Question

我对Cygwin配置有一点经验。我遵循了斯坦福大学课程中提供的书面设置教程;特别是教程2.不幸的是，在步骤3c的编译过程中，我遇到了一个错误，我无法执行make命令。

我收到以下错误：

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

[100%] Generating android-opencv

Answer 1

尝试这种方式：

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

如果需要进一步的信息，请告诉我。
