A makefile is a file that describes the relationship among the sources of a program used by the make utility to build (compile and link) the target goal (executable, shared object, and more). Makefiles are really important as they help to keep sources organized and easy to maintain. A program, to become executable, must be compiled and linked with other libraries. GCC is the most widely used collection of compilers. The two compilers used in the C and C++ world are GCC and g++ (for the C and C++ programs, respectively). This book will use g++.
Using a makefile to compile and link a program
How to do it...
This section will show how a makefile is written, to compile and run a simple C++ program. We'll develop a simple...
