问题
I have taken rpm packages from https://copr-be.cloud.fedoraproject.org/results/alonid/llvm-3.9.0/epel-7-x86_64/00505197-clang-3.9.0/ for Clang 3.9.
I am installing the rpm packages by the command
rpm -ivh clang-3.9.0-3.9.0-3.1.el7.centos.alonid.src.rpm
But when I do
rpm -ivh clang-3.9.0-3.9.0-3.1.el7.centos.alonid.x86_64.rpm
I get the following error :
error: Failed dependencies:

Where should I install all these dependencies from?
回答1:
By enabling the SCL repository you can install Clang 5.0.1 on CentOS 7 using the llvm-toolset-7 package.
$ sudo yum install centos-release-scl
$ sudo yum install llvm-toolset-7
Enable llvm-toolset-7:
$ scl enable llvm-toolset-7 bash
You can now check you clang version with:
$ clang --version
See this Red Hat blog post for more information.
For more information about SCL, see this page.

There was a much easier way to achieve this:
Add the Alonid's repo to /etc/yum.repos.d/epel.repo (assuming you have epel repo installed)
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
Then just sudo yum install clang-3.9.0

I am the author of the RPM repository you mention.
Follow from the main Copr page of the repository:

Just open your link and look around, also go one level higher and find all necessary .rpm's. The following sequence worked for me:
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
By just doing yum install without any flags Clang and LLVM will be installed to /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
Also notice that there are other packages like -devel, -static, -debuginfo.
Useful tip: Without installing -devel packages you only get bin and lib64 folders where only the executables like bin/clang and libraries like lib64/libLLVM-3.9.0.so are located. If you also want to develop something with LLVM/Clang you will need corresponding -devel packages. Then you will also get include/ folder with headers.
By the way, thanks to the maintainers of this repo. Nice to have LLVM 3.9 out of the box.
