The Portable Operating System Interface (POSIX; IPA: / ˈ p ɒ z. ɪ k s / [ 1 ] ) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems . [ 1 ]
GCC is also available for many embedded systems, including ARM-based and Power ISA-based chips. As well as being the official compiler of the GNU operating system, GCC has been adopted as the standard compiler by many other modern Unix-like computer operating systems, including most Linux distributions.
