# Dynamic Linking: Why It Doesn't Work

![Minimum Rust: 1.0](https://img.shields.io/badge/Minimum%20Rust%20Version-1.0-brightgreen.svg)

Some might suggest using [`prefer-dynamic`](https://doc.rust-lang.org/rustc/codegen-options/index.html#prefer-dynamic) for smaller binaries, but this approach has critical limitations:

- **No stable ABI** - binaries break between Rust versions
- **Deployment complexity** - requires exact library matches
- **Community consensus** - static linking preferred for reliability
