C++ Question

Running a program from a makefile

I received this sample makefile from my professor and I'm trying to run it on Ubuntu but the commands I'm typing won't run it. All the files in the makefile already exist and when I type make, it makes the files but the actual program doesn't run. I have tried to type ./a.out but that doesn't run it either. Please help me with what command to type for the program to run.

# Makefile for Library Management System
CXXFLAGS += --std=c++11

all: div main
rebuild: div clean main

debug: CXXFLAGS += -g
debug: rebuild

main: main.o controller.o view.o library.o publication.o

Is there a file called 'lms'? Try running: ./lms

The things in the makefile after '-o' specify the output filenames. These are the programs you can run.
