Question

我在fedora core 5中运行了一个程序（链接是 - http://www.security-freak.net/raw-sockets/sniffer_eth_ip_tcp.c）。在编译时，我收到以下错误：

[root@localhost ~]# gcc sniffer_eth_ip_tcp.c
    In file included from sniffer_eth_ip_tcp.c:12: /usr/include/linux/ip.h:97: error: expected specifier-qualifier-list before ‘uint8_t’
    In file included from /usr/include/linux/tcp.h:21,
                 from sniffer_eth_ip_tcp.c:13:
    /usr/include/asm/byteorder.h:6:2: warning: #warning using private kernel header; include   <endian.h> instead!
    sniffer_eth_ip_tcp.c: In function ‘ParseIpHeader’:
    sniffer_eth_ip_tcp.c:147: error: ‘struct iphdr’ has no member named ‘daddr’
    sniffer_eth_ip_tcp.c:148: error: ‘struct iphdr’ has no member named ‘saddr’
    sniffer_eth_ip_tcp.c: In function ‘ParseTcpHeader’:
    sniffer_eth_ip_tcp.c:185: error: ‘struct iphdr’ has no member named ‘protocol’
    sniffer_eth_ip_tcp.c:187: error: ‘struct iphdr’ has no member named ‘ihl’

但是，相应头文件中的struct iphdr包含上面提到的数据成员。任何人都可以帮忙..

Answer 1

获得该错误的唯一方法是，如果您的程序所指的iphdr不包含这些数据成员。因此，搜索所有包含，检查dup等等（同样，您可以通过预编译运行源代码并查找已包含的所有内容，通常会提供您的答案）

在源上运行cpp以找出包含哪些头文件（以哪种顺序）。如果您在正确信息之前包含错误信息的标题，则会出现问题。实质上，只包括编译程序所需的头文件

如何解决'struct iphdr'之类的错误没有名为'daddr'的成员
