How to run this code?

usr/local/include/opencv2/core/cvstd.hpp:556:5: error: ‘cv::String::String(int)’ is private
String(int); // disabled and invalid. Catch invalid usages like, commandLineParser.has(0) problem

I am in the same condition, have you solved it?

If you run this code on ubuntu , try "g++ -o mtcnn_opencv mtcnn_opencv.cpp -std=c++11", it seems like that the error is caused by C++11 new feature.

@graycrown @mwy691222563 Please help me to run this code. I use cmake and make way to generate it, but errors ocured:

/mtcnn_opencv.cpp.o：在函数‘MTCNN::MTCNN(std::__cxx11::basic_string<char, std::char_traits, std::allocator > const&)’中：
mtcnn_opencv.cpp:(.text+0xae)：对‘cv::dnn::experimental_dnn_v4::Net::Net()’未定义的引用
mtcnn_opencv.cpp:(.text+0xc1)：对‘cv::dnn::experimental_dnn_v4::Net::Net()’未定义的引用
mtcnn_opencv.cpp:(.text+0xd4)：对‘cv::dnn::experimental_dnn_v4::Net::Net()’未定义的引用
mtcnn_opencv.cpp:(.text+0x174)：对‘cv::dnn::experimental_dnn_v4::readNetFromCaffe(cv::String const&, cv::String const&)’未定义的引用
mtcnn_opencv.cpp:(.text+0x19c)：对‘cv::dnn::experimental_dnn_v4::Net::~Net()’未定义的引用
....

I dont know where the wrong is.
If it's the path problem, I did setted and included the opencv path.

[mwy691222563]

it seems some libs should be linked.

@mwy691222563 yeah I found some opencv libs should be linked in CMakeLists file. thx~~

It's the same quesion @graycrown how do you solve
