推荐答案

问题似乎是在MultiFormatUPCEANReader类中声明了一个构造函数和析构函数,析构函数,这是造成这个恼人的问题。希望这有助于有人解决他们的编译错误。这是一个可怕的编译器错误,信息很少!

The problem seemed to be that in the class MultiFormatUPCEANReader I had declared a constructor and destructor, but had not written a body for the destructor, this was causing this annoying problem. Hope this helps somebody solve their compile error. This is a terrible compiler error with little information!
