I am getting the following error.. How to rectify this error?

推荐答案

链接器找不到函数使用具有以下类型的C ++编译器进行编译:

The linker can''t find a function compiled with a C++ compiler with the protype:

int ScrambledActName(char *);

您代码中的任何位置，或您要链接的库.

在我的头顶上，有几个原因可能会导致错误...

-您尚未实现该功能-请去编写它！

-有人为您提供了一个库，但没有提供工作所需的所有依赖项

-有人编写了该函数，但使用C编译器而不是C ++编译器进行了编译.解决这一问题的方法是找到函数在代码中的原型，并在其外部加上"C"前缀，以告知编译器它是使用C编译器编译的函数:

anywhere in your code, or the libraries you''re linking with.

Of the top of my head there are several reasons this might go wrong...

- You didn''t implement the function - go and write it!

- Someone else supplied you a library but didn''t give you all the dependencies it needed to work

- Someone wrote the function but compiled it with a C compiler, not a C++ one. The way around this one is to find where the function is prototyped in your code and preface it with extern "C" to tell the compiler it''s a function compiled with a C compiler:

extern "C" int ScrambledActName( char * );

-该函数在某处的原型不正确.例如，原始程序员可能已经使用const参数对其进行了原型设计.


不知不觉就很难再发表评论了.

干杯，

- The function was prototyped incorrectly somewhere. The original programmer might have prototyped it with a const parameter for example.


Without knowing any more it''s a bit hard to comment any further.
