Follow-up Comment #15, bug #30381 (project make): I support this feature.
I just tried to write a makefile that implicitly generates output files from XML control files, that contain references to other files in the XML. What I wanted was this: define futurebases $(shell xmllint --xpath "print(//futurebase/@filename)" $(1)) endef .SECONDEXPANSION: %.htb: %.xml $$(call futurebases, %.xml) $(HOFFMAN) -g $< It doesn't work. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?30381> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
