I am using this C++ Wavelet Libraries, when compiling by g++, I meet some error like this:

I have installed opencv-3.1.0 downloaded from official website on my Ubuntu 15.10, followed by this instruction, and I include all necessary *.h and *.so files in current folder.

Since I am a newbie in C++, I don't know how to fix this problem, would you mind helping me? Thanks!
The problem is that IplImage is much less supported (if at all) in OpenCV3.X.X and the wavelet code that you are wanting to use needs this functionality.
This code on the wavelets example page:
// Creating Image in OPENCV
IplImage *cvImg; // image used for output
CvSize imgSize; // size of output image
imgSize.width = cols_n;
imgSize.height = rows_n;
Is no longer supported and won't work, I imagine this is throughout the framework.
Either downgrade to OpenCV2.X.X and try again or change your wavelets lib to something that supports cv::Mat. The latter is the better option as the C API is long deprecated and not really supported.
