The above four prerequisites will be built during the GCC build. GCC 10 depends on a couple of other libraries (GSL, GMP, MPFR and ISL) that can be downloaded with: 1 cd gcc-10.1.0 2 contrib/download_prerequisites Next, we can download and extract the latest stable version of GCC: 1 curl -L | tar xf. Let’s start by creating a working folder: 1 cd ~ 2 mkdir gcc_all & cd gcc_all Which will guide you through the installation process. If you don’t have the Command Line Tools installed, open a Terminal and write: 1 xcode-select -install At the time of this writing Apple’s Command Line Tools maps the gcc and g++ to clang and clang++. In the remaining of this article I will assume that you have installed the Command Line Tools for Xcode. In order to compile GCC from sources you will need a working C++ compiler.

Testing your code with two different compilers is always a good idea.īuilding GCC 10 from sources could take some time, in my case it took about two hours on a MacBook Air with a 16GB of RAM. Another reason to have the latest stable version of GCC on your macOS is that it provides you with an alternative C and C++ compiler. you will need gfortran that comes with GCC. If you are interested in a modern Fortran compiler, e.g. The instructions from this tutorial were tested on Catalina (macOS 10.15).Ĭlang, the default compiler for macOS, supports only C, C++, Objective-C and Objective-C++. In this tutorial, I will show you how to compile from source and install the current stable version of GCC on your macOS computer.
