如何在CentOS 7上安装Clang和LLVM 3.9

Question

我从https://copr-be.cloud.fedoraproject.org/results/alonid/llvm-3.9.0/epel-7-x86_64/00505197-clang-3.9.0/获取了rpm包, 用于Clang 3.9.

我正在通过命令安装rpm包

rpm -ivh clang-3.9.0-3.9.0-3.1.el7.centos.alonid.src.rpm

但是,当我这样做

rpm -ivh clang-3.9.0-3.9.0-3.1.el7.centos.alonid.x86_64.rpm

我收到以下错误:

我应该从哪里安装所有这些依赖项？

Answer 1

通过启用SCL存储库,您可以使用该llvm-toolset-7软件包在CentOS 7上安装Clang 4 .

$ sudo yum install centos-release-scl
$ sudo yum install llvm-toolset-7

启用llvm-toolset-7:

$ scl enable llvm-toolset-7 bash

你现在可以检查你的铿锵版:

$ clang --version

Answer 2

有一种更简单的方法来实现这一目标:

添加Alonid的回购/etc/yum.repos.d/epel.repo(假设你安装了epel repo)

echo "[alonid-llvm-3.9.0]
name=Copr repo for llvm-3.9.0 owned by alonid
baseurl=https://copr-be.cloud.fedoraproject.org/results/alonid/llvm-
3.9.0/epel-7-$basearch/
type=rpm-md
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://copr-be.cloud.fedoraproject.org/results/alonid/llvm-
3.9.0/pubkey.gpg
repo_gpgcheck=0
enabled=1
enabled_metadata=1" >> /etc/yum.repos.d/epel.repo

然后就是 sudo yum install clang-3.9.0

Answer 3

我是您提到的RPM存储库的作者。

从存储库的Copr主页上进行以下操作：

https://copr.fedorainfracloud.org/coprs/alonid/llvm-3.9.0/

如果您有任何疑问，可以从那里与我联系。谢谢！

只需打开您的链接并环顾四周，也可以上一级并找到所有必要的.rpm内容。以下顺序对我有用：

yum install compiler-rt-3.9.0-3.9.0-3.el7.centos.alonid.x86_64.rpm
yum install clang-3.9.0-libs-3.9.0-3.1.el7.centos.alonid.x86_64.rpm
yum install clang-3.9.0-3.9.0-3.1.el7.centos.alonid.x86_64.rpm
yum install llvm-3.9.0-libs-3.9.0-7.el7.centos.alonid.x86_64.rpm
yum install llvm-3.9.0-3.9.0-7.el7.centos.alonid.x86_64.rpm
yum install llvm-3.9.0-devel-3.9.0-7.el7.centos.alonid.x86_64.rpm

通过不使用yum install任何标志，Clang 和 LLVM 将安装到/opt/llvm-3.9.0：

$ ls -l /opt/llvm-3.9.0 
total 12
drwxr-xr-x 2 root root 4096 Jun  3 23:48 bin
drwxr-xr-x 3 root root 4096 Jun  3 23:23 include
drwxr-xr-x 3 root root 4096 Jun  3 23:27 lib64

另请注意，还有其他软件包，例如-devel, -static, -debuginfo。

有用的提示：如果不安装-devel软件包，您只能获得仅包含可执行文件和库之类的bin文件夹。如果您还想使用 LLVM/Clang 开发一些东西，您将需要相应的包。然后您还将获得带有标题的文件夹。lib64bin/clanglib64/libLLVM-3.9.0.so-develinclude/

顺便说一下，感谢这个仓库的维护者。很高兴开箱即用 LLVM 3.9。
