Hi everyone
  I meet this error:
 "class.cpp:89: error: no matching function for call to 'make_shared(const boost::weak_ptr<zeitgeist::Core>&)'
 and the code is:
 return make_shared(mCore);
 I'm using gcc 4.3.1 and boost 1.36.0. I tried to solve the problem by using shared_ptr<Core>(mCore) but got
 a run-time error. Could someone help me?
