# Arrow C++ Thirdparty Dependencies

See the "Build Dependency Management" section in the [C++ Developer
Documentation][1].

## Update versions automatically

There is a convenient script that update versions in `versions.txt` to
the latest version automatically. You can use it like the following:

```console
cpp/thirdparty/update.rb PRODUCT_PATTERN1 PRODUCT_PATTERN2 ...
```

For example, you can update AWS SDK for C++ related products' versions
by the following command line:

```console
cpp/thirdparty/update.rb "AWS*" "S2N*"
```
