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?
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:

If you have any question, you can contact me from there. Thanks!
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.
A complete installation process is provided by Red Hat, please refer to Red Hat documents.
