使用 Cygwin 编译 OpenCV Android

Question

我在 Cygwin 配置方面有一点经验。我遵循了从斯坦福大学课程中获得的书面设置教程；特别是教程2。不幸的是，在步骤3c的编译过程中，我遇到了错误，无法执行make命令。

我收到以下错误：

cypat_000@Seattle ~/opencv/android/build
$ make

[100%] Generating android-opencv

Answer 1

试试这个方法：

Step 1: Add NDK path to your workspace. Also make sure you have c,c++ installed in your cygwin.
Step 2: Add JNI files: *.c and mk files to your project under jni directory. (I hope you know how to do this)
Step 3: Right click on project > Android Tools> Add Native Support to your project.
Step 4: Right click on project > Build > Build All
