如何在CentOS 7上安裝Clang和LLVM 3.9

Question

對於Clang 3.9，我已經從 https://copr-be.cloud.fedoraproject.org/results/alonid/llvm-3.9.0/epel-7-x86_64/00505197-clang-3.9.0/中得到rpm包。

我被命令

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

安裝RPM軟件包，但，當我做

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

我收到以下錯誤：

我應該在哪裏安裝所有這些依賴關係？

Answer 1

只要打開your link環顧四周，也可以走高一級，找到所有必要的.rpm's。下面的序列爲我工作：

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 

通過只是在做yum install沒有鏘和LLVM將被安裝到/opt/llvm-3.9.0任何標誌：

$ 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 

還要注意，還有其他的包，比如-devel，-static，-debuginfo 。

有用的提示：如果不安裝-devel包，你只能得到bin和lib64文件夾，其中只喜歡bin/clang的可執行文件和庫像lib64/libLLVM-3.9.0.so所在。如果你還想用LLVM/Clang開發一些東西，你需要相應的-devel包。然後，您還將獲得帶有標題的include/文件夾。

順便說一句，感謝這個回購的維護者。很高興有LLVM 3.9開箱。

Answer 2

有實現這個更簡單的方法：

添加Alonid的回購協議/etc/yum.repos.d/epel.repo（假設你已經安裝EPEL回購）

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 

然後，只需sudo yum install clang-3.9.0

Answer 3

我是作家您提到的RPM存儲庫的信息。從資源庫中的主要鉻渣頁面

如下：

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

如果您有任何問題，你可以從那裏與我聯繫。謝謝！

Answer 4

通過啓用SCL存儲庫，您可以使用llvm-toolset-7包在CentOS 7上安裝Clang 4。

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

啓用llvm-toolset-7：

$ scl enable llvm-toolset-7 bash
