GitHub Action
Setup Fortran
Set up a Fortran compiler on Ubuntu, macOS and Windows runners.
jobs:
test:
runs-on: ${{ matrix.os }}
strategy:
fail-fast: false
matrix:
os: [ubuntu-latest, macos-latest, windows-latest]
toolchain:
- {compiler: gcc, version: 13}
- {compiler: intel, version: '2023.2'}
- {compiler: intel-classic, version: '2021.10'}
- {compiler: nvidia-hpc, version: '23.11'}
include:
- os: ubuntu-latest
toolchain: {compiler: gcc, version: 12}
exclude:
- os: macos-latest
toolchain: {compiler: intel, version: '2023.2'}

toolchain: {compiler: nvidia-hpc, version: '23.11'}
- os: windows-latest
toolchain: {compiler: nvidia-hpc, version: '23.11'}
steps:
- uses: fortran-lang/setup-fortran@v1
id: setup-fortran
with:
compiler: ${{ matrix.toolchain.compiler }}
version: ${{ matrix.toolchain.version }}
- run: |
${{ env.FC }} ... # environment vars FC, CC, and CXX are set
${{ steps.setup-fortran.outputs.fc }} ... # outputs work too
- compiler: Compiler toolchain to setup, available options are
- gcc (for
gfortran
) - intel (for
ifx
) - intel-classic (for
ifort
) - nvidia-hpc (for
nvfortran
)
- gcc (for
- version: Version of the compiler toolchain. See runner compatibility charts below.
The action sets the following outputs:
fc
: Fortran compiler executable, e.g.gfortran
cc
: C compiler executable, e.g.gcc
cxx
: C++ compiler executable, e.g.g++
C/C++ compilers of the same toolchain/version are provided where possible, otherwise (if a standalone Fortran compiler is selected) defaulting to the preinstalled GCC. While this action attempts to guarantee Fortran compiler compatibility with all supported platform/toolchain/version combinations, no corresponding guarantee is made with regard to C/C++ compilers — use at your own risk.
The same values are also set as environment variables:
FC
CC
CXX
Corresponding FPM environment variables are also set:
FPM_FC
FPM_CC
FPM_CXX
These are made available to subsequent workflow steps via the GITHUB_ENV
environment file mechanism.
Toolchain support varies across GitHub-hosted runner images.

Note: Intel's ifx
compiler is not supported on macOS, so the intel
option redirects to intel-classic
(ifort
).
