在Linux上安装DPDK时出错

似乎DPDK与muslibc不兼容,所以您可能很难逐一修复错误。必须手动将预处理器定义和包含添加到CFLAGS似乎是一个不好的迹象。

最后一个错误是libc不兼容:

/dpdk-stable-16.11.8/lib/librte\u eal/linuxapp/eal/eal\u vfio\u mp\u sync.c:78:24:错误:“struct cmsghdr”没有名为“\u cmsg\u data”的成员memcpy(&(fd),(chdr).\u cmsg\u data,sizeof(fd))

在我的glibc(ubuntu16.04)中, cmsghdr 定义如下 bits/socket.h

/* Structure used for storage of ancillary data object information.  */
struct cmsghdr
  {
    size_t cmsg_len;            /* Length of data in cmsg_data plus length
                                   of cmsghdr structure.
                                   !! The type should be socklen_t but the
                                   definition of the kernel is incompatible
                                   with this.  */
    int cmsg_level;             /* Originating protocol.  */
    int cmsg_type;              /* Protocol specific type.  */
#if (!defined __STRICT_ANSI__ && __GNUC__ >= 2) || __STDC_VERSION__ >= 199901L
    __extension__ unsigned char __cmsg_data __flexarr; /* Ancillary data.  */
#endif
  };

请注意 __cmsg_data 最后。

cmsghdr公司 定义为:

struct cmsghdr {
        socklen_t cmsg_len;
        int __pad1;
        int cmsg_level;
        int cmsg_type;
};

__cmsg\U数据

最后,经过一段时间和大量的变通之后,我成功地在Alpine Linux上安装了DPDK,即在运行Alpine Linux的Docker容器上。

下面是我创建的Dockerfile(注释是内联的):
