GNU GCC Compiler

The GNU Compiler Collection (GCC) is a foundational and highly versatile compiler system produced by the GNU Project, serving the critical function of translating source code written in a wide array of programming languages—most notably C, C++, Objective-C, and Fortran—into executable machine code. As a cornerstone of the free and open-source software movement, GCC is the standard compiler for most Unix-like operating systems, including Linux, and is an essential tool for developers building everything from operating system kernels to complex applications, making it a fundamental component in the software development toolchain.
