based on the last couple of replies here (thanks muchly), here's the
solution i came up with:
=========================================
define gen-obj-names
$(addsuffix .o,$(sort $(shell grep -h "^\#ifdef L_" ${1} | sed -e "s/^\#ifdef
L_"//)))
endef
define multisrc-rule-template
$(call gen-obj-names,${1}) : ${1}
gcc -DL_$$(basename $$@) $$< -o $$@
endef
MULTISRCS := $(shell grep -l "^\#ifdef L_" $(wildcard *.c))
$(foreach src,${MULTISRCS},$(eval $(call multisrc-rule-template,${src})))
=========================================
the only problem, though, is that someone suggested that invoking a
"call" from within an "eval" is not guaranteed to work in make-3.80
and earlier versions.
is there anything about the above that could cause problems in older
versions of make? if there is, then it's not really a usable solution
for me. thanks.
