How to install CLang using precompiled binaries?

Question

How do I install CLang on Ubuntu, using precompiled binaries of CLang that I downloaded?

Here's how I downloaded CLang: "LLVM Download Page" -> "Download LLVM 3.2" -> "Clang Binaries for Ubuntu-12.04/x86_64" ( http://llvm.org/releases/3.2/clang+llvm-3.2-x86_64-linux-ubuntu-12.04.tar.gz .)

Then, I expanded the archive into a folder on my Ubuntu 12.04 LTS 64-bit machine. The contents of the expanded folder look like this:

$ ls clang+llvm-3.2-x86_64-linux-ubuntu-12.04
bin  docs  include  lib  share

Question: What do I do next? Do I have to copy these into some folders myself, and if so, which ones exactly? Most instructions I found online are for building CLang from source, which doesn't apply here.

I am a newbie to most of these tools. I created a basic hello-world C++ program, and was able to compile and run it, using GCC and autotools. Now, I want to compile the same program with CLang.

You can follow the same step as mentioned in https://askubuntu.com/questions/89615/how-do-i-install-llvm-clang-3-0

using GNU tar:

wget <clang-binaries-tarball-url> #  or `curl -O <url>`
tar xf clang*
cd clang*
sudo cp -R * /usr/local/

If your tar isn't GNU and

• the archive you get is .tar.gz, you can use tar -xzf;
• if you have .tar.xz archive, you can use tar -xJf;
• for .tar.bz2 archive, you can use tar -xjf.
