Well, I tried it again and surprise, it worked. My code was segfaulting. For 
some reason when I used the compiler in eclipse/CDT which used:
g++ -O3 -Wall -c -o simulator.o ../simulator.cpp
g++  -o ant_simulator     simulator.o  
Or:
g++ -O0 -Wall -c -o simulator.o ../simulator.cpp
g++  -o ant_simulator     simulator.o  
it wouldn't work, but if I used:
g++ -Wall -o ant_simulator simulator
It would work. Both commands apparently work now, don't know why. Any reason 
why?

Thanks,
