Advantages of source release over binary release?

Question

I now understand the major differences between source release and binary release of a software. A good question here.

I needed to install Node.js on a Linux machine, and chose binary release because it requires no compilation/installation. I downloaded the tar, unzipped the file, and it's ready-to-go.

My question is, when both choices are available, for what reasons would a person choose source over binary?

The only thing I can think of is that the person wishes to read/study the source code.

Answer 1

You need a source release when:

• There are no pre-compiled binaries for your platform. You have to build them yourself.
• You want to compile it into your project.
• You want to make changes (although you'd better be using git for that).
• You want to comply to the open source license when using it in your product.
  Eg: with gpl you must provide the source when someone asks.
