我在 CentOS EL7， RockyLinux EL8 / EL9 打补丁都有失败提示啊，这样后面编译就过不去了。 不打补丁倒是能编译。 大家有遇到过吗？

其它 patch 没有异常。

已解决！ dpdk 版本选错了， 不是 dpdk-stable-20.11.10 ，应该是 dpdk-stable-20.11.1

注：EL7 可编译通过， EL8 EL9 不行。

看了下 dpdk-stable-20.11.1/doc/guides/linux_gsg/sys_reqs.rst 中的说明，提到

 Compatibility for recent distribution kernels will be kept, notably RHEL/CentOS 7.

所以，对于当前 dpvs 使用 dpdk-stable-20.11.1 的情况下，还是用 CentOS 7 来编译安装吧。

RockyLinux 8，确实可以编译通过，编辑 dpvs-1.9.6/src/Makefile 注释以下行

# CFLAGS += -Wall -Werror -Wstrict-prototypes -Wmissing-prototypes -mcmodel=medium
