[llvm-dev] libcxx build error.

[Srikanth Bemineni via llvm-dev]

Hi,

I am trying to build llvm 3.4.2 on Centos 6.6. I am getting this below
build error , while building the libcxx. I followed the build procedure
based of http://clang.llvm.org/get_started.html. I cannot move to a higher
version, Since we need to develop on CentOS 6.6  and LLVM 3.4.2 ,is the
last version that supports gcc 3.4.2. Starting from LLVM 3.5.0, there has
been a huge  jump to gcc 4.7.0.

I am just starting to get acquainted to LLVM. So please bare with my
questions.
