title: Google protobuf in Linux
body: <p>I'm working with protobuf and Linux. Where is its compiler <code>protoc</code>? I've downloaded the package from the main site, compiled and installed it successfully but I can't find <code>protoc</code> to build my own format file. Where is it?</p>
  <p><strong>UPDATE</strong>
  Here is folder where I built protobuf:</p>
