What’s a makefile in C++?

A makefile is a text file that contains instructions for how to compile and link (or build) a set of source code files. A program (often called a make program) reads the makefile and invokes a compiler, linker, and possibly other programs to make an executable file.

What are the advantages of makefile?

A makefile is useful because (if properly defined) allows recompiling only what is needed when you make a change. In a large project rebuilding the program can take some serious time because there will be many files to be compiled and linked and there will be documentation, tests, examples etc.

What is make and Makefile in C?

– It makes codes more concise and clear to read and debug. – No need to compile entire program every time whenever you make a change to a functionality or a class. – Generally, in long codes or projects, Makefile is widely used in order to present project in more systematic and efficient way.

What is wrong with my Makefile for C?

Using C / C++ as an example, when a C/C++ source file is changed, it must be recompiled. If a header file has changed, each C/C++ source file that includes the header file must be recompiled to be safe. Each compilation produces an object file corresponding to the source file.
