Added core/utility.hpp include

[steevo87]

Necessary to enable calls such as "cv::getTickCount()"

Is there any reason to add this header without any corresponding code that uses it?

[steevo87]

I had to include the header for the original code to compile. Without it, I was getting these errors:

I just double checked, and <opencv2/core/core.hpp> is already included in kfusion/types.hpp. The include chain (core.cpp<kinfu.hpp<types.hpp) should already have included that for you, so I suspect something else is wrong with your build environment.

[steevo87]

Oh OK, so I'm guessing your <opencv2/core/core.hpp> includes a line like this:

#include <opencv2/core/utility.hpp>

Mine doesn't. I'm using the trunk version of OpenCV (last edited: 2014-04-11 19:18:04). Is there a chance that they removed that line of code in between the version of OpenCV you are using and the one I am? In my version of OpenCV I can only find a reference to utility.hpp in core_c.h

[kwaegel]

That's probably it. I think trunk is in the middle of a huge refactoring for OpenCV 3.0. Try using the OpenCV 2.4.9 tag that was recently added.

I last built this with OpenCV commit opencv/opencv@a8cb5c3 from the 2.4 branch.
