error: unknown type name 'Evaluator'

[ckeys]

Hi All,

根据guideline http://www.paddlepaddle.org/docs/develop/documentation/zh/mobile/cross_compiling_for_android_cn.html
我尝试在mac上编译armeabi-v7a，Android API 21的PaddlePaddle库
使用命令行：

$ docker run -it --rm -v $PWD:/paddle -e "ANDROID_ABI=armeabi-v7a" -e "ANDROID_API=21" username/paddle-android:dev

但是出现如下错误

@ckeys 最近针对Mobile做了一些代码的裁剪工作，把一些Mobile端用不到的代码隔离出去了，但是单测里面没有完全隔离。Docker的编译，默认是要编译单测的。
暂时的解决方案：您可以在paddle/script/docker/build_android.sh的CMake命令中设置-DWITH_TESTING=OFF，暂时不编译单测。
我们会尽快fix这个问题~

非常感谢~
