Centos6_64 under the Gcc-c++ platform to build __c++

Installation Method Automatic Installation

    Yum Install gcc     (this is)
    yum install gcc-c++ (this is the C + + compiler)
    Yum install

However, this does not install the specified version to install only the version of the system disk, the following CentOS 6x64 install GCC 4.8.4 For example, Custom install 1. Install gcc4.8.4 for small white (actually I am one)

The following CD XX means to enter a directory by default in the root directory
Cd.. Or ' represents a return to the root directory
Wget means to get a download from the network location 1 Download Source

Wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.4/gcc-4.8.4.tar.bz2 (You can change the version number here according to different needs)

2) Unzip and download the project required for compiling

TAR-JXVF  gcc-4.8.4.tar.bz2
cd gcc-4.8.4
./contrib/download_prerequisites
CD. (Back to the root directory here. Can be replaced by a space)

3 Generate directories and makefile and compile

mkdir gcc-build-4.8.4 (Create a directory under Root to store)
CD  gcc-build-4.8.4 
. /gcc-4.8.4/configure--enable-checking=release--enable-languages=c,c++--disable-multilib
make-j4 (* After this step is a long wait ~ do not think it is the crash ... *

4) Installation

sudo make install

5) Check version number

GCC--version or-v

Using built-in specs.
COLLECT_GCC=GCC
Collect_lto_wrapper=/usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.8.4/lto-wrapper
Target:x86_64-unknown-linux-gnu
Configured with:. /configure--enable-checking=release--enable-languages=c,c++--disable-multilib
Thread model:posix
gcc Version 4.8.4 (GCC)

2. Install CMake 1) Get Source ditto

Wget http://www.cmake.org/files/v3.4.2/cmake-3.4.2.tar.gz (now updated to 3.5 according to individual needs, this version is relatively stable)

2) Decompression and access to the directory

TAR-ZXVF cmake-3.4.2.tar.gz
CD cmake-3.4.2

3 Important and easily error-prone parts

./bootstrap

Well, there's a combination of requirements, the first two to continue .

cp/usr/local/lib/libstdc++.so.6.0.20  /usr/lib/(copied to usr directory)

Note that the directories under LIB64 will also be updated. Here no longer repeat the change suffix can error 2

Error when bootstrapping CMake:  
cannot find appropriate C (or C + +) compiler on this system.  
Please specify one using environment variable CC.  
Cmake_bootstrap.log for compilers attempted.  

Lack of a suitable C + + compiler, you should be concerned about whether the version of GCC matches, in this case, should be matched. ~ 4) Subsequent installation

Gmake
gmake Install
cmake--version

3. Verify

  fir.cc
#include <iostream>
using namespace std;

int main ()
{    
    cout << "Hello world!" <<endl;
    return 0;
}
CMD input
g++-std=c++11-o fir fir.cc
./fir.cc (if unable to run the description does not provide permissions plus permissions chmod +x)
