centos7 dpdk环境搭建
- 下载源码
dpdk官网： https://www.dpdk.org/
DPDK Core->Download->选择需要的版本进行源码下载
- 安装依赖
# yum install make
# yum install gcc
# yum install numactl-devel*x86_64
# yum install kernel-devel
# modprobe uio
等等。
具体参考DPDK->Documentation->LINUX USER GUIDE->Getting Started Guide for Linux->System Requirements章节
- 编译
# tar xJf dpdk-.tar.xz
# cd dpdk-
编辑目标平台配置文件，格式为ARCH-MACHINE-EXECENV-TOOLCHAIN
# cp config/defconfig_x86_64-native-linuxapp-gcc config/defconfig_x86_64-snb-linuxapp-gcc
# vi config/defconfig_x86_64-snb-linuxapp-gcc
修改
CONFIG_RTE_MACHINE="snb"
# make install T=x86_64-snb-linuxapp-gcc
在源码目录下生成的x86_64-snb-linuxapp-gcc文件夹就是目标平台需要的dpdk环境
- 库开发
1. 添加库选项
# vi config/defconfig_x86_64-snb-linuxapp-gcc
添加
CONFIG_RTE_LIBRTE_TEST=y
2. 在lib目录下创建test工程代码以及Makefile
3. 添加库路径
# vi lib/Makefile
添加
DIRS-$(CONFIG_RTE_LIBRTE_TEST) += librte_test
4. 添加库链接
# vi mk/rte.app.mk
添加
_LDLIBS-$(CONFIG_RTE_LIBRTE_TEST) += -lrte_test
5. 清空旧环境数据
# rm x86_64-snb-linuxapp-gcc/ -rf
6. 编译
# make install T=x86_64-snb-linuxapp-gcc
7. 确认
# ls x86_64-snb-linuxapp-gcc/lib/librte_test.a
