问题描述

编译iPhone项目时出现以下错误。任何人都知道我可以如何解决它？
vtable for oned :: MultiFormatUPCEANReader，引用自：
__ZTVN4oned23MultiFormatUPCEANReaderE $ non_lazy_ptr in MultiFormatUPCEANReader.o
ld：未找到符号
collect2：ld返回1退出状态

I was getting the following error compiling an iPhone project. Anybody know how I may fix it? "vtable for oned::MultiFormatUPCEANReader", referenced from: __ZTVN4oned23MultiFormatUPCEANReaderE$non_lazy_ptr in MultiFormatUPCEANReader.o ld: symbol(s) not found collect2: ld returned 1 exit status

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!
