Question

我写了一个使用pf_ring和asio的程序，

我的节目如下：

#include <boost/asio.hpp>
#include <pfring.h>

int main(void) {
    // ... 
    return 0;
}

我收到了错误：

In file included from /usr/local/include/pfring.h:46:0,
             from test.cpp:2:
/usr/include/linux/if.h:136:8: error: redefinition of 'struct ifmap'
/usr/include/net/if.h:112:8: error: previous definition of 'struct ifmap'
/usr/include/linux/if.h:170:8: error: redefinition of 'struct ifreq'
/usr/include/net/if.h:127:8: error: previous definition of 'struct ifreq'
/usr/include/linux/if.h:219:8: error: redefinition of 'struct ifconf'
/usr/include/net/if.h:177:8: error: previous definition of 'struct ifconf'

如何解决此问题？

Answer 1

这不是boost和pfringe之间的冲突。这里解释了这个问题：

/usr/include/linux/if.h:136:8: error: redefinition of 'struct ifmap'
/usr/include/net/if.h:112:8: error: previous definition of 'struct ifmap'

似乎问题是由Linux标头内的冲突引起的。首先，检查您是否拥有最新的Linux内核，Linux标头和pfringe。如果没有，请更新它们。如果失败，请检查您是否有任何旧标题。如果是这样，请删除它们。在Ubuntu中，这可以通过Computer Janitor应用程序完成。如果所有其他方法都失败了，请尝试卸载并重新安装pfringe。确保它是适合您操作系统的版本！

Answer 2

linux标头坏了。在最新的ubuntu 11.10版本中，最新内核没有旧标题，以下程序无法编译。当我需要来自两个标题的部分时非常烦人，例如来自net / if.h的if_nametoindex（）和来自linux / if_arp.h的ARPHRD_ETHER - 所以我所能做的就是将我需要的定义复制/粘贴到我的源代码中linux标题!!

#include <linux/if.h>
#include <net/if.h>

int main()
{
}

错误：

编辑：看起来这个错误已经在Linux内核包2.6.37-4.12中修复了：

https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/673073/comments/10

但由于某种原因，它不适用于我的基于Linux 3.0的系统。嗯...

我忘记了一个宏，添加到CFLAGS -DHAVE_PCAP。它已经解决了。谢谢大家
