About:
The GNU Compiler Collection (GCC) is a cornerstone of software development, providing compilers for C, C++, Fortran, Ada, and other languages. This formula installs GCC version 9, which is essential for compiling software that requires this specific toolchain version for compatibility or legacy support. It enables developers to build robust, high-performance applications from source code on various platforms.

Key Features:

Supports multiple programming languages including C, C++, and Fortran
Provides a specific, versioned toolchain (v9) for compatibility
Optimizes code for high-performance execution
Open-source and widely used standard for compilation

Use Cases:

Compiling legacy software projects that require GCC 9
Developing applications that depend on specific C++ standard library versions
Building open-source software from source on macOS or Linux

Alternatives:

clang – LLVM-based compiler, often the default on macOS; known for faster compilation and better error messages.
gcc@13 – Newer GCC formula offering support for the latest language standards and features.
