How to make opencv2.framework with opencv_contrib

From OpenCV 3.0.0-rc1, --contrib option is added to platforms/ios/build_framework.py.
As a result, we can specify opencv_contrib's path by this option. https://github.com/Itseez/opencv/blob...

So, I tried to build opencv2.framework with opencv_contrib in the following steps.

  1. get the code of opencv-3.0.0-rc1.
  2. get the code of opencv_contrib.
  3. run python opencv-3.0.0-rc1/platforms/ios/build_framework.py ios to generate opencv2.framework.
  4. run python opencv-3.0.0-rc1/platforms/ios/build_framework.py --contrib opencv_contrib ios_contrib to generate opencv2_contrib.framework.

And, I made iOS project using Xcode. And, I imported opencv2.framework and opencv2_contrib.framework to my project.

After that I added the following code to my project.

#import <opencv2/core.hpp>
#import <opencv2/features2d.hpp>
#import <opencv2_contrib/xfeatures2d.hpp>

But, the following build error occurs.

/Users/xxxx/dev/ios_contrib/opencv2_contrib.framework/Headers/xfeatures2d.hpp:43:10: 'opencv2/xfeatures2d/nonfree.hpp' file not found

Is this procedure is wrong to use opencv2.framework with opencv_contrib?

I have same problem,and you can't

import opencv2/module.hpp

from opencv2_contrib.framework,instead you should import like this

opencv2_contrib/module/module.hpp

I found other solution. I replaced my "build_framework.py".
