Hm, interesting that you’d be failing on the `fdb_java` line. That library should be included within the jar (unless you’re running on some system we don’t support, but there is a Linux so file, a macOS dylib, and a Windows DLL included).

There is also separately an `fdb_c` dependency that you’ll need to include. There’s no way to run the FoundationDB client without having the dependency around (short of [running a separate proxy service](https://forums.foundationdb.org/t/proxy-layer-for-securing-the-cluster/1611)), but you don’t need the user to have installed the library, necessarily. On Linux, you should be able to set the `LD_LIBRARY_PATH` environment variable to include the path to a directory where you have included the library. Less tested, but also, I think on all platforms, if you set the `FDB_LIBRARY_PATH_FDB_C` Java system property to the path of the library, then I think that, too, should load the C library. (Note that this is undocumented, and I’m not sure if it was really intended to be something use in real environments.)

You can download the C library from our website:

```auto
https://www.foundationdb.org/downloads/${version}/${os}/libfdb_c_${version}.${ext}

```

Where `${version}` is the FDB version, `${os}` is your operating system (linux, macOS, or windows), and `${ext}` is the platform specific dynamic library file extension.
