"multiple target patterns" Makefile error

Question

My makefile fails with error:

Makefile:34: *** multiple target patterns.  Stop. 

What does it really mean, how can I fix this?

(GNU make manual, written by Captain Obvious, isn't helping).

Found it. I had rule in form:

$(FOO): bar 

where FOO was set from shell command that polluted it with error message that contained a colon.

Answer 1

I had it on the Makefile

MAPS+=reverse/db.901:550:2001.ip6.arpa  lastserial:  ${MAPS}     ./updateser ${MAPS} 

It's because of the : in the file name. I solved this with

                       -------- notice                      /    /                     v    v MAPS+=reverse/db.901\:550\:2001.ip6.arpa lastserial:  ${MAPS}     ./updateser ${MAPS}
