make : rule call rule

Question

In a makefile, can I call a rule from another rule?

Similar to:

rule1:
        echo \"bye\"
rule2:
        date
rule3:
        @echo \"hello\"
               


        

Answer 1

There are two advanced functions in GNU Make which can do this, although it should only be used in extenuating circumstances. This SO is top rated in google.

Rule prerequisites are more recommended, but sometimes you need a post-requisite.

GNU Make Call function

GNU Make Eval function

Essentially, Eval lets you build targets on the fly, and Call allows function like "defines" to be created.
