Build-automation tools

These build-automation tools will provide the infrastructure for building and linking the projects presented in the recipes. What you will end up installing and using strongly depends on your operating system and your taste:

• On GNU/Linux, GNU Make will most likely be installed automatically, when installing the compilers.
• On macOS, XCode will provide GNU Make.

• On Windows, Visual Studio will provide you with the complete infrastructure. In the MSYS2 environment, GNU Make is installed as a part of the mingw64/mingw-w64-x86_64-toolchain package, which we installed previously.

For maximum portability, we have made the recipes as agnostic about these system-dependent details as possible. A clear advantage of this approach is that configuring, building, and linking are native to each platform and each set of compilers.

The Ninja program is a different build-automation tool that works on GNU/Linux, macOS, and Windows. Ninja is a new build tool, with a focus on speed, especially for incremental rebuilds. Prepackaged binaries for GNU/Linux, macOS, and Windows can be found on the project's GitHub repository at https://github.com/ninja-build/ninja/releases.

Using CMake and Ninja with Fortran projects requires some care. CMake 3.7.2 or later is required, along with the version of Ninja maintained by Kitware, available at https://github.com/Kitware/ninja/releases.

On GNU/Linux, you can install Ninja with the following series of commands:

$ mkdir -p ninja
$ ninja_url="https://github.com/Kitware/ninja/releases/download/v1.8.2.g3bbbe.kitware.dyndep-1.jobserver-1/ninja-1.8.2.g3bbbe.kitware.dyndep-1.jobserver-1_x86_64-linux-gnu.tar.gz"
$ curl -Ls ${ninja_url} | tar -xz -C ninja --strip-components=1
$ export PATH=$HOME/Deps/ninja${PATH:+:$PATH}

On Windows, using the MSYS2 environment (assuming the 64-bit version), executing the command:

$ pacman -S mingw64/mingw-w64-x86_64-ninja
