[boost] Error Handling issue in NonCopyable Interface

Hello, I am having error handling issues that is in regards to the NonCopyable Interface library. Here is the source code: #include #include <iostream> class A : public boost::noncopyable { public:  A() { std::cout << "In A \n" << std::endl; }  class AnError  {};  void Func()  {   if () //error condition    throw AnError();  } }; int main() {  try  {   A object1;   A object2(object1);   object1 = object2;  }  catch (A::AnError)  {   //tell user about error.  }     return 0; } } So far, I have tried on the forums in CPlusPlus.com and MSDN, but no responses. Since that Boost.org has created and authored the NonCopyable.hpp library, I would like to get some assistance. Can anybody give me some solutions on how to suppress any compilation errors? Thanks in advance.  Email me back at the Cc: if you have any answers or comments with detailed information and examples. John P.
