由于可访问性错误我无法使用 Xorg-server 1.13 到 1.15。我看到 CentOS 7 使用1.15.0。有没有办法在 CentOS 7 中使用更高版本的 Xorg-server？

软呢帽23有 Xorg-server 1.18.0，考虑到 Fedora 几乎是以后进入 RHEL 和 CentOS 的测试平台，有没有办法在 CentOS 中使用 Fedora 的 Xorg-server？

答案1

如果 rhel 和 fedora 之间的库依赖关系没有改变（机会很小），您可以使用 fedora 软件包，因为 RedHat 7 是基于 Fedora 19 的。

您可以尝试在 RHEL7 机器上从 fedoras srpm 重建必要的软件包。

所以我想知道是否可以为 el7 重新编译最新的 xorg （我没有尝试安装 fedora 软件包，因为我怀疑这几乎是一个死胡同）。

令我惊讶的是，我成功做到了。我只将生成的 rpm 安装在 docker 容器中，没有进行任何测试或启动服务器来查看它是否有效。

编辑2：

添加了命令来构建所有 libX 包。我无法重建台面（工作量太大，因为它需要更新的 clang 包和其他一些东西）

这是我用来进行构建的脚本。一切都是在 docker 容器中完成的：

docker run --rm -it _your_container_ bash

#!/bin/bash

rm -f /etc/yum.repos.d/*

# I built packages from rawhide, you should use fedora23 probably
# we need yum-plugin-priorities and priority=1 for srpm repo
# if you use oracle linux, remove centos repo
#  and add oracles ol_latest and ol_optional

答案2

我很高兴地报告这一点CentOS 7-1511 使用 Xorg-server 1.17.2，它不会遭受可访问性错误。因此该版本无需修补即可使用。
