Hi everyone, 1、gcc-12版本已经放入openEuler 22.09 EPOL仓里，openEuler 22.09每日构建版本地址为 http://121.36.84.172/dailybuild/openEuler-22.09/ 当前最新的每日构建版本为 http://121.36.84.172/dailybuild/openEuler-22.09/openeuler-2022-09-07-12-34-5... 可以从该网页下载ISO镜像进行系统安装。 2、yum源配置可以参考如下 ``` $ cat /etc/yum.repos.d/openEuler.repo [OS] name=OS baseurl=http://121.36.84.172/dailybuild/openEuler-22.09/openeuler-2022-09-07-12-34-5... enabled=1 gpgcheck=1 gpgkey=http://121.36.84.172/dailybuild/openEuler-22.09/openeuler-2022-09-07-12-34-5...
