Necessary matters for installing GCC:

GCC can be used to compile programs in C/C, FORTRAN, Java, OBJC, ADA and other languages. You can choose according to your needs. Install supported languages.

Before installation, a compiler such as cc or gcc must be available in the system, or use the environment variable CC to specify the compiler on the system. GCC 4.1.2 cannot be installed from source if the compiler is not present on the system. If this is the case, you can find a GCC software package in binary form such as RPM that is suitable for the system on the Internet to install and use.

The original GCC compiler on the system may store gcc and other command files, library files, header files, etc. in different directories in the system.

Unlike this, GCC now recommends installing a version of GCC in a separate directory. The advantage of this is that you can easily delete the entire directory when you no longer need it in the future (because GCC does not have an uninstall function); the disadvantage is that you need to do some setup work after the installation is completed to make the compiler work properly.
