Hi Nicholas, Hi Nicholas,
I think this is probably the most straightforward solution. I'll give this a shot. Many thanks, Luke -----Original Message----- From: help-make-bounces+luke.goodsell=ogt....@gnu.org [mailto:help-make-bounces+luke.goodsell=ogt....@gnu.org] On Behalf Of Nicholas Clark Sent: 15 January 2015 18:18 To: help-make@gnu.org Subject: Re: Recursive implicit rules without explicit intermediates? How about using pattern substitutions? Something like: #-------------------------------------------------------------------# default: all #--------- Inputs ------------# INPUTS := in1.input in2.input in3.input SECOND_INPUTS := second_in1.input second_in2.input second_in3.input $(INPUTS) $(SECOND_INPUTS): touch $@ #------ Intermediates --------# INTERMEDIATES := $(patsubst %.input,%.intermediate,$(INPUTS)) %.intermediate: %.input cp $< $@ #--------- Outputs -----------# OUTPUTS := $(patsubst %.input,%.output,$(SECOND_INPUTS)) all: $(OUTPUTS) %.output: %.input $(INTERMEDIATES) cp $< $@ #---------- Misc ------------# clean: rm -f *.output *.intermediate distclean: rm -f *.input *.output *.intermediate .DELETE_ON_ERROR: .INTERMEDIATE: $(INTERMEDIATES) On Thu, Jan 15, 2015 at 4:15 AM, Luke Goodsell <luke.goods...@ogt.com> wrote: > Hi, > > Thanks in advance for taking the time to read and reply to my email. > > $ make --version > GNU Make 4.0 > Built for x86_64-pc-linux-gnu > > Abstract: > > I'm writing a template makefile for performing similar - but different > - computational biology pipelines and am encountering an issue with > recursive implicit rules.
