Makefile If-Then Else and Loops

Question

Can someone explain how to use if-then statements and for loops in Makefiles? I can\'t seem to find any good documentation with examples.

Answer 1

You do see for loops alot of the time, but they are usually not needed. Here is an example of how one might perform a for loop without resorting to the shell

LIST_OF_THINGS_TO_DO = do_this do_that 
$(LIST_OF_THINGS_TO_DO): 
       run $@ > $@.out

SUBDIRS = snafu fubar
$(SUBDIRS):
     cd $@ && $(MAKE)
