我正在使用this C++ Wavelet Libraries，在用g ++编译时，我遇到了这样的错误：

我已经在我的Ubuntu 15.10上安装了从官方网站下载的opencv-3.1.0，然后是this instruction，我在当前文件夹中包含了所有必需的* .h和* .so文件。

由于我是C ++的新手，我不知道如何解决这个问题，你介意帮我吗？谢谢！
答案 0 :(得分：0)
问题是在OpenCV3.X.X中支持IplImage（如果有的话），并且您想要使用的小波代码需要此功能。
wavelets示例页面上的代码：
// Creating Image in OPENCV
IplImage *cvImg; // image used for output
CvSize imgSize; // size of output image
imgSize.width = cols_n;
imgSize.height = rows_n;
不再支持并且不会工作，我想这是贯穿整个框架的。
要么降级到OpenCV2.X.X并重试，要么将小波库更改为支持cv :: Mat的内容。后者是更好的选择，因为C API长期被弃用且不受支持。
