Re: help with loop in a Make file

[Jacques Menu Muzhic]

Hello Federico,

The actual syntax for a loop in Make is different that that of bash, as is its 
meaning by the way, see: 
        
        
https://www.gnu.org/software/make/manual/html_node/Foreach-Function.html.

But what you need is probably a pattern like this, where ‘%’ is a place holder 
as explained in:

#  In the actions:
#               $@  is the target to be built
#               $<  is the first prerequisite

intervista_%.pdf : pdf2ps $@
