title: Grammatical Framework Download and Installation
date: 2 August 2025
---
**GF 3.12** was released on 2 August 2025.
What's new? See the [release notes](release-3.12.html).
#### Note: GF core and the RGL
The following instructions explain how to install **GF core**, i.e. the compiler, shell and run-time systems.
Obtaining the **Resource Grammar Library (RGL)** is done separately; see the section at the bottom of this page.
---
## Installing from a binary package
Binary packages are available for Debian/Ubuntu, macOS, and Windows and include:
- GF shell and grammar compiler
- `gf -server` mode
- C run-time system
- Java & Python bindings to the C run-time system
Unlike in previous versions, the binaries **do not** include the RGL.
[Binary packages on GitHub](https://github.com/GrammaticalFramework/gf-core/releases/tag/3.12)
#### Debian/Ubuntu
There are two versions: `gf-3.12-ubuntu-18.04.deb` for Ubuntu 18.04 (Cosmic), and `gf-3.12-ubuntu-20.04.deb` for Ubuntu 20.04 (Focal).
To install the package use:
```
sudo apt-get install ./gf-3.12-ubuntu-*.deb
```
<!-- The Ubuntu `.deb` packages should work on Ubuntu 16.04, 18.04 and similar Linux distributions. -->
#### macOS
To install the package, just double-click it and follow the installer instructions.
The packages should work on at least Catalina and Big Sur.
#### Windows
To install the package, unpack it anywhere.
You will probably need to update the `PATH` environment variable to include your chosen install location.
For more information, see [Using GF on Windows](https://www.grammaticalframework.org/~inari/gf-windows.html) (latest updated for Windows 10).
## Installing from Hackage
_Instructions applicable for macOS, Linux, and WSL2 on Windows._
[GF is on Hackage](http://hackage.haskell.org/package/gf), so under
normal circumstances the procedure is fairly simple:
```
cabal update
cabal install gf-3.12
```
### Notes
**GHC version**
The GF source code is known to be compilable with GHC versions 7.10 through to 8.10.
**Obtaining Haskell**
There are various ways of obtaining Haskell, including:
- ghcup
1. Install from https://www.haskell.org/ghcup/
2. `ghcup install ghc 8.10.4`
3. `ghcup set ghc 8.10.4`
- Haskell Platform https://www.haskell.org/platform/
- Stack https://haskellstack.org/
**Installation location**
The above steps install GF for a single user.
The executables are put in `$HOME/.cabal/bin` (or on macOS in `$HOME/Library/Haskell/bin`),
so you might want to add this directory to your path (in `.bash_profile` or similar):
```
PATH=$HOME/.cabal/bin:$PATH
```
**Haskeline**
GF uses [`haskeline`](http://hackage.haskell.org/package/haskeline), which
on Linux depends on some non-Haskell libraries that won't be installed
automatically by Cabal, and therefore need to be installed manually.
Here is one way to do this:
- On Ubuntu: `sudo apt-get install libghc-haskeline-dev`
- On Fedora: `sudo dnf install ghc-haskeline-devel`
## Installing from source code
**Obtaining**
To obtain the source code for the **release**,
download it from [GitHub](https://github.com/GrammaticalFramework/gf-core/releases).
Alternatively, to obtain the **latest version** of the source code:
1. If you haven't already, clone the repository with:
```
git clone https://github.com/GrammaticalFramework/gf-core.git
```
2. If you've already cloned the repository previously, update with:
```
git pull
```
**Installing**
You can then install with:
```
cabal install
```
or, if you're a Stack user:
```
stack install
```
<!--The above notes for installing from source apply also in these cases.-->
For more info on working with the GF source code, see the
[GF Developers Guide](../doc/gf-developers.html).
For macOS Sequoia, you need to downgrade the LLVM package, see instructions [here](https://github.com/GrammaticalFramework/gf-core/issues/172#issuecomment-2599365457).
## Installing the Python bindings from PyPI
The Python library is available on PyPI as `pgf`, so it can be installed using:
```
pip install pgf
```
We provide binary wheels for Linux and macOS, which include the C runtime and are ready-to-go.
If there is no binary distribution for your platform, this will install the source tarball,
which will attempt to build the binding during installation,
and requires the GF C runtime to be installed on your system.
---
## Installing the RGL from a binary release
Binary releases of the RGL are made available on [GitHub](https://github.com/GrammaticalFramework/gf-rgl/releases).
In general the steps to follow are:
1. Download a binary release and extract it somewhere on your system.
2. Set the environment variable `GF_LIB_PATH` to point to wherever you extracted the RGL.
## Installing the RGL from source
To compile the RGL, you will need to have GF already installed and in your path.
1. Obtain the RGL source code, either by:
- cloning with `git clone https://github.com/GrammaticalFramework/gf-rgl.git`
- downloading a source archive [here](https://github.com/GrammaticalFramework/gf-rgl/archive/master.zip)
2. Run `make` in the source code folder.
For more options, see the [RGL README](https://github.com/GrammaticalFramework/gf-rgl/blob/master/README.md).
