title: Boost librairies not found but compilation is ok
body: <p>I am trying to use filesystem from boost in c++</p>
  
  <p>It seems the compilation is ok when using </p>
  
  <blockquote>
    <p>"c++ -c Analyse.c -o Analyse.o -g -W -Wall -L/usr/local/lib -lboost_filesystem -lboost_system"</p>
  </blockquote>
  
  <p>However I have the following error when trying to execute my code :  </p>
  
  <blockquote>
    <p>"error while loading shared libraries: libboost_filesystem.so.1.54.0: cannot open shared object file: No such file or directory", a find / -iname "libboost_system.so.1.54.0</p>
  </blockquote>
  
  <p>I had some issues to install boost (I first installed the 1.49 and after that 1.54) so I was wondering if there could be any conflict between the 2 version ?</p>
  
  <p>P.S : btw a <code>"find / -iname "libboost_system.so.1.54.0"</code> gave me the following</p>
  
  <pre><code>/usr/include/boost/boost_1_54_0/bin.v2/libs/system/build/gcc-4.7/release/threading-multi/libboost_system.so.1.54.0
  
  /usr/local/lib/libboost_system.so.1.54.0
