But maybe you have some other reason to have your variable main_depend not
shown in your example?
The main reason for trying to do what I am trying to do is the situation
where I have multiple main-documents, each with its own dependencies. If
one of the depending files is updated, I only want the relevant
main-documents to be recompiled, and not all of them.
The following solution does the job, however, this means duplication of
the commands inside the main1.pdf and main2.pdf block. My intent was
thus to try to avoid this and parametrize into a single %.pdf block.
-8<-----------------------------------------
texfiles = main1.tex main2.tex
main1_depend = section1.tex section3.tex
main2_depend = section2.tex section1.tex
all_pdf = $(texfiles:.tex=.pdf)
all: $(all_pdf)
main1.pdf: main1.tex $(main1_depend)
@echo "All prerequisites:" $^
touch $@
main2.pdf: main2.tex $(main2_depend)
@echo "All prerequisites:" $^
touch $@
-8<-----------------------------------------
Maybe there exist better solutions to achieve the desired effect?
Best regards,
