title: GCC installation prefix under Linux
body: <p>What is the recommended installation prefix for GCC under Linux (say default installation of Ubuntu)?
  Would it be the default /usr/local of just /usr?</p>
  
  <p>I am asking because I ran into a problem similar to <a href="https://stackoverflow.com/questions/1952146/glibcxx-3-4-9-not-found">this one</a>.</p>
  
  <p>So, is it really a mistake (not recommended) to install GCC to /usr/local</p>
  
  <p>Thanks.</p>
