An easy Windows installer and launcher for GFortran and the Fortran Package Manager
Download the latest installer from the Releases Page
Note: the installer takes a little while to startup due to it size, please be patient.
- Installs locally, no adminstrator account required
- Optionally add everything to the PATH for the local user
- Includes:
- GCC-GFortran 12.2.0
- Fortran Package Manager v0.8.2
- Git for Windows v2.35.2 (needed for fpm)
- OpenBLAS (BLAS/LAPACK) v0.3.20-1
- GNU make v4.3
- Extra utility commands
intel-setvars
to initialise the Intel OneAPI environment (if installed)setup-stdlib
to build and install the latest version of the Fortran Standard Library
No, the installer will install files to the AppData
directory for the current user (C:\Users\<user>\AppData\Local
).
The 'Add to path' installer option will update the Windows PATH variable for the local user
so that all the installed components are available to other applications.
This means that you can call gfortran
or fpm from any command window or code editor/IDE.
Alternatively, you may create an 'isolated' installation by unchecking the 'Add to path' option when installing. In this case, the installed programs are only made available when you use the 'Quickstart Fortran' command line shortcut added to the desktop and start menu.
Yes. The installation adds a helper command intel-setvars
to setup the intel environment
(this must be called each time you open a new command window.).
The helper script assumes OneAPI is installed at C:\Program Files (x86)\Intel\oneAPI
.
After setting up the intel environment, you may use ifort
with fpm by appending
--compiler ifort
to each fpm command or by setting the environment variable:
> set FPM_COMPILER=ifort
First, run the installer, making sure that GFortran, fpm and Git are selected. After install,
open up the commmand window using the Quickstart Fortran
shortcut on the desktop or in the start menu.
At the command window type setup-stdlib
and press ENTER.
This will fetch the latest version of stdlib
and install it to the local GFortran installation.
Note: The setup-stdlib
script only works with the GFortran installation provided with this installer - it cannot
currently detect existing GFortran or Intel fortran installations.
The optimized OpenBLAS library is included with the GCC installation.
Use the link flags -llapack -lblas
or add the following to your fpm.toml
file:
[build]
link = ["lapack", "blas"]
There is an uninstall program which may be launched from the start menu:
Start menu > All programs > Quickstart Fortran > Uninstall
The installer is built using the Nullsoft Scriptable Install System.
See quickstart-fortran-installer.nsi
for the configuration file and
make_installer.yml
for the Github actions workflow.
The GNU Compiler Collection v11.2.0 is sourced from WinLibs based on the MinGW-w64 project linked with MSVCRT.
