Linux CentOS 6.5 Manually upgrade GCC to Gcc-6.1.0_linux

It's been years since we got into the code farming era, has not written the habit of blogging, used a lot of things no record, to the back of the forgotten, need to use, and constantly Baidu Google, time and energy, not necessarily can find a satisfactory answer, so open a blog record. (No more nonsense)

Today on the company server source code installation NODEJS error warning:c++ compiler too old, need g++ 4.8 or clang++ 3.4 (cxx=g++), direct yum update GCC can not upgrade to 4.8, and can only manually Disposed of.

Start, if Linux installs the wget command:

wget http://ftp.gnu.org/gnu/gcc/gcc-6.1.0/gcc-6.1.0.tar.gz
tar-zvxf gcc-6.1.0.tar.gz--directory=/usr/local/
cd/usr/local/gcc-6.1.0
./contrib/download_prerequisites 
mkdir build && CD build 
. /configure-enable-checking=release-enable-languages=c,c++-disable-multilib make 
&& make install

If it is installed on a virtual machine, it may take more than 3-4 hours to wait patiently, juvenile ...

If, if your Linux is very strong, do not install wget command, or can not access the extranet, how to do??? Keep looking down:

First download the latest GCC (http://ftp.gnu.org/gnu/gcc/), I used the gcc-6.1.0.tar.gz, uploaded to Linux via FTP, decompression:

TAR-ZVXF gcc-6.1.0.tar.gz--directory=/usr/local/
cd/usr/local/gcc-6.1.0

Then use VI to open the./contrib/download_prerequisites file to see which dependencies you need for the currently downloaded GCC. When you open it, you see the following:

From this, we also need to download gmp-4.3.2.tar.bz2, isl-0.15.tar.bz2, mpc-0.8.1.tar.gz, mpfr-2.4.2.tar.bz2, note that the dependency package must be specified version, otherwise there will be problems. Download a good dependency package, extract directly to the/usr/local/gcc-6.1.0/directory, and then set up soft Links:

LN-SF gmp-4.3.2 GMP
ln-sf isl-0.15 ISL
ln-sf mpc-0.8.1 MPC
ln-sf mpfr-2.4.2 MPFR

Once you have set it up, you are ready to start installing:

mkdir build && CD Build 
... /configure-enable-checking=release-enable-languages=c,c++-disable-multilib make 
&& make install
