Problem with substitution reference

[Greg Ortiz]

Getting a 'target pattern contains no '%' from running a simple make.  Running make from OpenSuse using GNU make 3.8.1.  Any help would be greatly appreciated.

 

Makefile

------------------

hello:

    echo $@

    make -f include.mk hello

 

include.mk

------------------

hello: hello.o

     cc -c hello.c

 

hello.o: $${@:%.o=%.c}

  cc -c hello.c
