Question

我搜遍了整个地方，找不到这个经常重新发生错误的答案。它真的开始惹恼我了。

无论如何，这是我得到的错误：

74:1: error: expected unqualified-id before ‘{’ token
81:21: error: ‘chat’ has not been declared
81:5: warning: second argument of ‘int main(int, int**)’ should be ‘char **’ [-Wmain]
118:10: error: ‘clean_up’ was not declared in this scope

我不妨发布整个程序以避免混淆。可能我注意到我正在按照教程进行操作但仍然遇到这些错误。该教程没有提供任何帮助！

#include "SDL/SDL.h"

任何帮助？

Answer 1

bool init(); // <--- you have an extra semicolon here
{ //this is line 43 in which the compiler is pointing at.

Answer 2

对于mee，看起来你在第42行意外插入了一个分号：

bool init();
{ //this is line 43 in which the compiler is pointing at.

试试这样：

bool init()
{ //this is line 43 in which the compiler is pointing at.

Answer 3

删除分号bool init();

在'{'标记之前预期的非限定id
