If you are a Fortran programmer, you can use some of the Fortran 2008 features like do concurrent with gfortran-10.1: 1 integer, parameter :: mm = 100000 2 real :: a ( mm ), b ( mm ) 3 real :: fact = 0.5 4 5 ! initialize the arrays 6 !. In your favorite text editor, copy and save this test program (I’ll assume you will save the file in your Home directory): 1 //Program to test the C++ lambda syntax and initializer lists 2 #include 3 #include 4 5 int main () 6

GCC 10 uses by default the C++14 standard and C11 for the C coders, you should be able to compile any valid C++14 code directly.

Next, I’ll show you how to check if the compiler was properly installed by compiling and running a few examples. Remember to erase the working folder from your HOME if you want to recover some space: 1 cd ~ 2 rm -rf gcc_all You should be able to invoke any of the newly compiled compilers C, C++, Fortran …, invoking g++ is as simple as writing in your Terminal: 1 g++-10.1 test.cpp -o test bash_profile from your Home folder, e.g: 1 echo 'export PATH=/usr/local/gcc-10.1.0/bin:$PATH' > ~/.bash_profile 2 source ~/.bash_profile If you want to avoid writing the above command each time you open a Terminal, save the above command in the file. Now, you can keep the new compiler completely isolated from your Apple’s gcc compiler and, when you need to use it, just modify your path by writing in Terminal: 1 export PATH=/usr/local/gcc-10.1.0/bin:$PATH

Install the compiled gcc in /usr/local/gcc-10.1.0: 1 sudo make install-strip Grab a coffee, maybe a book, and wait … this should take approximately, depending on your computer configuration, an hour … or more … and about 4 GB of your disk space for the build folder. 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. 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). In this tutorial, I will show you how to compile from source and install the current stable version of GCC on your macOS computer.
