title: error while loading shared libraries: libboost_system.so.1.45.0: cannot open shared object file: No such file or directory
body: <p>I am building a C++ executable on Linux. The executable links into some boost libraries.</p>
  
  <p>This is the output when I attempt to run the binary:</p>
  
  <pre><code>root@yourbox:~/work/dev/c++/projects/testfgci/dist/Debug/GNU-Linux-x86$ ./testfgci 
  ./testfgci: error while loading shared libraries: libboost_system.so.1.45.0: cannot open shared object file: No such file or directory
  </code></pre>
  
  <p>I then run ldd on the binary to check dependencies:</p>
  
  <pre><code>root@yourbox:~/work/dev/c++/projects/testfgci/dist/Debug/GNU-Linux-x86$ ldd testfgci

  <p>I am not sure why the liboos_system.sl.1.45.0 SO is not found. I built it successfully a little earlier on today. Can anyone explain?</p>
