The issues are with the backend_src Makefile which looks like this:

----------------
# Makefile for cli_backend

CC=gcc

OBJECTS=\
        obj/backend.o \
        obj/caller.o \
        obj/core_functions.o \
        obj/file_functions.o \
        obj/essid_encoder.o

CFLAGS += -Wall -Wextra -Iinclude -g -O2
#CFLAGS += -Wall -Wextra -Iinclude -ggdb

all: $(OBJECTS) bin/backend

clean:
        rm -f $(OBJECTS) bin/backend

bin/backend: $(OBJECTS)
        $(CC) -o $@ $(OBJECTS)

obj/%.o : src/%.c
        $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<

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

Problems with this: OBJECTS doesn't contain automated_scanner.o, leading
to a link failure and the linker command (bin/backend target) is missing
a -lm in order to link with the math library (for the pow
function). Further, the obj and bin directories don't exist.

Below is a git-created patch addressing all this (using Timo Burmester's
idea of creating the directories via Makefile as that's less manual
work):

In order to apply this, save it to a file, say, /tmp/nm.diff. Go to the
top-level netman directory and run

patch -p1 </tmp/nm.diff

And check the modified backen_src/Makefile into git with some commit
message of your liking.

NB: The patch is a bit overkill here but as the procedure is pretty much
standard for communicating changes to some source tree, I thought you'd
be interested in it.
