-DMODELDIR="pkg-config --variable=modeldir pocketsphinx "

This doesn't work in makefile the way it works in the command line. You need
to escape the double quote otherwise it will be removed. I suggest you to try
the following makefile:

obj=hello_ps
modeldir=$(shell pkg-config --variable=modeldir pocketsphinx)
flags=$(shell pkg-config --cflags --libs pocketsphinx)

$(obj):$(obj).c
        gcc $(obj).c -o $(obj) -DMODELDIR=\"$(modeldir)\" $(flags)

I really do as your instrucion ,but the gcc still gives errors as
below:
hello_ps.c: In function ‘main’:
hello_ps.c:10: error: ‘MODELDIR’ undeclared (first use in this
function)
hello_ps.c:10: error: (Each undeclared identifier is reported only
once
hello_ps.c:10: error: for each function it appears in.)
hello_ps.c:10: error: expected ‘)’ before string constant
make: *** Error 1
Now i am totally confused ....Thanks a lot!

Well, my instruction includes "Try to understand what really happens in a
makefile". This step will be particular useful for you.
