我正在尝试使用Cygwin在Windows 7中编译此项目（https://github.com/alfchen/QoETrafficAnalyzer）。在Linux中我没有问题，但我在Windows中需要它。我按照此处包含的步骤安装了winpcap：help installing libpcap on cygwin。但是，我还有问题。我知道该项目使用arpa / inet.h并且在windows下你必须使用winsock2.h，但改变它并没有解决任何问题。现在我有以下错误。我希望有人可以帮助我。

在cygwin上，结构在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 */
};
上定义
其内容是：
from_json请注意，大部分cygwin内部都来自BSD，而不是来自Linux 在这种情况下，两个结构不匹配。
