Linux 9的repo for OVS build

 源码中自带RPM包spec文件

cd /root/rpmbuild/SOURCES/openvswitch-2.17.7/rhel

rpmbuild -bb openvswitch.spec

## 按提示解决，不好解决的依赖可以试试下面的repo 方法 

error: File /root/rpmbuild/SOURCES/openvswitch-2.17.7.tar.gz: No such file or directory

 rpmbuild -bb openvswitch.spec          
error: Failed build dependencies:
        checkpolicy is needed by openvswitch-2.17.7-1.el7.x86_64
        selinux-policy-devel is needed by openvswitch-2.17.7-1.el7.x86_64
        python3-sphinx is needed by openvswitch-2.17.7-1.el7.x86_64
        unbound-devel is needed by openvswitch-2.17.7-1.el7.x86_64
        libunwind-devel is needed by openvswitch-2.17.7-1.el7.x86_64

1. 自己build openvswitch rpm包解决依赖问题 

. centos9/Rocky9 redhat 9 的repo 可用 

安装 libunwind-devel in Rocky 9  for building  openvswith 

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

yum -y install libunwind-devel

 Rocky  9 unbound-devel的安装方法

dnf --enablerepo=crb install unbound-devel

dnf --enablerepo=crb install python3-sphinx-latex

 python3-sphinx 安装in centos9

安装iso中的版本

dnf install centos-release-nfv-openvswitch

dnf search openvswitch
