Make and Makefiles

Automated build tool, for compiling source code. make looks for a file named makefile in your directory and executes it.

Basics

instead of typing gcc -o hellomake hellomake.c hellofunc.c -I. to compile a c++ project, create makefile:

hellomake: hellomake.c hellofunc.c
     gcc -o hellomake hellomake.c hellofunc.c -I.

Finds the respective dependencies and runs a command.
