在 Mac OS Maverick 上，我安装了 OpenCVbrew install opencv.
我创建了一个简单的程序（复制自本教程 http://blogs.wcode.org/2014/10/howto-install-build-and-use-opencv-macosx-10-10/）。编译工作正常，但运行可执行文件时出现以下错误：
dyld: Library not loaded: /usr/local/lib/libpng16.16.dylib
Referenced from: /usr/local/lib/libopencv_highgui.2.4.dylib
Reason: Incompatible library version: libopencv_highgui.2.4.dylib requires version 33.0.0 or later, but libpng16.16.dylib provides version 32.0.0
Trace/BPT trap: 5
我查了一下libpng已通过正确安装brew install libpng并跑了一个brew upgrade确保一切都是最新的。
Running locate libpng16.dylib返回：
/Applications/GIMP.app/Contents/Resources/lib/libpng16.16.dylib
/usr/local/Cellar/libpng/1.6.10/lib/libpng16.16.dylib
/usr/local/Cellar/libpng/1.6.12/lib/libpng16.16.dylib
/usr/local/Cellar/libpng/1.6.13/lib/libpng16.16.dylib
/usr/local/Cellar/libpng/1.6.15/lib/libpng16.16.dylib
/usr/local/lib/libpng16.16.dylib
任何想法？
最好的解决方案是完全卸载 libpng 并重新安装：
$ sudo brew uninstall libpng
$ sudo rm '/usr/local/bin/libpng-config'
$ for i in `brew link --overwrite --dry-run libpng`; do sudo rm $i; done
$ sudo brew install libpng
如果需要安装opencv：
$ sudo brew tap homebrew/science
$ sudo brew install opencv
