GCC, the GNU Compiler Collection - GNU Project
The GNU Compiler Collection includes front ends for C, C++, Objective-C, Objective-C++, Fortran, Ada, Go, D, Modula-2, COBOL, Rust, and Algol 68 as well as libraries for these languages (libstdc++,...). GCC was originally written as the compiler for the GNU operating system.

GCC, the GNU Compiler Collection 15.1 released
I've been using the latest git sources since some weeks. In general most software I try to compile, worked quite well. I have had a few issues with some C++ code bases though. I don't know whether 15.1 fixed those issues, but I'll eventually find out. It would be good if someone could have a test-infrastructure, to automatically report projects that are failing (I don't track all projects, but e. g. debian could probably try to compile tons of software automatically via a new GCC release and then report that systematically as well. Perhaps that is already done on github, but several projects I tried to compile with the git checked-out GCC did not compile, whereas the latest stable GCC 14.2.0 had no problem with the same source code, so I am not really certain anyone really checks that. I only discovered that semi-accidentally; should probably keep a local log file which projects failed ... will do so next time I see such problems.) More on reddit.com

Whats "gcc-arm-none-eabi" toolchain ??
Gcc-arm-none-eabi is the gcc compiler toolchain for arm outside of a hosted environment. This means that it compiles bare metal code: code running without an already existing OS. βNormalβ gcc uses libraries from the system where its installed, so if you compile a hello world links to and uses the standard library. Gcc-arm would mean that the compiler is a cross compiler: its installed on your system but it compiles for arm. On an arm processor could run a full fledged linux environment so a gcc-arm-aarch64-linux or something like that would compile a program on your pc for that arm system running linux. Now there are meriads of arm systems not running linux which needs code to be compiled for as well. This is the place for the none-eabi variant: it does not use any system library and uses a standard interface for calling functions and other stuff. So in other words this is just the bare metal cross compiler for arm systems. And who makes these? Anyone who wants to. Gcc is an open source project and anyone could compile the toolchain. With compiling you can βselectβ your version: do you want to build a linux-on-riscv compiler running on your pc? Definitely possible! The linux distro repos contain a couple of standard versions of gcc of which arm-none-eabi is one More on reddit.com

Using the C++14 language version is supported in Red Hat Developer Toolset when all C++ objects compiled with the respective flag have been built using Red Hat Developer Toolset 6 or later. Objects compiled by the system GCC in its default mode of C++98 are also compatible, but objects compiled with the system GCC in C++11 or C++14 mode are not compatible.

GNU Compiler Collection (GCC) - Department of Scientific Computing
The GNU Complier Collection (GCC) is an integrated compiler that can compile programs written in C, C++, and Fortran. GCC is both the most general name for the compiler suite, and the name used when the emphasis is on compiling C programs (as the abbreviation formerly stood for "GNU C Compiler").

gcc and g++ are compiler-drivers of the GNU Compiler Collection (which was once upon a time just the GNU C Compiler).
Even though they automatically determine which backends (cc1 cc1plus ...) to call depending on the file-type, unless overridden with -x language, they have some differences.
The probably most important difference in their defaults is which libraries they link against automatically.
According to GCC's online documentation link options and how g++ is invoked, g++ is roughly equivalent to gcc -xc++ -lstdc++ -shared-libgcc (the 1st is a compiler option, the 2nd two are linker options). This can be checked by running both with the -v option (it displays the backend toolchain commands being run).
By default (and unlike gcc), g++ also adds linker option -lm -- to link against libm which contains implementations for math.h.

GCC: GNU Compiler Collection
- Referrers to all the different languages that are supported by the GNU compiler.
gcc: GNU C Compiler
g++: GNU C++ Compiler
The main differences:
gccwill compile:*.c\*.cppfiles as C and C++ respectively.g++will compile:*.c\*.cppfiles but they will all be treated as C++ files.- Also if you use
g++to link the object files it automatically links in the std C++ libraries (gccdoes not do this). gcccompiling C files has fewer predefined macros.gcccompiling*.cppandg++compiling*.c\*.cppfiles has a few extra macros.
Extra Macros when compiling *.cpp files:
#define __GXX_WEAK__ 1
#define __cplusplus 1
#define __DEPRECATED 1
#define __GNUG__ 4
#define __EXCEPTIONS 1
#define __private_extern__ extern
