使用Cygwin編譯項目時出現錯誤

Question

我想使用Cygwin在Windows 7中編譯此項目（https://github.com/alfchen/QoETrafficAnalyzer）。在Linux中我沒有問題，但我需要在Windows中使用它。我按照以下步驟安裝winpcap：help installing libpcap on cygwin。但是，我仍然有問題。我知道這個項目使用arpa/inet.h，在windows下你必須使用winsock2.h，但是改變它並不能解決任何問題。現在我有以下錯誤。我希望有一個人可以幫助我。

Answer 1

在Cygwin的結構上/usr/include/netinet/tcp.h
其內容定義是：

struct tcphdr { 
     u_int16_t th_sport;    /* source port */ 
     u_int16_t th_dport;    /* destination port */ 
     tcp_seq th_seq;    /* sequence number */ 
     tcp_seq th_ack;    /* acknowledgement number */ 
#if __BYTE_ORDER == __LITTLE_ENDIAN 
     unsigned int th_x2:4,   /* (unused) */ 
         th_off:4;   /* data offset */ 
#endif 
#if __BYTE_ORDER == __BIG_ENDIAN 
     unsigned int th_off:4,   /* data offset */ 
         th_x2:4;   /* (unused) */ 
#endif 
     u_int8_t th_flags; 
#define TH_FIN 0x01 
#define TH_SYN 0x02 
#define TH_RST 0x04 
#define TH_PUSH 0x08 
#define TH_ACK 0x10 
#define TH_URG 0x20 
#define TH_FLAGS (TH_FIN|TH_SYN|TH_RST|TH_ACK|TH_URG) 

     u_int16_t th_win;     /* window */ 
     u_int16_t th_sum;     /* checksum */ 
     u_int16_t th_urp;     /* urgent pointer */ 
}; 

要知道，大多數cygwin的內部是從BSD而不是從Linux的 在這種情況下采取的兩個結構不匹配。
