Makefile refuses to match target patterns under strange circumstances

I encountered some strange behavior, when one runs

make hello-there

and the makefile is

hello-%:
    @echo hi $*

I get

hi there

But when the makefile is just

hello-%:

I get

make: *** No rule to make target `hello-there'.  Stop.

In the second case you are not definign any rule for hello-%.

From chapter 5 of the documentation:

Each line in the recipe must start with a tab, except that the first recipe line may be attached to the target-and-prerequisites line with a semicolon in between

You have to ways of solving this:

  • Add a semicolon at the end of the line defining the target name:

    hello-%: ;

  • Add a line containing only a tab below the the one defining the target name
