在 Linux Alpine 上安装 DPDK 时出错
Errors when installing DPDK on Linux Alpine
我正在尝试在 Alpine Linux 上安装 DPDK。我是运行高山Linux中的Docker。以下是我使用的步骤：
docker pull alpinedocker run -it alpine /bin/shwget https://git.dpdk.org/dpdk-stable/snapshot/dpdk-stable-16.11.8.tar.gztar -xzf dpdk-stable-16.11.8.tar.gzcd dpdk-stable-16.11.8apk add --no-cache make gcc libc-dev bsd-compat-headers linux-headers musl-devapk add numactl-dev --update-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ --allow-untrustedmake install T=x86_64-native-linuxapp-gcc
安装失败并出现以下错误和警告：

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？我能以某种方式使它可用吗？
更新 2
我尝试使用 this 而不是 musl-dev，但错误仍然存在。
然后按照建议，我在我的 Alpine Linux 上安装了 glibc 来使用它而不是 musl。按照步骤 。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
DPDK 似乎与 musl libc 不兼容，因此您可能很难一一修复错误。必须手动将预处理器定义和包含添加到 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(Ubuntu16.04)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__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;
};
注意缺少的 __cmsg_data 字段。
最后，经过一段时间和大量变通办法后，我设法在 Alpine Linux 上安装了 DPDK，即在 Docker 容器 运行 Alpine Linux.
这是我创建的 Docker 文件（内联注释）：

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？我能以某种方式使它可用吗？

我尝试使用 this 而不是 musl-dev，但错误仍然存在。
然后按照建议，我在我的 Alpine Linux 上安装了 glibc 来使用它而不是 musl。按照步骤
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
DPDK 似乎与 musl libc 不兼容，因此您可能很难一一修复错误。必须手动将预处理器定义和包含添加到 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(Ubuntu16.04)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__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;
};
注意缺少的 __cmsg_data 字段。
最后，经过一段时间和大量变通办法后，我设法在 Alpine Linux 上安装了 DPDK，即在 Docker 容器 运行 Alpine Linux.
这是我创建的 Docker 文件（内联注释）：
