我的项目使用 Android NDK，我在构建时遇到上述错误。

• 我安装了最新的 Java 版本、Android NDK 和 Android SDK
• 使用 Windows 8 和 Android Studio我在local.properties中添加了SDK和NDK

Answer 1

• 确保也添加 this 的内容存储库到 jni/arp-scan/arp-scan
• 还要确保添加 this 的内容存储库到 jni/iptables/custom-android-iptables

如果它不起作用，请将 ndkBuild 任务 commandLine 的标志更改为 -j1 以确保它不会并行构建:

commandLine "$ndkDir/ndk-build.cmd",
        'NDK_PROJECT_PATH=build',
        'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
        'NDK_APPLICATION_MK=src/main/jni/Application.mk',
        '-j1'

发布构建日志后编辑

发生此错误是因为在 makefile custom-android-iptabes/Android.mk 中有一个执行 mkdir -p/extensions/ 的脚本，即 基于 UNIX，而我假设您正在尝试从基于 DOS 的 Windows 进行构建。

您需要做的是将那些基于 UNIX 的脚本转换为基于 DOS 的脚本，例如，在本例中，mkdir\extensions\
