c++ undefined reference to destructor - c++

Question

Sorry about this, but I am re-opening this. After sorting the eigen errors, this cropped right back up again. Exactly the same code exactly the same error. (well, the compiler found the eigen headers this time.) So, same question:
I have searched for destructor c++ and undefined reference to no avail. However I am pretty sure this is a fairly simple slip on my part.
Error:

clean : \rm *.o *~ p1
My INCLUDE and LIBS flags are all ok, all other methods in the SASAGeometry class are quite happily defined.
Thanks in advance.

You are not including SASAGeometry.cpp in makefile along with geomTest.cpp. makefile should be something like this:
geomTest : $(GeomTest_OBJS) makefile
$(CC) -o geomTest.o -o SASAGeometry.o $(LIBS) $(INCLUDE) $(CFLAGS) $(geomTest_source) $(LFLAGS)
$(CC) $(LIBS) $(INCLUDE) $(CFLAGS) -o $(BIN)/geomTest geomTest.o $(LFLAGS)
