QT opencv darknet异常

Question

debug到载入网格的时候就异常退出了，该怎么知道错误原因呢？加try catch也没输出任何东西。QT中你们都是这样调试的吗？只能找到某一行，不知道具体出错原因？

【说明】：

（1）代码没有问题，相同代码在VS2019下运行正常。

（2）环境没有问题，相同环境，且QT正常配置了参数，编译前无语法错误，在dnn.hpp中有三个函数，见尾部引用。。。

（3）关于路径：三个训练文件都放在了，工程的build-MeDetection-Desktop_x86_windows_msvc2019_pe_64bit-Debug 文件夹下了，出错代码的上方代码为：

    std::string classesFile = "me.names";
    std::ifstream classNamesFile(classesFile.c_str());
    if (classNamesFile.is_open())
    {
        std::string className = "";
        while (std::getline(classNamesFile, className))
            classes.push_back(className);
    }
    else {
        std::cout << "can not open classNamesFile" << std::endl;
    }

上面的代码并没有输出“can not open classNamesFile”,说明me.names的路径是正确的，同理，另两个文件的路径应该也没有问题，但是cv::dnn::readNetFromDarknet(modelConfiguration, modelWeights)这句就是通过不了，还不能提示具体的原因怎么办？？？

-----------------------------谢谢

这种引用静态库的程序，需要严格匹配c++编译器的版本，否则就会各种报错，尽管可以编译。
