I'm trying to build OpenCV 3.0 with VTK 6.2 on mac OSX 10.9 but the build fails at opencv_viz. The issue is with the objective c file vtkCocoaInteractorFix.mm which was added on the 8th of Feb in commit 5dc17f5. The error given is

No member named 'GetCocoaServer' in 'cv::viz::vtkCocoaRenderWindowInteractorFix'

This is because GetCocoaServer has been moved from vtkCocoaRenderWindowInteractor to vtkCocoaRenderWindow in VTK 6.2. This alteration to VTK happened almost a year ago according to the gitHub commit a3e9fc9. Is anyone else having this issue? Does anyone know of a workaround or have any suggestions for fixing the code?

CV_CAP_IOS should contain an integer which identifies the device io stream. The default io stream is usually 0 so the following should work.

int CV_CAP_IOS = 0; // Just a guess for the camera io stream

Hi.

First.

The gsoc 2012 examples use the most up to date version of openCV. You can clone the git repository as follows:

Launch GIT client and clone OpenCV repository from here: http://github.com/itseez/opencv

In MacOS it can be done using the following command in Terminal:

cd ~/<my_working _directory=""> git clone https://github.com/Itseez/opencv.git

Building OpenCV from source using CMake, using the command line

Make symbolic link for Xcode to let OpenCV build scripts find the compiler, header files etc.

    cd /
    sudo ln -s /Applications/Xcode.app/Contents/Developer Developer

Build OpenCV framework

    cd ~/<my_working_directory>
    python opencv/ios/build_framework.py ios

If everything’s fine, a few minutes later you will get ~/<my_working_directory>/ios/opencv2.framework. You can add this framework to your Xcode projects.

Second.

The import statement is

#import < opencv2/highgui/cap_ios.h >

for the camera stuff

Hope this helps.
