# Runtime Dependencies

If running `ouch` results in a linking error, it means you're missing a runtime dependency.

If you're downloading binaries from the [releases page](https://github.com/ouch-org/ouch/releases), try the `musl` variants, those are static binaries that require no runtime dependencies.

Otherwise, you'll need these libraries installed on your system:

* [libbz2](https://www.sourceware.org/bzip2)
* [libbz3](https://github.com/kspalaiologos/bzip3)
* [libz](https://www.zlib.net)

These should be available in your system's package manager.
