將Android中的OpenCV庫導入到Eclipse後出錯

Question

在Eclipse中導入OpenCV庫後，我遇到了一個錯誤。我想我做了我應該做的，但也許我錯過了一些東西。樣本沒有錯誤，但是我的應用程序和OpenCV Library-2.4.10一樣。

這裏是我作爲輸出：

Answer 1

當我更改爲OpenCV Library 2.4.9而不是2.4.10後，錯誤消失了。在我用.mk文件創建jni文件夾後，我的應用程序出錯消失了。

Answer 2

從你的錯誤日誌，似乎路徑到你的Android NDK是錯誤的。您可以通過在Eclipse中指定Android NDK ndk-build的完整路徑來更正此問題。

首先，創建一個Build Variable。在Eclipse中，請轉至Window→Preferences→C/C++→Build→Build Variables。添加引用您的Android NDK ndk-build文件的完整路徑的新變量（您可以將其命名爲NDK_ROOT或任何您想要的）。

然後，單擊Apply並點擊Environment（Preferences - >C/C++ - >Build - >Environment），並添加您剛剛創建的變量。點擊Apply和OK。

之後，右鍵單擊您的Open-CV-Library，然後選擇Properties。導航到C/C++ Build - >Environment並在其中添加新創建的變量。點擊Apply和OK。

這應該工作。這就是我固定我的方式。

我希望這會有所幫助。

編輯

另一個修復程序可能是使用2.4.9版本，而不是2.4.10版本，因爲OpenCV的網站上目前的說明是針對2.4.9版本。
