I used the compiled version of OpenCV for armv7s that can be found here :

https://github.com/hammer498

I use the grabcut function, which works, as some others function

but when i use merge or split method, i got error during compilation

Undefined symbols for architecture armv7s:
"cv::merge(std::vector > const&, cv::_OutputArray const&)", referenced from: -[GrabcutVC startGrabcut] in GrabcutVC.o "cv::split(cv::Mat const&, std::vector >&)", referenced from: -[GrabcutVC startGrabcut] in GrabcutVC.o ld: symbol(s) not found for architecture armv7s

Did i miss something ?

This post is a bit related to

OpenCV.Framework does not compile for the armv7s architecture

I wanted to post a comment but my reputation is too low

Hammer, i hope you can see this post :)

Thanks

I had this same problem and fixed it by changing "C++ Standard Library" to libc++:

CLANG_CXX_LIBRARY = libc++

Previously I had it set to Compiler Default.

I don't know what would be causing your problem. My solution is now outdated though because opencv 2.4.3 comes with support for armv7s. I would recommend downloading and using it.
