If you have the most recent Apple Command Line Tools (macOS 10.nn) for Xcode installed for your operating system version — which you get from developer.apple.com/download/more, then you need a package manager (e.g. homebrew) to install, and compile GCC and all of its dependencies. That compilation process will take at least an hour. After you initially install homebrew (brew):

# In the bash shell (e.g. .bash_profile), gag Google Analytics in Homebrew.

export HOMEBREW_NO_ANALYTICS=1

brew update

brew upgrade

brew info gcc

brew install gcc

brew cleanup (this removes previous application/dependency revisions saving considerable space)

The gcc application will be installed by default in /usr/local/bin.

Personally, I use Apple’s clang/clang++ compilation tools rather than deal with GNU gcc.

Mac OS X: Install GCC Compiler with Xcode

I have Mac OS X Mountain Lion. I need to compile a few apps and Perl modules. I already installed Xcode from app store but I’m unable to find gcc compiler or make command. How do I install gcc on Mac OS X 10.8.x?

Xcode includes command line development tools such as gcc and friends.

Step #1: Install Xcode on a Apple Mac OS X

First, make sure Xcode is installed. If it is not installed on OS X, visit app store and install Xcode.

Fig.01: Make sure Xcode developer tools are install OS X

Step #2: Install gcc/LLVM compiler on OS X

Once installed, open Xcode and visit:

Xcode menu > Preferences > Downloads > choose » Command line tools » > Click » Install » button:

Step #3: Verification

Open a terminal app and type the following commands:
$ gcc —version
$ whereis gcc
$ whereis make
Sample outputs:

Testing sample “Hello world” C program

Create a text file called a.c as follows using a text editor such as vi or cat command:

/* a.c — demo for os x */ #include int main(void)

To compile, enter:
$ make a
Run it as follows:
$ ./a
Sample outputs:

And, there you have it, the gcc version 4.2.1 installed and working correctly on the latest version of Mac OS X 10.8.4. In Apple’s version of GCC, both cc and gcc are actually symbolic links to the llvm-gcc compiler. Similarly, c++ and g++ are links to llvm-g++. For more information and examples see the following man pages:

Oh for * sake. I wanted to install GCC, not xcode! FYI, xcode is not gcc. Also, xcode doesn’t contain gcc, but LLVM. There is slight, but definite difference.

One good approach to work with GCC in mac is to install docker and run a container with GCC and mount a directory with the container. That’s it

I love how sometimes people give the simplest answers that do not really answer the ACTUAL question people are asking. This is how to install the clang/llvm gcc front end which is NOT gcc.

Muchas muchas gracias!

I wanted to install GNU GCC, not clang

This installs LLVM, not GCC. Type gcc –help and check the first lines.

A comprehensive and useful compiler system that comes with in-built front-ends and libraries designed to support a wide variety of programming languages

What’s new in GCC 10.2.0:

• Caveats:
• An ABI incompatibility between C++14 and C++17 has been fixed. On some targets a class with a zero-sized subobject would be passed incorrectly when compiled as C++17 or C++20. See the C++ notes below for more details.
• The deprecated Profile Mode and array_allocator extensions have been removed from libstdc++.

Read the full changelog

The GNU Compiler Collection or GCC for short, comprises front ends for C, Objective-C, C++, Java, Fortran, Go and Ada, along with libraries for the mentioned languages.

GCC us the main component of the GNU toolchain, it is distributed under the GNU General Public License and plays a central role in the continuous growth of free software.

Take advantage of the support for numerous programing languages

Initially, GCC handled only the C programming language, but with the development of additional front ends, GCC expanded to compile C++, Objective-C, Objective-C++, Go, Fortran, Ada, Java and others.

GCC also offers support for a wide variety of processor architectures and, as a result, it is frequently used as a development tool for both free and proprietary apps. GCC is also available for most embedded platforms, including AMCC, Symbian and Freescale Power Architecture-based chips.

Compatible with various processor architectures

The GNU Compiler Collection also targets various platforms, such as video game consoles like Dreamcast and PlayStation. Moreover, GCC is the standard compile for numerous Unix-like operating systems, including Linux and the BSD family, FreeBSD and LLVM system.

Thanks to GCC’s Link-time optimization feature it optimizes across object file boundaries in order to improve the linked binary. Link-time is based on intermediate files containing the serialization of various Gimple representation present in the object file.

Expandable through plugins

Moreover, the use of plugins enables you to extend the GCC compiler and modify stock compilers to fit specific needs by loading external codes as plugins. As follows, you can use plugins to add, remove and replace middle-end passes operating on Gimple representations.

Detailed installation instructions along with the provided documentation are available on GCC’s Installation webpage.

In conclusion, GCC is a comprehensive collection of libraries and front ends that enable you to compile source code into binary application.
