The easiest way to build new applications or test programs is to simply
add them to the gnuradio/src/gnu/examples directory and edit
Makefile.am, then type "make".  The Makefile should be regenerated
from Makefile.am, and then the appropriate magic will be performed.

If you look in Makefile.am, you'll see two places that you need to edit.

(1) add myprogram to the list starting with...

noinst_PROGRAMS         =               \
        myprogram                       \
        adc3_fft                        \
        adc3_fftavg                     \

(2) add the two lines that instruct make how to build it:

myprogram_SOURCES       = myprogram.cc
myprogram_LDADD         = $(top_builddir)/src/gnu/lib/libgnuradio.la


Then type "make".

We won't hold it against you ;-)
