title: Building Caffe on Ubuntu: make can't find Boost's include files
body: <p>I am following <a href="http://caffe.berkeleyvision.org/installation.html" rel="noreferrer">these instructions</a> to install and build Caffe along with its dependencies. I built Boost and got this at the end:</p>
  
  <pre><code>The following directory should be added to compiler include paths:
     /home/ubuntu/Caffe/boost_1_57_0
  The following directory should be added to linker library paths:
     /home/ubuntu/Caffe/boost_1_57_0/stage/lib
  </code></pre>
  
  <p>When I run <code>make all</code> in the caffe directory, I get this:</p>
  
  <pre><code>CXX src/caffe/blob.cpp
  In file included from ./include/caffe/blob.hpp:8:0,
               from src/caffe/blob.cpp:4:
  ./include/caffe/common.hpp:4:32: fatal error: boost/shared_ptr.hpp: No such file or directory
  compilation terminated.
  make: *** [.build_release/src/caffe/blob.o] Error 1
  </code></pre>
  
  <p>What do I need to modify for it to find the include (and lib) files? A specific environment variable? A setting in caffe's Makefile? Something else?</p>
