title: Running Ubuntu Eclipse C++ Helloworld
body: <p>I'm trying to run a Hello world C++ on Eclipse on Ubuntu 12.04. I installed g++ and wrote this code:</p>
  
  <pre><code>#include&lt;vector&gt;
  #include&lt;string&gt;
  #include &lt;iostream&gt;
  using namespace std;
  int main()
  {
      cout &lt;&lt; "Hello World" &lt;&lt; endl;
      return 0;
  }
  </code></pre>
  
  <p>Compile output:</p>
  
  <pre><code>**** Build of configuration Debug for project TopCoder ****
  
  make all 
  make: Nothing to be done for `all'.
  
  **** Build Finished ****
  </code></pre>
  
  <p>Run output message:</p>
  
  <pre><code>Launching TopCoder has encountered a problem
  Error starting process

  </code></pre>
  
  <p>when I put the source code on ext4 drive it builds and run
  I changed </p>
  
  <pre><code>proc            /proc           proc    nodev,noexec,nosuid 0       0
  </code></pre>
  
  <p>in /etc/fstab to</p>
  
  <pre><code>proc            /proc           proc    dev,exec,suid 0       0
  </code></pre>
  
  <p>But no usefulness.</p>
