If you are interested in building more compilers available in the GCC collection modify the –enable-languages configure option. The above command instructs the configure app to add a prefix to all the resulting executable programs, so for example if you want to invoke GCC 10.1.0 you will write gcc-10.1, the gcc command will invoke Apple’s version of clang. configure -prefix=/usr/local/gcc-10.1.0 \ 5 -enable-checking=release \ 6 -enable-languages=c,c++,fortran \ 7 -disable-multilib \ 8 -with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk \ 9 -program-suffix=-10.1 Be prepared that this could take some time … Since I’m interested only in the C, C++ and Fortran compilers, this is the configure command I’ve used on my machine: 1 cd ~/gcc_all/gcc-10.1.0 2 mkdir build & cd build 3 4. 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 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.
Mac python install gcc code#
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 a few 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. If you are using Catalina (macOS 10.15) check this tutorial.Ĭlang, the default compiler for macOS, supports only C, C++, Objective-C and Objective-C++. The instructions from this tutorial were tested with latest version of Command Line Tools and Mojave (macOS 10.14).
Mac python install gcc how to#
In this tutorial, I will show you how to compile from source and install the current stable version of GCC on your macOS computer.
