Re: [Boost-users] dynamic_pointer_cast doesn't work as expected

Diego Bernini:

Hi, see these lines:

boost::shared_ptr<Executor> executor(&(createExecutor(subclass,name))); if(!executor) { throw LoadingClassException("createExecutor function of\""+subclass+"\" return null."); } //executor points to an object of class ExecDebugger that IS A Executor //(it's a plugin loaded at run time via Qt)

boost::shared_ptr<Nameable> a=executor; boost::shared_ptr<Executor> sp;

sp=boost::dynamic_pointer_cast<Executor>(a);

It's possible that dynamic_cast doesn't work across dynamic libraries on your platform.
