title: How to edit source codes on Yocto project, and rebuild it?
body: <p>I'm new at Yocto project.</p>
  
  <p>The problem is rebuilding with source editing.</p>
  
  <p>The flow which I tried is below.</p>
  
  <ol>
  <li><p>Build Yocto Project ( bitbake core-image-weston )</p></li>
  <li><p>After building, I edited weston source code.
  ( build/tmp/work/aarch64-poky-linux/weston/1.9.0-r0/git/ivi-shell/hmi-controller.c )</p></li>
  <li><p>Re-Build Yocto Project.
  ( I don't know how can I rebuild it, so I tried many ways. )</p>
  
  <ol>
  <li>bitbake core-image-weston</li>
  <li>bitbake weston</li>
  <li>bitbake weston -c -f compile
  bitbake weston -c -f deploy</li>
  <li>bitbake weston -c -f rebuild</li>
  <li>bitbake weston -c -f build</li>
  </ol></li>
  <li><p>I checked output rootfs : core-image-weston-.tar.bz 
  But it doesn't changed.
  (I added a wrong codes which cause build error, but build error is not occured ever! )</p></li>
  </ol>
  
  <p>So, I hope to know how can I edit source code(weston) and build it correctly.
  finally, I hope to get properly built rootfs.</p>
  
  <p>Thank you.</p>
