as follows:
-- Makefile.in:
PROGRAMS = foo bar
foo_SOURCES = foo.c foobar.c
bar_SOURCES = bar.c foobar.c
include @srcdir@/build.mk
-- build.mk:
# construct list of objects per program
$(foreach I,$(PROGRAMS),$(eval $(I)_OBJECTS := $($(I)_SOURCES:%.cpp=%.o)))
# make each program dependent on required objects
$(foreach I,$(PROGRAMS),$(eval $(I): $($(I)_OBJECTS)))
$(PROGRAMS):
@echo "\033[1;32m[L] `basename $@`\033[0m"
@LINK_LOG="/tmp/`basename $@`.link.log"; \
[ -f $$LINK_LOG ] && rm $$LINK_LOG; \
echo $(CXX) $(CXX_FLAGS) -o $@ $(^) $(LD_FLAGS) 2>$$LINK_LOG ; \
$(CXX) $(CXX_FLAGS) -o $@ $(^) $(LD_FLAGS) 2>$$LINK_LOG ; \
EXIT_CODE=$$?; \
if [ ! $$? -eq 0 ]; then \
cat "$$LINK_LOG"; \
exit $$EXIT_CODE; \
fi;
%.o: $(srcdir)/%.c $(OUTPUT_PCH)
@echo "\033[0;32m[C] $<\033[0m"
@$(CC) $(C_FLAGS) -c $< -o $@

Thank you for the invaluable help, Paul!
