mkoctfile & CPP

[knowNothing]

I am trying to call from my "main" file another file that has a function that is using octave "fft" code.
testmclt is the main function and expmod_r_odd has a function called by testmclt. expmod_r_odd calls fft from octave.

Any ideas what's wrong with the makefile?
Thank you

Makefile

The right format requires presence of all .cpp in mkoctfile
Here:

testmclt: testmclt.o expmod_r_odd.o lt_window.o 
  2         mkoctfile --link-stand-alone -o testmclt testmclt.cpp expmod_r_odd.cpp lt_window.cpp
  3 
  4 expmod_r_odd.o: expmod_r_odd.cpp expmod_r_odd.h
  5         mkoctfile -c  expmod_r_odd.cpp 
  6 
  7 lt_window.o : lt_window.cpp lt_window.h 
  8         mkoctfile -c  lt_window.cpp 
  9 
 10 testmclt.o: testmclt.cpp lt_window.h expmod_r_odd.h
 11         g++ -c -I$(OCTAVE_INCLUDE)octave testmclt.cpp 
 12 
 13 clean: 
 14         rm -f *.o testmclt
