title: Selecting OSX SDK version in Eclipse and Makefiles
body: <p>I have a development Mac running 10.5. This causes my apps to not work in 10.4 (Google "_nsdefaultrunloopmode tiger"). I read the solution is to install the 10.4 SDK and compile against that. I have it installed (at least I have /Developer/SDKs/MacOSX10.4u.sdk)</p>
  
  <p>Now I can't find a way to actually use that - I'm doing two things:</p>
  
  <p>1) Compiling a library (SDL) using Makefiles<br>
  2) Compiling the program using Eclipse</p>
  
  <p>I can't find a way to specify the SDK version in either of these two scenarios. Documentation doesn't seem to mention how to do it, so I'm thinking I'm overlooking something obvious. Any help?</p>
