将适用于 Android 的 OpenCV 库导入 Eclipse 后出错

Question

在 Eclipse 中导入 OpenCV 库后，我遇到了一个错误。我想我做了我应该做的，但也许我错过了一些东西。示例没有错误，但我的应用程序和 OpenCV Library-2.4.10 都有错误。

这是我的输出：

Answer 1

在我更改为 OpenCV Library 2.4.9 而不是 2.4.10 后，错误消失了。在我使用 .mk 文件创建 jni 文件夹后，我的应用程序的错误消失了。

Answer 2

从您的错误日志来看，您的 Android NDK 的路径似乎是错误的。您可以通过在 Eclipse 中指定 Android NDK ndk-build 的完整路径来纠正此问题。

首先，创建一个Build Variable。在 Eclipse 中，转到 Window -> Preferences -> C/C++ -> Build -> Build Variables。添加一个引用 Android NDK ndk-build 文件的完整路径的新变量（您可以将其命名为 NDK_ROOT 或任何您想要的名称）。

然后，单击Apply 并单击Environment（Preferences -> C/C++ -> Build -> Environment）并添加刚刚创建的变量。点击Apply和OK。

之后，右键单击您的 Open-CV-Library，然后选择 Properties。导航到C/C++ Build -> Environment 并在那里添加新创建的变量。点击Apply和OK。

应该可以。我就是这样修的。

我希望这会有所帮助。

另一个解决方法可能是使用 2.4.9 版而不是 2.4.10 版，因为 OpenCV 网站上的当前说明适用于 2.4.9 版。
