提示:error: cannot pass objects of non-trivially-copyable type ‘std::string’ 2、原因或排查方式 语法: const char *c_str(); c_str()函数返回一个指向正规C字符串的指针, 内容与本string串相同. 为了与C兼容,在C中没有string类型,故必须通过string类对象的成员函数c_str()把string对象转换成C中的字...
遇到"error: cannot pass objects of non-trivially-copyable type ‘std::string’"错误时,通常出现在试图将 `std::string` 类型对象作为普通类型参数传递给函数或作为函数返回值使用的情景。问题来源主要是由于C++语言中`std::string`类型的对象不是可简单复制的类型,因此不能被直接传递给不需要完整...

原因是C里面没有string类型 解决办法 stringstr; str.c_str() 1. 2. 具体例子如下: #include <iostream> usingnamespacestd; intmain() { stringstr; cin>>str;// 输入字符串时,遇到空格或者回车就会停止 cout<<str<<endl;// 输出字符串时,遇到空格或者回车不会停止,遇到'\0'时停止 ...
2. 对opencv及opencv_contrib 进行cMake时出现 "project invalid" 、 "CMake Error at cmake/OpenCVModule.cmake:370 (_glob_locations):" 以及 所需组件无法下载(例如 "FFMPEG: Download failed" )等错误。 3. 新opencv编译程序报错LNK1104 cannot open file 'opencv_aruco347.lib'。

std::cout<<"yes"<<std::endl;//return false;};intmain() { Test*t =newTest;boolr = t->yes(); std::cout<<"yes->"<< r <<std::endl;return0; } 用g++编译得到警告但是通过了,并且执行得到正确预期(但是值为啥是64?没有找到原因!)。
The following example shows a function that assumes that any exception that might be thrown is either aWin32Exceptionor an exception type derived fromstd::exception. The function catches any exception of these types and propagates the error information as a Win32 error code to the caller. ...
