出现这个错误一般是操作数的类型与操作符所要求的不匹配,比如(string类型需要<string>头文件): 1.使用系统的类时出错,或者尝试对不正确的类型进行运算符操作 比如: string a="abc"; cout<<3+a; //将一个整数与一个string类型的变量相加,这是+运算不允许的 2.在使用自己定义的类时,尝试使用系统默认的运算符...

在这种结构中,CMakeLists.txt 文件应该存在于以下目录中:顶级项目目录、src、doc、extern 和test。主列表文件不应该声明任何自身的构建步骤,而是应该使用 add_subdirectory() 命令来执行嵌套目录中的所有列表文件。如果有需要,这些还可以将这项工作委托给更深层次的目录。 注意 一些开发者建议将可执行文件与库分开,创...
