title: Error installing protocol buffers compiler (protoc) with java in linux
body: <p>I tried to install protocol buffer compiler  - Java in Ubuntu through reading README.txt file .
  First i typed the following commands:</p>
  
  <pre><code>./configure
  </code></pre>
  
  <p>then </p>
  
  <pre><code>make
  </code></pre>
  
  <p>then</p>
  
  <pre><code>make check
  </code></pre>
  
  <p>then</p>
  
  <pre><code>make install
  </code></pre>
  
  <p>then</p>
  
  <pre><code>protoc --java_out=src/main/java -I../src \../src/google/protobuf/descriptor.proto
  </code></pre>
  
  <p>In this last step i have a problem that I don't know which paths should I put in this command.</p>
