Mock Makefile Generator

Used by developers, writers, and creators worldwide.

A mock Makefile generator produces an example Makefile with common targets for building, testing, and running a project. Make is a venerable build tool, and a Makefile gives a project a simple, memorable command interface — make build, make test — regardless of the underlying stack. This tool emits a valid Makefile with the usual targets. Click generate and copy it into a project or a tutorial. It is ideal for learning Make, scaffolding a project, and documenting commands. The Makefile follows real conventions, including a .PHONY declaration for targets that are not files and tab-indented recipes. One classic gotcha: Make requires recipe lines to be indented with a real tab, not spaces, or it will error — so preserve the tabs when you copy it. Adapt the commands to your own toolchain, and a small Makefile becomes a tidy front door to your project's common tasks.

FAQ

what does a Makefile do

A Makefile defines named targets — like build, test, and run — each with a recipe of shell commands. Running make build executes that target's commands, giving a project a simple, consistent command interface regardless of its language or stack.

what is .PHONY for

A .PHONY declaration marks targets that are not actual files, like build or clean. Without it, Make might skip a target if a file of the same name exists. Declaring them phony ensures the target always runs when invoked.

why does Make need tabs

Make requires recipe lines to be indented with a real tab character, not spaces — a quirk of its design. Using spaces causes a "missing separator" error. When copying a Makefile, preserve the tabs or it will not run.
