OpenCV C++ resize() not found

I installed opencv 2.4.9 for macOS and integrated it with Xcode. However, although it finds most functions, when calling the resize() function, I get the build error 'Use of undeclared identifier resize'.

Can anybody please tell me how to fix this?

You don't mention how you are calling it, but there are two resize functions: a member of Mat that changes the number of rows, and cv::resize() that interpolates to resize an image. For the latter you need imgproc.hpp.

#include <opencv2/imgproc/imgproc.hpp>
//...
cv::resize(src, dst, dst.size(), 0, 0, interpolation);
