OpenCV bindings for Go

I was working with the OpenCV bindings for Go, and came across an the following issue from the get go:

1: error: 'CV_INPAINT_TELEA' undeclared (first use in this function)
1: note: each undeclared identifier is reported only once for each function it appears in
1: error: 'CV_INPAINT_NS' undeclared (first use in this function)
1: error: 'cvInpaint' undeclared (first use in this function)

After some poking around, I found that the reason for this is that the directory structure has changed for OpenCV 2.4. The solution to the problem was fairly simple. Open up terminal, and navigate to

cd /usr/share/go/src/pkg/code.google.com/p/go-opencv/trunk/opencv

This directory may differ for you, and in that case, just check your GOPATH.

Open the file opencv.h and simply comment out/delete the conditional statement at the top of the page so that you’re left with only

//  OpenCV 2.4.x
#   include <opencv/cv.h>
#   include <opencv/highgui.h>
#   include <opencv2/photo/photo_c.h>
#   include <opencv2/imgproc/imgproc_c.h>

Save the file, and that should be it.
