What is GNU Make?

Compile and run your programs with ease via this automation tool.

A Makefile is a special file used in software development projects to automate the process of building executable programs or libraries from source code. It typically contains a set of instructions, which specify how to compile and link the source files into the final application.

Examining a Basic Example

1. App.class: App.java
• Compiles App.java into App.class if it's outdated.


2. TestApp.class: App.class TestApp.java
• Compiles TestApp.java into TestApp.class, including dependencies.


3. run: App.class
• Executes java App if App.class is present.


4. test: TestApp.class
• Executes JUnit tests using java -jar ../junit5.jar -cp . -c TestApp if TestApp.class is present.


5. Mercury:
• Prints "Hello Mercury" when invoked.
