title: How Does gcc on Solaris Find Its Libraries?
body: <p>I'm trying to install 'quadrupel', a library that relies on ffmpeg on Solaris x86.</p>
  
  <p>I managed to build ffmpeg and its libraries live in /opt/gnu/lib and the includes are in /opt/gnu/include but when I try to build quadrupel, it can't find the ffmpeg headers.</p>
  
  <p>What flags/configuration is required to include those two directories in the proper search paths for libraries and includes? I'm not much of a Makefile hacker.</p>
