I also do this in our project, Real Colors (Android and iPhone app). For iOS we wrapped all the code in a static library that we link in the iOS app. We also include the opencv2.framework in the app.

It is possible to have one codebase for the OpenCV code and then link it to whatever platform you want: Android, iPhone, PC, Mac.

I am also trying to figure this one out. I am exploring two solutions:

1. There is a readme.txt file in opencv/ios with instructions on builiding the files for the framework.

2. Run the build_framework.py script from opencv/ios:

python build_framework.ph <some_directory_outside_of_opencv_tree>

I will let you know which one worked. My purpose is to build an OpenCV framework with JPG support :)

I am building an app that needs to write a jpg image on disk from OpenCV. implemented the OpenCV functionality as a static library.

Everything works fine if I run the library on my computer. The problem is when I run the code on XCode for iOS. I started by using the official OpenCV2.Framework, which, unfortunately does not have support for JPEG.

I cloned the code from git locally and tried playing around with the CMakeFiles.txt and the build script from python trying to add jpeg support to the framework, with no success.

Did anyone succeed in building an opencv2.framework for iOS with jpeg support? Or has any idea how should I do this? :)

Thanks!

I had the same problem. I solved it by setting in the XCode project Build Settings, for C++ Standard Library: libc++ (LLVM C++ standard library with C++ 11 support).

It is obvious from the errors that the problem is from the STD (standard C++ Library), so you should play around with the C++ Standard Library setting.

Hope it helps.
