DPDK样例编译

首先是从dpdk网站上下载了最新的LTS版本，dpdk-24.11.2.tar.xz解开后目录为dpdk-stable-24.11.2。我的环境是CentOS Linux release 8.5.2111。
然后进入examples/helloworld尝试编译

# make
Makefile:14: *** "no installation of DPDK found".  Stop.

于是进入上层源码根目录，尝试编译

[root@iecs dpdk-stable-24.11.2]# make
To build DPDK please use meson and ninja as described at
    https://core.dpdk.org/doc/quick-start/

进入quick-start网页查看，步骤简洁，照着来

# meson -Dexamples=all build
-bash: meson: command not found

那就先安装这些编译工具和依赖：

sudo yum install meson ninja-build numactl-devel

安装好后，再来编译

# meson -Dexamples=all build

meson工具版本比要求的低，得了，我下载上一个DPDK的LTS版本再来试试吧。
