CentOS 6.7上的“ gcc：尝试执行'cc1plus'错误：execvp：没有这样的文件或目录”

Question

I have a really strange thing going on on my computer. I did lookup for similar questions but the solutions there did not help me out.

I am trying to install bazel 0.2.2b on Cent OS 6.7. Bazel requires gcc 4.8 or higher to compile so I upgraded my gcc to 4.8.2 uisng the steps given here .

I did an scl enable after the installation but nothing changed. My default gcc was still 4.4.7. SO I did the following steps:

sudo mv /usr/bin/gcc /usr/bin/gcc.bak
sudo cp /opt/rh/devtoolset-2/root/usr/bin/gcc /usr/bin/gcc
sudo mv /usr/bin/g++ /usr/bin/g++.bak
sudo cp /opt/rh/devtoolset-2/root/usr/bin/g++ /usr/bin/g++

Since removing gcc was dangerous, i moved it to another file and copied the new one into /usr/bin/gcc.

Now, my default gcc and g++ are both 4.8.2 but I still get the error:

gcc: error trying to exec 'cc1plus': execvp: No such file or directory

When I do ./compile to install Bazel.

I tried solutions posted in other similar questions asking to upgrade/re-install but to no use.

$ yum install gcc-c++

You need to be root to perform this command.
[sree@ds1 bazel]$ sudo yum install gcc-c++

Package gcc-c++-4.4.7-17.el6.x86_64 already installed and latest version
Nothing to do

I am worried I might break the system core if I do anything wrong. What should I do now?

CentOS 6.8 - 64bits :

The git versiom, git clone https://github.com/bazelbuild/bazel.git fails .

( cd bazel/ && scl enable devtoolset-2 bash && sh compile.sh )

And bazel-0.2.2b fails too.

The installer bazel-0.3.0-installer-linux-x86_64.sh works OK ... https://github.com/bazelbuild/bazel/releases/download/0.3.0/bazel-0.3.0-installer-linux-x86_64.sh

su    
sh bazel-0.3.0-installer-linux-x86_64.sh
