編譯XBMC適用於iOS誤差之前令牌丟失的二進制運算符 「（」

Question

我編譯XBMC適用於iOS具有以下配置：

$ CD $ HOME/XBMC $ CD工具/取決於 $ ./bootstrap $的./configure --host =手臂，蘋果達爾文 $使

我得到以下輸出：

我發現dispatch.h 49線在此：

#include <dispatch/base.h> 

dns_sd.h 140線在這種：

#if _DNS_SD_LIBDISPATCH 
#include <dispatch/dispatch.h> 
#endif 

base.h 103線在這種：

#if defined(__has_feature) && __has_feature(objc_fixed_enum) 
#define DISPATCH_ENUM(name, type, ...) \  typedef enum : type { __VA_ARGS__ } name##_t 
#else 
#define DISPATCH_ENUM(name, type, ...) \  enum { __VA_ARGS__ }; typedef type name##_t 
#endif 

base.h 44線在此：

#define DISPATCH_SENTINEL __attribute__((__sentinel__)) 

dnssd.c這行62行：

#include <dns_sd.h> 
#define DNSSD_STDCALL 

我不明白爲什麼它在這裏抱怨二元運算符，這是XBMC的錯誤嗎？

我是新來的鐺，但我設法解決這個問題。在文件的頂部

dnssd.c 

並粘貼下面的代碼：打開文件

#ifndef __has_feature   // Optional of course. 
    #define __has_feature(x) 0 // Compatibility with non-clang compilers. 
#endif 
#ifndef __has_extension 
    #define __has_extension __has_feature // Compatibility with pre-3.0 compilers. 
#endif 

這將改善與一些編譯器爲Clang Language documentation兼容性。
