GUN Compiler Collection GCC is referred to, in addition to the compiler, it also contains other tools, it can easy to source code written in high-level language used by humans to build into binary code a computer can directly execute. GCC is the most commonly used Linux platform compiler, it is the de facto standard Linux platform compiler. Meanwhile, in the field of embedded development on Linux platform, GCC is using the most common type of compiler. The reason why the GCC is widely used, because it can support a variety of different target architectures. For example, both support the development of the host (for a simple platform is to say the compiler, it is compiled on the platform), also supports cross compiler (i.e., A on the platform is a compiled program for use in platform B). Currently, GCC supports architecture more than forty kinds, common with X86 series, Arm, PowerPC and so on. Meanwhile, GCC can run on different operating systems, such as Linux, Solaris, Windows and so on.
In addition to talking about other than the above, GCC addition to supporting C language, also supports a variety of other languages, such as C ++, Ada, Java, Objective-C, FORTRAN, Pascal, go and so on.
Basically when compiling many applications need to install gcc, commonly used version is not very high so quickly through the installation command:
yum install -y gcc-c++
However, some applications require a higher version of gcc compile time, this time basically can only compile the installation, and installation is very troublesome gcc compiler, the compiler needs to rely on a few components to specify the version of the installation is successful, to facilitate the installation of a specially prepared installation shell script, the script unattended installation, of course, the installation process is a bit long to compile the script temporarily only supports CentOS system (system version 5 to 7 has been tested) to install under (other systems need to be adjusted quickly command yum install components and the corresponding installation package name)

Instructions:
In the root account, create a shell script file a .sh suffix, such as: gcc-install.sh and save the installation code is written above.
The installation command
bash gcc-install.sh new
If the system relies too small lead to an unsuccessful installation, you need to increase the corresponding dependencies (here only as an example to test the system dependencies that may be installed is not very adequate), you can go to the installation directory configuration changes in the installation script, the installation will succeed Tip a successful installation copy.
