title: Boost chrono run_timer undefined reference
body: <p>I am trying to compile the run_timer_example.cpp example in the boost distribution (1.47.0) and I am getting this using the Intel compiler:</p>
  
  <pre><code>$ icc -I/usr/local/include -L/usr/local/lib -lboost_system -lboost_chrono run_timer_example.cpp
  /tmp/iccUIv4Av.o: In function `main':
  run_timer_example.cpp:(.text+0x33): undefined reference to `boost::chrono::run_timer::run_timer(boost::system::error_code&amp;)'
  run_timer_example.cpp:(.text+0xa5): undefined reference to `boost::chrono::run_timer::report(boost::system::error_code&amp;)'
  </code></pre>
  
  <p>and using GNU:</p>
  
  <pre><code>$ g++ run_timer_example.cpp -I/usr/local/include -L/usr/local/lib -lboost_system -lboost_chrono
  /tmp/cc3ZOLLF.o: In function `main':
  run_timer_example.cpp:(.text+0x16): undefined reference to `boost::chrono::run_timer::run_timer(boost::system::error_code&amp;)'
  /tmp/cc3ZOLLF.o: In function `boost::chrono::run_timer::~run_timer()':
  run_timer_example.cpp:(.text._ZN5boost6chrono9run_timerD2Ev[_ZN5boost6chrono9run_timerD5Ev]+0x3b): undefined reference to `boost::chrono::run_timer::report(boost::system::error_code&amp;)'
  collect2: ld returned 1 exit status
  </code></pre>
  
  <p>What am I missing?</p>
  
  <p>Edit: I gave up in the end.  It appears my install of Ubuntu cannot deal with compiling Boost 1.47.0 correctly and thus I cannot use it.  Shame. </p>
