有關Xcode中OpenCV的鏈接錯誤

Question

我正在使用XCode4和OpenCV 2.3。 我編譯了一個OpenCV的副本。這裏是.a的信息：

libopencv_core.a: Mach-O universal binary with 3 architectures 
libopencv_core.a (for architecture armv7): current ar archive random library 
libopencv_core.a (for architecture armv6): current ar archive random library 
libopencv_core.a (for architecture i386): current ar archive random library 

我把它拖到Frameworks floder中，並設置庫搜索的正確路徑。 但是當我編譯時，它發生了這樣的錯誤：

看來，在OpenCV庫中使用的STL沒有鏈接在.a文件中。 如何解決它？

謝謝，鞠躬。符號（S）沒有發現建築的ARMv7 collect2：用於建築的ARMv7

BTW：當我設置的文件名。毫米，鏈接器報告內部編譯器錯誤。總線錯誤。

Answer 1

我得到答案。

OpenCV中的MIN宏與Xcode中預定義的MIN衝突。

將.m文件重命名爲.mm，並將所有MIN函數更改爲新名稱，例如OpenCV頭文件中的CV_MIN。

檢查。

Answer 2

必應，你是正確的關於OpenCV的MIN（和MAX）宏。我必須重新命名它們，可能從2.0版開始:)

但是，沒有必要將所有.m文件重命名爲.mm文件，因爲Xcode默認處理它們的方式不同 - 是Objective-C++文件 - 想。

正如David所指出的那樣，最好鏈接std C++庫。

Answer 3

另一件值得一提的事情，至少在xcode 4.5中，是你必須在你的目標設置中將你的C++標準庫改爲'libstdC++'才能讓openCV編譯。

Answer 4

刪除了iOS 4.3的支持和使用「的libC++」也可能有助於

Answer 5

，您可以通過使用C++標準庫設置鏈接。 「構建階段 - >鏈接二進制與圖書館」
