title: Porting OpenThread to IAR tool set
body: <p>I am new to OpenThread and am looking into porting OpenThread to IAR IDE. I wanted to know if there is any documentation, or where I might find more information on the different defines that are used(how they get enabled, what Thread device would use them, etc).  </p>
  
  <p>Needless to say, I am also inexperienced with the gnu autoconf toolset, and have been attempting to figure it out...  I have noticed that there seems to be two categories of defines, those that start with "OPENTHREAD_ENABLE_" that tend to be compiler enabled defines (-DOption pushed by autoconf) and those that are in the openthread-core-config.h (OPENTHREAD_CONFIG_).  </p>
  
  <p>So in order to build say, a router enabled end device, what all defines are required (ignoring optional features)? (and secondary question, which files would be required?)...  When building with the autoconf environment, the file selection tends to change depending on the type of thread target being built...
  I have been using the cc2538 project as an example to attempt to port to IAR...</p>
  
  <p>I've used the command </p>
  
  <pre><code>make SHELL="/bin/bash -x" -f examples/Makefile-cc2538
  </code></pre>
  
  <p>In an attempt to see all compile lines, but I still seem to be missing something, since my builds still fail.. (linking)...</p>
  
  <p>Any help is greatly appreciated</p>
