How to run a bash script from a Makefile?

Question

I have a Makefile from which I want to call another external bash script to do another part of the building. How would I best go about doing this?

Answer 1

Just like calling any other command from a makefile:

target: prerequisites
    shell_script arg1 arg2 arg3

Regarding your further explanation:

.PHONY: do_script

do_script: 
    shell_script arg1 arg2 arg3

prerequisites: do_script

target: prerequisites
