title: Bitbake cannot find build files

  <p>This seems to me it cannot compile the source files. When I look in <code>/build-fb/tmp/work/cortexa7t2hf-neon-poky-linux-gnueabi/mainapplication/0.0-r0/MAIN_Application/src/comms/CAN</code> I can see a <code>.o</code> file for every <code>.c</code> file.<a href="https://i.stack.imgur.com/jfcXL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jfcXL.png" alt="enter image description here" /></a></p>
  <p>I was worried that this was old cached data so I deleted this folder and had it re-created. The error remained. So I deleted <code>build-fb/tmp</code> and <code>build-fb/sstate_cache</code>. The error remained. I have a build script that runs make and it runs to completion.</p>

  <p>Edit: The bitbake build shows me the command it is running to compile <code>can_hal.c</code>. If I run this command myself it passes and I see the associated <code>.o</code> file!</p>
