New subject: 答复: 答复: 答复: Clang在openeuler编译，求助

      你好，

目前openEuler的主干以及20.03版本都已经升级到10.0.1了，但是补丁还没有发布，待补丁发布后，预期可以在 http://repo.openeuler.org/openEuler-20.03-LTS/update/aarch64/Packages/ 下面看到供升级的包（也有可能有别的提供方式，比如在sp版本中提供，这个要看release-management SIG的安排）

对于将llvm升级到11.0.0版本，我认为现在还不是最好的时机，因为11.0.0版本社区实际上还没有发布最终正式版本，目前只有rc版本，请见 http://llvm.org/，我们会在社区发布final版本的时候升级至最新版本

我们致力于为openEuler社区提供【最具竞争力的】【稳定版本】，对于一些包我们会保持活跃的开发态，和上游社区的开发状态保持一致，但llvm目前还不在此列

祝好

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

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<mailto: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

尊敬的zhiqiang总，
我是openEuler的爱好者，最近在看Clang编译器方面的文章，尝试了一下在openEuler上使用Clang. 在标准版openEuler-20.03-LTS-x86_64-dvd中，没有发现默认安装库。后来我又扫描openEuler-20.03-LTS-everything-x86_64-dvd，有版本7.0的Clang, 但是安装后，在shell中，任然没有Clang可用入口。
在社区里面，发现了您的联系信息，https://gitee.com/src-openeuler/mariadb-connector-c/commit/3494a96c5d0d92acd49d89bb1ce2130e418bbf48，不知道可不可以向您求助，如何在openeuler安装使用Clang?
我看在CentOS 8中，默认安装库是Clang 9.0.X
在Mac OS 10.15中，默认安装库是Clang 11.0.X
在CLang/llvm开源站点，下载最新版是10.0.X。 http://clang.llvm.org/get_started.html
如果方便，请回信。
亟盼回复。
