I recently downloaded code as mentioned in
http://clang.llvm.org/get_started.html link. My GCC version is 4.1.2. The
compilation went fine for at least an hour before the below error started to
occur in console.
The LLVM support stated that I need to use gcc44-c++, which is not available in our box:
Red Hat Enterprise Linux Server release 5.5 (Tikanga)
# yum install gcc44-c++

Setting up Install Process
No package gcc44-c++ available.
Nothing to do
Please let me know if gcc44-c++ actually means GCC 4.4 C++ compiler or it is a different compiler. If different please let me know how can I download and install the same for Red Hat 5.4 OS?

It means that you need GCC 4.4 (or higher). I’d suggest that you upgrade to the latest 4.7.
You will need to upgrade your compiler. A quick search reveals quite a few RPMs are available. Select one that fits your system.
