        * [libprotoc-c](http://code.google.com/p/protobuf-c/) version 0.14 or 0.15 (use --disable-protoc option in its ./configure to build only the library).

        * `./configure` - use `./configure --help` for switches. Defaults to build using PolarSSL, no test certificate, `/dev/urandom` as random source.
        * `make`
