编译错误 [英] Compiler Error

问题描述

我在编译时收到此错误

输入结束时预期的非限定ID。


这是生成的代码块错误：


/ *代理unmountSource I / O * /

/ *方法unmountSource * /

void unmountSource（string theSource）

{

string source = theSource;

string unmount =" unmount";

string unmountFull = unmount + source;

string rmdir =" rmdir" ;;

string rmdirFull = rmdir + source;

system（unmountFull。 c_str（））;

system（rmdirFull.c_str（））;

}

/ * EMethod * /

/ * EProxy * /


编译器指向具有结束大括号的行。任何想法或

至少是错误的含义？

I am getting this error on compile "expected unqualified-id at end of
input".

Here is the block of code that generates the error:

/* Proxy unmountSource I/O */
/* Method unmountSource */
void unmountSource(string theSource)
{
string source = theSource;
string unmount = "unmount ";
string unmountFull = unmount + source;
string rmdir = "rmdir ";
string rmdirFull = rmdir + source;
system(unmountFull.c_str());
system(rmdirFull.c_str());
}
/* EMethod */
/* EProxy */

Compiler points to the line that has the end curly brace. Any ideas or
at least what the error means?

推荐答案

上面没有任何问题，假设字符串是别名

std :: string，所以错误发生在其他地方。


发布一个最小的可编译示例来证明你的问题。

Ian Collins。

There''s nothing wrong with the above, assuming string is an alias for
std::string, so the error is somewhere else.

Post a minimal compilable example that demonstrates your problem.

我可以看到两个不能编译的原因：

I can see two reasons why it won''t compile:

installGame(source, destination);
unmountSource(source);
cout << "Thank you for installing Train TrafficKing";
}

缺少返回。

Missing return.

/ * End Installer * /

}

/* End Installer */
}

缺少分号。
