Android ndk-build 编译错误 : ld: error: undefined symbol: std::__ndk1:

原因：

local.properties：ndk.dir 过期：

NDK was located by using ndk.dir property.
This method is deprecated and will be removed in a future release.
If you delete ndk.dir from local.properties and set android.ndkVersion to [22.1.7171670]
then NDK at
/Users/tmk/Library/Android/sdk/ndk/22.1.7171670 will be used.

解决：

1、取消 local.properties 中的 ndk.dir :

sdk.dir=/Users/tmk/Library/Android/sdk
#ndk.dir=/Users/tmk/Library/Android/sdk/ndk-bundle

2、确保已下载 ndk 和 cmake：
