亲爱的郭 歌@jdkboy，早上好，

我在openEuler 20.03 TLS everything 的安装还需要再更新一下安装库。

昨天在Ubuntu 20.4环境下，已经部署成功了 Clang 10.0.0.4.

近期我在关注Clang code static Anayzer.

如果能OpenEuler上升级到Clang 10.0.0.X，也是很不错的：）

在社区里，我找到了源代码包：clang-10.0.1.src.tar，没有能够编译成功。

这方面，还请教您，看看可不可以在移植到openEuler上，我们保持好一点的成绩。

从Mac OS 10.15来看，Apple的成绩是 Clang 11.X.

亟盼佳音：）

Shalom

主题: Re: Clang在openeuler编译，求助

时成阁，
你好，欢迎你使用openEuler并针对不足或者问题进行反馈。由于你反馈的是clang相关的问题，建议你找clang包的maintainer来回答你的问题。
为了节省时间，这次我把clang所属的Compiler sig组的maintainer抄送了一下，由他们来回答你的问题。 当然你也可以在clang的仓库中提issue来跟踪该问题。

建议：
1. 后续通过有问题或有疑惑的包的仓库中提issue来跟踪问题
2. 查找到包所在sig组，直接与该sig组maintainer进行沟通，可以快速解决问题。

希望 郭 歌@jdkboy 和 章 海剑@Haijian.Zhang 能够解决你的困惑。

clang的仓库：https://gitee.com/src-openeuler/clang
查看包所在sig组：https://gitee.com/openeuler/community/blob/master/sig/sigs.yaml
clang包是由compiler sig组看护，该sig组的信息：https://gitee.com/openeuler/community/tree/master/sig/Compiler
