title: Why the code doesn't break at the breakpoint in code blocks
body: <p>I followed the instruction from this video to run the code line by line:</p>
  
  <p><a href="http://www.youtube.com/watch?v=6CGH9Z19dS8" rel="noreferrer">http://www.youtube.com/watch?v=6CGH9Z19dS8</a></p>
  
  <p>However, after I pressed F8, it just ran without going to the breakpoint(I couldn't see the yellow triangle). In addition, I also tried "attach to process", and it was the same.</p>
  
  <p>Did I miss anything?(btw, there are multiple files in my project, but I guess that won't be the problem, right? cuz I could do this easily in VS studio. Perhaps, I am not that familiar with codeblocks)</p>
  
  <p>Thanks for help!</p>
  
  <p>If you are interested, this is the debugger log:</p>
