C2059语法错误“字符串"? [英] C2059 syntax error 'string' ?

问题描述

extern "C" 
{
#endif
#include <stdint.h>
#include <limits.h>
#include "attributes.h"
}
#endif

我添加了 extern"C" {} 然后我得到 C2059字符串错误所以我尝试使用 #endif ，现在又出现了4个错误.

I added extern "C" { } Then i got the C2059 string error So i tried to use #endif, now i have another 4 errors.

Error   1   error C2059: syntax error : 'string'    d:\c-sharp\c++ 
compiling\consoleapplication7\consoleapplication7\libavutil\rational.h 31 1
ConsoleApplication7

如何解决此字符串错误?

How can i fix this string error ?

推荐答案

猜测一下，您是否包含C源文件中的这段代码?

At a guess, are you including this code from a C source file?

外部"C" {防护仅由C ++要求(或理解).您可以从C文件中省略它们，应将它们包括在C ++文件中，并应在头文件中使用 __ cplusplus ifdef保护它们.

extern "C" { guards are only required (or understood) by C++. You can omit them from a C file, should include them in a C++ file and should guard them with a __cplusplus ifdef in a header file.

#ifdef __cplusplus
extern "C" {
#endif
#include <stdint.h>
#include <limits.h>
#include "attributes.h"
#ifdef __cplusplus
}
#endif
