OpenCV的鏈接，Xcode的

Question

我跟隨這名： http://sadeepj.blogspot.com.br/2012/03/installing-and-configuring-opencv-to.html

我有一個問題，編譯。但我已經修復它，修改2個文件...

現在我試圖運行該示例。

我收到此錯誤信息：

ld: library not found for -lopencv_core.2.4.6 clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已經遵循所有步驟。我甚至無法建立它。 請幫幫我。

[之前有人說這是一個重複的帖子，我知道它，這是原來的： C++ linker errors with OpenCV。 對不起。但是，我甚至不能發表評論說一句：/]

哇，終於解決了：

一些注意事項：

• 認識到，即使它正在尋找-l opencv_core.2.4.6，則 編譯器將得到正確的文件，如果它與其他 名稱正確添加，在這種情況下libopencv_core.2.4.dylib
• 我添加文件與項目>將文件添加到...，然後創建一個組並將文件拖入組中。這搞亂了鏈接項目>鏈接二進制與圖書館。所以我不得不通過將組中的文件拖到那個位置再次執行。

後論文的事情我已經在那裏我有兩個文件（核心和highgui）和4個錯誤的情況：

然後（感謝上帝和谷歌搜索的一些天），我得到這個：

Select your project, go to the Build Settings tab, filter by c++ standard library, and set this parameter to libstdc++ (GNU C++ standard library).

最後是在我的代碼環境再次陽光普照...
