How can I optimize my Makefile for faster builds?

You can optimize your Makefile by minimizing unnecessary rebuilds, using parallel builds, and leveraging built-in functions.

What do you mean by minimizing unnecessary rebuilds?

Minimizing unnecessary rebuilds involves ensuring that your targets only rebuild when their dependencies change. Use proper dependency tracking.

Are there specific flags I should use for parallel builds?

Yes, you can use the -j flag followed by the number of jobs you want to run in parallel, like make -j4.

Can you give me an example of a well-optimized Makefile?

Sure! A simple example would include using variables for compiler flags and defining clear dependencies to avoid redundant builds.
