title: Why is my c++ build saying I have in "invalid character in path"?
body: <p>I'm trying to build my first c++ program, and I'm using the Eclipse plugin for it. I'm using their example &quot;Hello world&quot; program. It doesn't show any errors, but when I hit build, it logs the following:</p>
  <blockquote>
  <p>**** Rebuild of configuration Debug for project Hello world ****</p>
  <p>**** Internal Builder is used for build               ****</p>
  <p>Build error</p>
  <p>Illegal character in path at index 5: Hello world.exe</p>
  </blockquote>
  <p>Does anybody know why this error is occurring, or how to fix it?</p>
  <p>Thanks :)</p>
  <p>EDIT:</p>
  <p>I tried creating my own, and I'll add a pic below of my file structure, but now I get the following error: (im assuming its an error as it still won't run, but it might not be)</p>
  <blockquote>
  <p>**** Build of configuration Debug for project Project ****</p>
  <p>**** Internal Builder is used for build               ****</p>
  <p>Nothing to build for Project</p>
