title: How do I make Emacs recognize bash environment variables for compilation?
body: <p>I'm trying to compile u-boot via Emacs' compilation mode, and it looks like Emacs doesn't know how to find bash environment variables. Even though I set them, and can compile via Emacs shell emulation, compilation mode still tries to compile as if they aren't there.</p>
  
  <p>What do I need to do to make it more environment conscious?</p>
