Qt 机器学习库OpenCV 2.1

我已经试着编译了文档的最新版本。我已经将库搜索路径设置为opencv\lib，还设置了include路径。我已经包含了-lml机器学习库，但是我发现了以下错误：

对CvEM:：CvEM的未定义引用

如果我对CvEM em_模型进行注释，代码将编译：

// CvEM em_model;
CvEMParams params;

CvEMParams不会导致错误，因此我认为include路径是可以的。有人知道如何解决这个问题吗

如果我在VisualStudio中运行代码，它将运行得非常完美

编辑：添加其他信息

My.pro文件具有以下命令

INCLUDEPATH += C:/OpenCV2.1/include

INCLUDEPATH += C:/OpenCV2.1/include/opencv

LIBS += -L"C:/OpenCV2.1/bin" -lcv210 -lcxcore210 -lcvaux210 -lhighgui210 -lml210 -lcxts210 \-lnetapi32`

我的汇编如下所示：

只要用qt版本的mingw重新编译发行版，它就可以工作了

您使用的是哪个版本的OpenCV？您用来编译的完整命令是什么？另外，你提供的链接坏了，你能再检查一下吗。谢谢你，克里斯，我已经更新了我的帖子。我期待着收到你的来信。
