# C++类中报错:class "xxx" does not name a type ## 原因 1. 引用的类命名空间未包含 2. 引用的类头文件未包含 3. 包含了头文件,或者已经前置声明了,则说明所引用的类名写错。 4. 循环引用头文件 5. 类内修改了类成员 [类中报错
error: '[class name]' does not name a type 这个问题困扰了我好几个小时,真的很痛苦,所以记录一下。 我编译平台是Linux,编译命令如下: 代码语言:javascript 复制 g++-g-Wall-std=c++11-I/usr/local/mysql/include-I/usr/local/curl/include-o obj/tc_mysql.o-c tc_mysql.cpp 从命令中可以看出,我是...
declare class does not name a type 出现这个编译错误主要有四个可能原因,现总结如下: 1.引用的类命名空间未包含 2.引用的类头文件未包含 3.包含了头文件,或者已经前置声明了,则说明所引用的类名写错。 4.循环引用头文件 前置声明要素: 1.前置声明需要注意以上提到的四点 2.尽可能的采用前置声明(做到只有包...

(in 2 separate h files) and I've included them both inside one another. In my first h file, however, the dealers.h, I've made a pointer of type cars(which is the other class/h file) and when I try to compile, I get the error that cars does not name a type. Additionally, ...
member functions of a class template are not instantiated (i.e., written out by the compiler) until those member functions are used in the program. While most member functions require that B is complete, the class body alone does not (assuming the allocator type meets some basic requirements...
