The Fortran language track requires that you have the following software installed on your system:
- a modern Fortran compiler
- the CMake cross-platform build system
This language track requires a compiler with Fortran 2003 support. All major compilers released in the last few years should be compatible, so as long as you are on a fairly recent version you should be fine.
The following will describe installation of GNU Fortran or GFortran. Other fortran compilers are listed here. Intel Fortran is a popular proprietary choice for high performance applications. Most exercises will work with Intel Fortran, but are only tested with GNU Fortran so your milage may vary.
CMake is an open source cross-platform build system that generates build
scripts for your native build system (make, Visual Studio, Xcode, etc.).
Exercism's Fortran track uses CMake to give you a ready-made build that:
- compiles the tests
- compiles your solution
- links the test executable
- automatically runs the tests as part of every build
- fails the build if the any tests fail
Using CMake allows exercism to provide a cross-platform build script that can generate project files for integrated development environments like Visual Studio and Xcode. This allows you to focus on the problem and not worry about setting up a build for each exercise.
Getting a portable build isn't easy and requires access to many kinds of systems. If you encounter any problems with the supplied CMake recipe, please report the issue so we can improve the CMake support.
CMake 2.8.11 or later is required to use the provided build recipe.
Ubuntu 16.04 and later have compatible compilers in the package manager, so
installing the necessary compiler can be done with sudo apt-get install gfortran cmake.
For other distributions, you should be able to acquire the compiler through your package manager.
MacOS users can install GCC with Homebrew via
brew install gfortran cmake.
Windows users can get GNU Fortran through MingW. The easiest way is to first install chocolatey. nd then type in a administrator cmd shell:
choco install mingw cmake
This will install MingW (GFortran and GCC) to C:\tools\mingw64 and CMake to C:\Program Files\CMake. You should add the bin directories of these installations to your PATH, ie.:
set PATH=%PATH%;C:\tools\mingw64\bin;C:\Program Files\CMake\bin
