Answer 1

I had the same issue ...

I already have rules for check, test and build... but wanted to string them together...

Easy I thought...

.DEFAULT_GOAL := fullcheck
    $(MAKE) check
    $(MAKE) test
    $(MAKE) build

But no commands commence before first target. Stop.

What I had omitted was, the name of the rule. It should be like this.

.DEFAULT_GOAL := fullcheck
fullcheck:
    $(MAKE) check
    $(MAKE) test
    $(MAKE) build
