title: C++ Makefile that includes ddd debugger option
body: <p>I'm kind of new to Makefiles and i'm trying to include a debugger option in my makefile that opens the debugger when I type "make debug." However, that command returns an error. I already have the ddd debugger installed in my virtual machine. This is my makefile below. Any help? </p>
  
  <pre><code>main: main.cpp puzzle.cpp fuse.cpp
      g++ --std=c++11 -o main main.cpp
      ./main
  clean:
      -rm -f *.o main
  debug:
      g++ --std=c++11 -g debug main.cpp puzzle.cpp fuse.cpp ddd debug
  </code></pre>
