Makefile Formatting

Instructions

When writing or modifying Makefiles, follow these formatting guidelines:

• Each target should have a .PHONY declaration

• Format should follow this pattern:

• .PHONY: target-name on its own line

• target-name: on the next line

• Commands indented with a tab

• Empty line between targets

Example

.PHONY: foo foo: @echo 'foo'

.PHONY: bar bar: @echo 'bar'

When to Use

Apply these guidelines when:

• Creating new Makefile targets

• Modifying existing Makefiles

• Reviewing Makefile code
