GCC Latest version installation and error resolution

Linux under GCC installation

1. Preparation work

Linux can typically install GCC directly from a package, for example, but not usually the latest version, such as the need to support c++11

And so on, you will need to install the latest version of GCC.

View the existing GCC versions first

If the system does not have any GCC installed, you will need to install the default low version of GCC from the development pack first

CentOS can also be installed with GCC development tools: Yum Groupinstall "Development Tools"

The following error may occur if you do not install the previous version first:

Because of the lack of GCC dependent GMP, MPFR, MPC three software, so need to download and install them, they're on top of the
Infrastructure folder can be found inside. At the same time, GMP and MPFR and MPC are also interdependent relationship, so
To install in the following order, and with the options behind the Configure, follow the path of the dependent software

Download all the files and unzip them as follows:
