redeclaration of with no linkage 意思是“无链接的重新声明”，通常出现在 C 或 C++ 语言中。它表示在同一作用域内重复声明了一个变量或函数，但是这个变量或函数没有外部链接性，也就是说它只能在当前文件内使用，不能被其他文件引用。这种错误通常会导致编译错误或链接错误。

redeclaration of "rawtime" with no linkage

This error message typically occurs when you try to declare a variable with the same name multiple times in the same scope without any external linkage. In C, each variable must have a unique name within its scope. To resolve this issue, you should ensure that you only declare the variable "rawtime" once in the current scope. If you need to use the variable in different parts of your code, you can either declare it in separate scopes or use different names for each declaration. Here's an example to illustrate this: ```c #include <time.h> int main() { time_t rawtime; // Declare "rawtime" once // Rest of your code... { time_t rawtime; // Another declaration of "rawtime" in a different scope // Rest of your code... } return 0; } ``` By separating the declarations into different scopes, you can avoid redeclaring the variable without linkage error.

redeclaration of＂i＂with no linkage

As an AI language model, I can explain that a redeclaration of "i" with no linkage refers to creating a new variable or object called "i" within a specific scope that has no connection or access to any other "i" variables or objects outside of that scope. This means that any changes or modifications made to this specific "i" will not affect any other "i" variables or objects in other scopes.
