gcc vs gcc-base

1. gcc-7: "gcc-7" refers to the actual compiler package from the GCC version 7 series. GCC is a collection of compilers for various programming languages, including C, C++, and Fortran. The package "gcc-7" contains the complete set of tools and libraries for compiling and linking programs written in C, C++, and other supported languages using the GCC version 7 compiler. This includes the command-line tools like gcc, g++, gfortran, and related libraries.
2. gcc7-base: "gcc7-base" refers to the runtime support libraries that are required by programs compiled with GCC version 7. These libraries provide essential functions and resources that programs need to run successfully on the system. They are part of the base runtime environment that is needed to execute applications compiled with the GCC version 7 compiler. These libraries are not directly used for compiling, but rather for running programs.

In summary:

• gcc-7: This is the compiler package itself, providing the tools and libraries required to compile and build programs using the GCC version 7 compiler.
• gcc7-base: This includes the runtime support libraries that are necessary for executing programs that have been compiled with the GCC version 7 compiler. These libraries are essential for running applications on the system.
