我已经下载了openCV库。现在，当我尝试运行示例faceDetection应用程序时，它显示以下错误：

但预编译的facedetection.apk运行没有任何问题。所以当我从示例应用程序运行它时会出错？请帮帮我..我正在使用ubuntu os。

Answer 1

Solved ..我已经将环境变量路径设置为ndk ..并使用ln命令建立了链接，重建后问题解决了。

Answer 2

如果你使用ubuntu，

项目右键单击 - ＆gt;属性 - ＆gt; c / c ++ build - ＆gt;构建命令

如果这是ndk-build.cmd，你必须修复＆＃34;你的ndk路径/ ndk-build＆＃34;
