在android平台编译并使用dlib人脸识别库

编译dlib

新建项目，选择c++支持，在CMakeLists.txt中添加dlib：

include(src/main/cpp/dlib/cmake)  

再链接dlib库

target_link_libraries( # Specifies the target library.                         native-lib                         dlib                         # Links the target library to the log library                         # included in the NDK.                         ${log-lib} )

遇到问题

1.std::to_string
2. error :no member named ‘round’ in namespace ‘std’; did you mean simply ‘round’?
3. error: no type named ‘exception_ptr’ in namespace ‘std’; did you mean ‘exception’?

经验总结

1.将dlib移植到android应该是有很多人做过的，先不急着上手编译，而应该广泛搜索解决方案。
2.cmake很实用，早点系统学习。
