我如何在VC ++(MFC)中通过FANN实现神经网络

问题描述

我已经制作了libfann并将其附加到我的项目中
而且我已经编写了这些代码，但是由于编译，它给出了这3个链接器错误！为什么?



错误8错误LNK2019:在函数"public:void __thiscall CTTSPDlg :: OnBnClickedButton2(void)"中引用了未解析的外部符号__imp__fann_destroy @ 4(?OnBnClickedButton2 @ CTTSPDlg @@ QAEXXZ)TTS-PDlg.obj

错误10致命错误LNK1120:2个未解决的外部组件D:\ TTS \ Programming \ Delete1 \ Debug \ TTS-P.exe

I have made libfann and attached it to my project
and also I''ve wrote these code, but due the compilation it gives these 3 linker errors! Why?

#include "floatfann.h"
.
.
.
{
    struct fann *ann = fann_create_standard(3,2,4,1);

    fann_destroy(ann);
}

推荐答案

#ifdef _MSC_VER                         /* MicroSoft C++ compiles, declare externals as "C" calling standard */
#ifdef __cplusplus
extern "C" {
#endif
#endif

// place the declarations / function prototypes for fann_create_standard and fann_destroy here

#ifdef _MSC_VER
#ifdef __cplusplus
}
#endif
#endif
