title: error: iostream: No such file or directory
body: <p>When I try to compile c++ code, my include statements don't seem to be working. I haven't been c++ programming on my computer in a while, but this has never happened before. </p>
  
  <p>I made a minimal test script, and upon compiling (g++ infile.cpp -o outfile.out) I get: "error: iostream: No such file or directory"    </p>
  
  <p>The same problem happens for vector, string, and I'm guessing other libraries. </p>
  
  <p>Why isn't g++ finding the appropriate libraries? </p>
  
  <pre><code>#include &lt;iostream&gt;
  
  int main() {
      return 0;
  }
  </code></pre>
