Question

因为几个小时后我在使用Windows 7下的c ++编程时传递引用有一些问题：

（我正在使用的代码被复制）

我正在使用main调用头文件中定义的一些函数。传递的值是静态引用，例如：

static void generate(const int &_N,const int &_M, const cv::Mat &_TRANS,const cv::Mat &_EMIS, const cv::Mat &_INIT, cv::Mat &seq, cv::Mat &states) {
    std::cout << "Function generate called!" << std::endl; 
}

如果我清理并构建我的项目（我正在使用NetBeans），我会收到以下错误：

[...]

有更多这些＆＃34;未定义的引用...＆＃34;我在这里删了。

我的问题是什么？

在Windows 7下传递C ++编程中的引用不起作用：未定义的引用
