  • 依赖及工具安装
apt-get install meson
apt-get install python3-pyelftools
apt-get install python3-pip
apt-get install pkg-config
apt-get install gcc
apt-get install vim
apt-get install net-tools
  • 安装DPDK并编译igb_uio驱动
wget https://fast.dpdk.org/rel/dpdk-22.07.tar.xz
tar xf dpdk-22.07.tar.xz
cd dpdk-22.07
-----------------------
meson build
# build文件夹中会新增build.ninja等文件用于安装各种库和可执行脚本
app          buildtools             config  drivers   lib         meson-logs     rte_build_config.h
build.ninja  compile_commands.json  doc     examples  meson-info  meson-private  usertools
-----------------------
cd build
ninja
ninja install
----------------
root@bruce:/home/bruce/dpdk-22.07/build# ls /usr/local/bin/
dpdk-devbind.py    dpdk-pmdinfo.py    dpdk-test        dpdk-test-cmdline        dpdk-test-eventdev   dpdk-test-gpudev    dpdk-test-regex
dpdk-hugepages.py  dpdk-proc-info     dpdk-test-acl    dpdk-test-compress-perf  dpdk-test-fib        dpdk-test-pipeline  dpdk-test-sad
dpdk-pdump         dpdk-telemetry.py  dpdk-test-bbdev  dpdk-test-crypto-perf    dpdk-test-flow-perf  dpdk-testpmd

# 库和脚本及可执行程序保存路径如下：
/usr/local/lib/x86_64-linux-gnu/
/usr/local/bin/
# 卸载请执行 ninja uninstall 命令即可

注：(可选操作)

如果是在虚拟机中进行编译，可执行如下操作进行快速编译，以下操作应在执行meson build命令之前。

vi drivers/meson.build         # subdirs只保留bus mempool net
vi drivers/bus/meson.build     # drivers只保留pci vdev
vi drivers/mempool/meson.build # drivers只保留ring stack
vi drivers/net/meson.build     # drivers只保留e1000

然后执行meson build命令，大致会输出如下内容则表示正常：

Message: 
===============
Drivers Enabled
===============

bus:
        pci, vdev, 
mempool:
        ring, stack,
