错误：任务'ndkBuild'的执行失败。 ＆GT;进程'命令'Android \ sdk \ ndk-bundle / ndk-build.cmd''以非零退出值2结束

Question

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

ndk.dir=C\:\\Users\\Jang\\AppData\\Local\\Android\\sdk\\ndk-bundle
sdk.dir=C\:\\Users\\Jang\\AppData\\Local\\Android\\sdk

这是我的build.gradle：

Answer 1

• 确保将this存储库的内容添加到Components
• 还要确保将this存储库的内容添加到jni/arp-scan/arp-scan

如果它不起作用，请将 ndkBuild 任务jni/iptables/custom-android-iptables的标志更改为-j1，以确保它不是并行构建的：

commandLine

发布构建日志后编辑

发生此错误是因为在makefile 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' 中有一个执行custom-android-iptabes/Android.mk且 UNIX 的脚本，而我认为，您正在尝试从Windows构建谁是 DOS 。

您需要做的是将基于UNIX的脚本转换为基于DOS的脚本，例如，在这种情况下，mkdir -p /extensions/

Answer 2

将环境变量 NDK_TOOLCHAIN_VERSION 设置为 4.9 可以解决问题
