我正在尝试安装DPDK在 Alpine Linux 上。我在 Docker 中运行 Alpine Linux。以下是我正在使用的步骤:
-
docker pull alpine -
docker run -it alpine /bin/sh -
wget https://git.dpdk.org/dpdk-stable/snapshot/dpdk-stable-16.11.8.tar.gz -
tar -xzf dpdk-stable-16.11.8.tar.gz -
cd dpdk-stable-16.11.8 -
apk add --no-cache make gcc libc-dev bsd-compat-headers linux-headers musl-dev -
apk add numactl-dev --update-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ --allow-untrusted -
make install T=x86_64-native-linuxapp-gcc
安装失败并出现以下错误和警告:

我修复了一些错误，但现在出现了新的错误。 以下是更新的步骤:
-
docker pull alpine -
docker run -it alpine /bin/sh -
wget https://git.dpdk.org/dpdk-stable/snapshot/dpdk-stable-16.11.8.tar.gz -
tar -xzf dpdk-stable-16.11.8.tar.gz -
cd dpdk-stable-16.11.8 -
apk add --no-cache make gcc libc-dev bsd-compat-headers linux-headers musl-dev -
apk add numactl-dev --update-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ --allow-untrusted - 添加
#include <fcntl.h>至lib/librte_eal/common/include/rte_common.h - 添加
CFLAGS += -D_GNU_SOURCE至lib/librte_eal/linuxapp/eal/Makefile -
make install T=x86_64-native-linuxapp-gcc
安装现在失败并出现以下错误:

如果你看一下/usr/include/x86_64-linux-gnu/bits/socket.h , struct cmsghdr定义如下:
/* 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 __glibc_c99_flexarr_available
__extension__ unsigned char __cmsg_data __flexarr; /* Ancillary data. */
#endif
};
什么是__glibc_c99_flexarr_available ？我可以以某种方式使其可用吗？
更新2
我尝试使用 this而不是musl-dev但错误仍然相同。
然后按照建议，我安装了 glibc在我的 Alpine Linux 上使用它而不是 musl 。按照步骤 here 。现在我收到这样的错误:
In file included from /dpdk-stable-16.11.8/lib/librte_eal/linuxapp/eal/eal.c:48:0:
/usr/include/limits.h:124:26: fatal error: limits.h: No such file or directory
# include_next
请您参考如下方法:
DPDK 似乎与 musl libc 不兼容，因此您可能很难一一修复错误。必须手动添加预处理器定义并包含到 CFLAGS 似乎是一个坏兆头。
最后一个错误是这样的 libc 不兼容:
/dpdk-stable-16.11.8/lib/librte_eal/linuxapp/eal/eal_vfio_mp_sync.c:78:24: error: 'struct cmsghdr' has no member named '__cmsg_data' memcpy(&(fd), (chdr).__cmsg_data, sizeof(fd))
在我的 glibc (Ubuntu 16.04) 中，cmsghdr 在 bits/socket.h 中定义如下:
/* 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
};
注意最后的__cmsg_data的定义。
在 musl 中，cmsghdr 定义为:
struct cmsghdr {
socklen_t cmsg_len;
int __pad1;
int cmsg_level;
int cmsg_type;
};
请注意缺少的 __cmsg_data 字段。
