With latest open cv framework i am unable to compile code on IOS device. i am facing following error.
Undefined symbols for architecture arm64: "_png_init_filter_functions_neon", referenced from: _png_read_filter_row in opencv2(pngrutil.o) ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
Same app is able to compile for simulator but not for ios devices. Can any one tell me why i am facing this problem. Thanks in advance.
I had fixed this problem.The core of this problem is that we recompile some content in libpng,maybe it exits in other ios framework.Then it makes a conflict.Opncv 3.1 has 3rdparty in it's code.What you should do is find the lines 117-121 in libpng's pngpriv.h.Then just follow Iphone - device - linker error.
