First let me say I’m not a big Fortran user but any blog posts about Fortran always seem to be very popular, and I do get asked regularly about how to compile Fortran applications.

NAG Fortran compiler Fortran compiler for Apple Silicon Macs now available to download.

Absoft Pro Fortran 2021 For macOS and OS X.

gfortran for ARM Big Sur (macOS 11.0) and Apple Silicon.

I suspect this will be of interest.

Fortran Package Manager (fpm) is a package manager and build system for Fortran. Its key goal is to improve the user experience of Fortran programmers. It does so by making it easier to build your Fortran program or library, run the executables, tests, and examples, and distribute it as a dependency to other Fortran projects. Fpm's user interface is modeled after Rust's Cargo, so if you're familiar with that tool, you will feel at home with fpm. Fpm's long term vision is to nurture and grow the ecosystem of modern Fortran applications and libraries.

If you have followed the instructions on Cheminformatics on a Mac you already have Xcode, Command Line tools and gfortran installed using Homebrew. Alternatively you can install GCC 8.3 (auto-vectorizing gcc with OpenMP) which includes gfortran (free, open source, GNU Fortran 95 compiler), gcc (GNU C) and g++ (GNU C++) compilers that can perform auto-vectorization (i.e. modify code to take advantage of AltiVec/SSE, automatically) and other sophisticated optimizations like OpenMP. There are detailed instructions here, last updated April 2019 (Mojave).

Portland group also has a commercial fortran compiler as part of their offerings (PGI).PGI Compilers & Tools have evolved into the NVIDIA HPC SDK.

The newest update to PGI Fortran, C and C++ compilers & tools for scientists and engineers. Includes Volta support, using CUDA Unified Memory with OpenACC, Open 4.5 CPU support, C++14 lambda and capture support within OpenACC and…. On Intel Haswell CPUs with OpenMP, PGI delivers multicore performance more than 50% faster than the latest GCC compilers. That’s like buying a cluster with 50% more compute nodes. PGI compilers deliver world-class multicore CPU performance and accelerator programming features that can dramatically increase the performance of applications on GPU accelerators. New features include V100 Tensor Core support, full C++17 language support, OpenACC printf(), PCAST directives, LLVM 7.0, Turing support.

There is also a free version of the PGI compiler released April 30, 2019

Absoft Pro Fortran 2021 For macOS and OS X.

Fully compatible with macOS Big Sur (11.0)Pro Fortran builds faster code with exclusive Dynamic AP load balancing, SMP analysis, and advanced optimization. The AbsoftTools integrated development environment speeds program development and maintenance. Complete command-line development support is also provided. The OS X Fortran compiler supports a full range of project targets including command-line programs and GUI based applications. It provides a complete 64-bit macOS/OS X Fortran compiler solution and supports mixed language development by interfacing with Apple’s Xcode C/C++ compiler.

Pro Fortran for macOS System Requirements

Intel CPU based system – multi-core suggested for best performance
macOS Sierra (10.12) through macOS Big Sur (11.0)
OS X Snow Leopard (10.6) through OS X El Capitan (10.11)
2 GB RAM – 4 GB recommended for best performance
1 GB free disk space for complete installation

Arguably the best fortran compiler for Intel macs are the Intel compilers ifort.

The Intel® Fortran Compiler builds high-performance applications by generating optimized code for Intel® Xeon® Scalable processors and Intel® Core™ processors. Its features allow you to: Boost Single Instruction Multiple Data (SIMD) vectorization and threading capabilities (including for Intel® Advanced Vector Extensions 512 instructions) using the latest OpenMP* parallel programming modelTake advantage of more cores and increased vector register width available in Intel® Xeon® processorsComply with open standards such as Fortran and OpenMPWork with a familiar set of tools on your preferred platform: Windows, Linux, or macOS*

They can build pretty much any fortran code including very old fortran (as far back as fortran 66) and support the latest fortran standards. And in many people’s experience produce the fastest runtime executables. They also integrate directly into Xcode and tend to be the most up to date in terms of compatibility with the apple dev tools. They are also link compatible with both gcc and clang. ifort also includes a fortran version of their MLK library.

They provide redistribute libraries for dynamically linked binaries, but they also support static linking, so in either case binaries can be distributed to people without the compiler installed.They aren't free on Mac (they are free on Linux), but the academic price is relatively inexpensive. Additionally they have a C/C++ compiler suite, but the performance gain over clang is no longer there. They are better than gcc in terms of codgen, however. So if you aren't using MLK there may be no benefit.

NAG Fortran Compiler.

The NAG Fortran Compiler provides significant support for Fortran 2018 (atomic operations, events and tasks, plus other smaller features), almost all Fortran 2008, complete coverage of Fortran 2003, and all OpenMP 3.1. All platforms include supporting tools for software development: source file polishers, dependency generator for module and include files, call-graph generator, interface builder and a precision unifier. Available on Linux, Windows and macOS, including Apple Silicon Macs. They also provide a NAG Fortran IDE for Macs.

Given the move towards parallel processing it is useful to note that most of the compilers support OpenMP, OpenMP is a specification for a set of compiler directives, library routines, and environment variables that can be used to specify high-level parallelism in Fortran and C/C++ programs.

Compiling Fortran applications on a Mac

If you have Homebrew installed then the easiest way to install gfortran is as part of gcc. I’ve written a page of instructions for setting up a Mac using Homebrew here.

We can check gfortran is installed using, in the Terminal type

and the location

which should be an alias to '/usr/local/Cellar/gcc/4.8.3/bin/gfortran'

An Example

Critic2: A program for real-space analysis of quantum chemical interactions in solids DOI

Download critic2 from: http://gatsby.ucmerced.edu/downloads/critic2/critic2-1.0.tar.gz

Once downloaded:

This compiles and installs:
- critic2, basin2off, off2off, charges.sh executables to /usr/local/bin
- data files to /usr/local/share/critic2
- help files to /usr/local/share/doc/critic2

A couple of Fortran experts have contacted me and suggested I include these flags that are often very useful for developers.

-static-libgcc : includes all necessary system routines in the binary and thus avoids error messages at runtime when some library is missing on the user computer

-mmacosx-version-min=10.1 : generates binaries able to work under several os x versions

-fno-underscoring : supresses the trailing undersore for names of functions and subroutines (but then you must take care about conflicting names)

ABINIT is a software suite to calculate the optical, mechanical, vibrational, and other observable properties of materials. Starting from the quantum equations of density functional theory, you can build up to advanced applications with perturbation theories based on DFT, and many-body Green's functions (GW and DMFT) . Compilation/Installation notes are here.

BigDFT a DFT massively parallel electronic structure code (GPL license) using a wavelet basis set. Wavelets form a real space basis set distributed on an adaptive mesh (two levels of resolution in our implementation). GTH or HGH pseudopotentials are used to remove the core electrons. Thanks to our Poisson solver based on a Green function formalism, periodic systems, surfaces and isolated systems can be simulated with the proper boundary conditions. Source code.
