## Compilation and installation
The simplest way of installing GF from source is with the command:
The simplest way of installing GF is with the command:
```
cabal install
```
or:
```
stack install
```
Note that if you are unlucky to have Cabal 3.0 or later, then it uses
the so-called Nix style commands. Using those for GF development is
a pain. Every time when you change something in the source code, Cabal
will generate a new folder for GF to look for the GF libraries and
the GF cloud. Either reinstall everything with every change in the
compiler, or be sane and stop using cabal-install. Instead you can do:
```
runghc Setup.hs configure
runghc Setup.hs build
sudo runghc Setup.hs install
```
The script will install the GF dependencies globally. The only solution
to the Nix madness that I found is radical:
"No person, no problem" (Нет человека – нет проблемы).

# GF Core releases
**Note:**
The RGL is now released completely separately from GF Core.
See the [RGL's RELEASE.md](https://github.com/GrammaticalFramework/gf-rgl/blob/master/RELEASE.md).
## Creating a new release
### 1. Prepare the repository
**Web pages**
1. Create `download/index-X.Y.md` with installation instructions.
2. Create `download/release-X.Y.md` with changelog information.
3. Update `download/index.html` to redirect to the new version.
4. Add announcement in news section in `index.html`.
**Version numbers**
1. Update version number in `gf.cabal` (ommitting `-git` suffix).
2. Add a new line in `debian/changelog`.
### 2. Create GitHub release
1. When the above changes are committed to the `master` branch in the repository
and pushed, check that all CI workflows are successful (fixing as necessary):
- <https://github.com/GrammaticalFramework/gf-core/actions>
- <https://travis-ci.org/github/GrammaticalFramework/gf-core>
2. Create a GitHub release [here](https://github.com/GrammaticalFramework/gf-core/releases/new):
- Tag version format `RELEASE-X.Y`
- Title: "GF X.Y"
- Description: mention major changes since last release
3. Publish the release to trigger the building of the binary packages (below).
### 3. Binary packages
The binaries will be built automatically by GitHub Actions when the release is created,
but the generated _artifacts_ must be manually attached to the release as _assets_.
1. Go to the [actions page](https://github.com/GrammaticalFramework/gf-core/actions) and click "Build Binary Packages" under _Workflows_.
2. Choose the workflow run corresponding to the newly created release.
3. Download the artifacts locally. Extract the Ubuntu and macOS ones to get the `.deb` and `.pkg` files.
4. Go back to the [releases page](https://github.com/GrammaticalFramework/gf-core/releases) and click to edit the release information.
5. Add the downloaded artifacts as release assets, giving them names with format `gf-X.Y-PLATFORM.EXT` (e.g. `gf-3.11-macos.pkg`).
### 4. Upload to Hackage
In order to do this you will need to be added the [GF maintainers](https://hackage.haskell.org/package/gf/maintainers/) on Hackage.
1. Run `stack sdist --test-tarball` and address any issues.
2. Upload the package, either:
1. **Manually**: visit <https://hackage.haskell.org/upload> and upload the file generated by the previous command.
2. **via Stack**: `stack upload . --candidate`
3. After testing the candidate, publish it:
1. **Manually**: visit <https://hackage.haskell.org/package/gf-X.Y.Z/candidate/publish>
1. **via Stack**: `stack upload .`
4. If the documentation-building fails on the Hackage server, do:
```
cabal v2-haddock --builddir=dist/docs --haddock-for-hackage --enable-doc
cabal upload --documentation dist/docs/*-docs.tar.gz
```
## Miscellaneous
### What is the tag `GF-3.10`?
For GF 3.10, the Core and RGL repositories had already been separated, however
the binary packages still included the RGL. `GF-3.10` is a tag that was created
in both repositories ([gf-core](https://github.com/GrammaticalFramework/gf-core/releases/tag/GF-3.10) and [gf-rgl](https://github.com/GrammaticalFramework/gf-rgl/releases/tag/GF-3.10)) to indicate which versions of each went into the binaries.

## unsupported token gluing `foo + bar`
There was a problem in an expression using +, e.g. `foo + bar`.
This can be due to two causes, check which one applies in your case.
1. You are trying to use + on runtime arguments. Even if you are using
`foo + bar` in an oper, make sure that the oper isn't called in a
linearization that takes arguments. Both of the following are illegal:
lin Test foo bar = foo.s + bar.s -- explicit + in a lin
lin Test foo bar = opWithPlus foo bar -- the oper uses +
2. One of the arguments in `foo + bar` is a bound variable
from pattern matching a string, but the cases are non-exhaustive.
Example:
case "test" of {
x + "a" => x + "b" -- no applicable case for "test", so x = ???
} ;
You can fix this by adding a catch-all case in the end:
{ x + "a" => x + "b" ;
_ => "default case" } ;
3. If neither applies to your problem, submit a bug report and we
will update the error message and this documentation.

GF Developer's Guide: Old installation instructions with Cabal
This page contains the old installation instructions from the [Developer's Guide ../doc/gf-developers.html].
We recommend Stack as a primary installation method, because it's easier for a Haskell beginner, and we want to keep the main instructions short.
But if you are an experienced Haskeller and want to keep using Cabal, here are the old instructions using ``cabal install``.
Note that some of these instructions may be outdated. Other parts may still be useful.
== Compilation from source with Cabal ==
The build system of GF is based on //Cabal//, which is part of the
Haskell Platform, so no extra steps are needed to install it. In the simplest
case, all you need to do to compile and install GF, after downloading the
source code as described above, is
```
$ cabal install
```
This will automatically download any additional Haskell libraries needed to
build GF. If this is the first time you use Cabal, you might need to run
``cabal update`` first, to update the list of available libraries.
If you want more control, the process can also be split up into the usual
//configure//, //build// and //install// steps.
=== Configure ===
During the configuration phase Cabal will check that you have all
necessary tools and libraries needed for GF. The configuration is
started by the command:
```
$ cabal configure
```
If you don't see any error message from the above command then you
have everything that is needed for GF. You can also add the option
``-v`` to see more details about the configuration.
You can use ``cabal configure --help`` to get a list of configuration options.
=== Build ===
The build phase does two things. First it builds the GF compiler from
the Haskell source code and after that it builds the GF Resource Grammar
Library using the already build compiler. The simplest command is:
```
$ cabal build
```
Again you can add the option ``-v`` if you want to see more details.
==== Parallel builds ====
If you have Cabal>=1.20 you can enable parallel compilation by using
```
$ cabal build -j
```
or by putting a line
```
jobs: $ncpus
```
in your ``.cabal/config`` file. Cabal
will pass this option to GHC when building the GF compiler, if you
have GHC>=7.8.
Cabal also passes ``-j`` to GF to enable parallel compilation of the
Resource Grammar Library. This is done unconditionally to avoid
causing problems for developers with Cabal<1.20. You can disable this
by editing the last few lines in ``WebSetup.hs``.
=== Install ===
After you have compiled GF you need to install the executable and libraries
to make the system usable.
```
$ cabal copy
$ cabal register
```
This command installs the GF compiler for a single user, in the standard
place used by Cabal.
On Linux and Mac this could be ``$HOME/.cabal/bin``.
On Mac it could also be ``$HOME/Library/Haskell/bin``.
On Windows this is ``C:\Program Files\Haskell\bin``.
The compiled GF Resource Grammar Library will be installed
under the same prefix, e.g. in
``$HOME/.cabal/share/gf-3.3.3/lib`` on Linux and
in ``C:\Program Files\Haskell\gf-3.3.3\lib`` on Windows.
If you want to install in some other place then use the ``--prefix``
option during the configuration phase.
=== Clean ===
Sometimes you want to clean up the compilation and start again from clean
sources. Use the clean command for this purpose:
```
$ cabal clean
```
%=== SDist ===
%
%You can use the command:
%
%% This does *NOT* include everything that is needed // TH 2012-08-06
%```
%$ cabal sdist
%```
%
%to prepare archive with all source codes needed to compile GF.
=== Known problems with Cabal ===
Some versions of Cabal (at least version 1.16) seem to have a bug that can
cause the following error:
```
Configuring gf-3.x...
setup: Distribution/Simple/PackageIndex.hs:124:8-13: Assertion failed
```
The exact cause of this problem is unclear, but it seems to happen
during the configure phase if the same version of GF is already installed,
so a workaround is to remove the existing installation with
```
ghc-pkg unregister gf
```
You can check with ``ghc-pkg list gf`` that it is gone.
== Compilation with make ==
If you feel more comfortable with Makefiles then there is a thin Makefile
wrapper arround Cabal for you. If you just type:
```
$ make
```
the configuration phase will be run automatically if needed and after that
the sources will be compiled.
%% cabal build rgl-none does not work with recent versions of Cabal
%If you don't want to compile the resource library
%every time then you can use:
%```
%$ make gf
%```
For installation use:
```
$ make install
```
For cleaning:
```
$ make clean
```
%and to build source distribution archive run:
%```
%$ make sdist
%```
== Partial builds of RGL ==
**NOTE**: The following doesn't work with recent versions of ``cabal``. //(This comment was left in 2015, so make your own conclusions.)//
%% // TH 2015-06-22
%Sometimes you just want to work on the GF compiler and don't want to
%recompile the resource library after each change. In this case use
%this extended command:
%```
%$ cabal build rgl-none
%```
The resource grammar library can be compiled in two modes: with present
tense only and with all tenses. By default it is compiled with all
tenses. If you want to use the library with only present tense you can
compile it in this special mode with the command:
```
$ cabal build present
```
You could also control which languages you want to be recompiled by
adding the option ``langs=list``. For example the following command
will compile only the English and the Swedish language:
```
$ cabal build langs=Eng,Swe
```

== Setting up your system for building GF ==
To build GF from source you need to install some tools on your
system: the Haskell build tool //Stack//, the version control software //Git// and the //Haskeline// library.

%**On Linux** the best option is to install the tools via the standard

**On Linux** the best option is to install the tools via the standard

in Ubuntu or the corresponding tool in other popular Linux distributions.
Or, from a Terminal window, the following command should be enough:
%**On Mac OS and Windows**, the tools can be downloaded from their respective
%web sites, as described below.
=== Stack ===
The primary installation method is via //Stack//.
(You can also use Cabal, but we recommend Stack to those who are new to Haskell.)
To install Stack:
- **On Linux and Mac OS**, do either
``$ curl -sSL https://get.haskellstack.org/ | sh``
or
``$ wget -qO- https://get.haskellstack.org/ | sh``
- On Ubuntu: ``sudo apt-get install haskell-platform git libghc6-haskeline-dev``
- On Fedora: ``sudo dnf install haskell-platform git ghc-haskeline-devel``
- **On other operating systems**, see the [installation guide https://docs.haskellstack.org/en/stable/install_and_upgrade].
**On Mac OS and Windows**, the tools can be downloaded from their respective
web sites, as described below.
=== The Haskell Platform ===
%If you already have Stack installed, upgrade it to the latest version by running: ``stack upgrade``
GF is written in Haskell, so first of all you need
the //Haskell Platform//, e.g. version 8.0.2 or 7.10.3. Downloads
and installation instructions are available from here:
http://hackage.haskell.org/platform/
Once you have installed the Haskell Platform, open a terminal
(Command Prompt on Windows) and try to execute the following command:
```
$ ghc --version
```
This command should show you which version of GHC you have. If the installation
of the Haskell Platform was successful you should see a message like:
```
The Glorious Glasgow Haskell Compilation System, version 8.0.2
```
Other required tools included in the Haskell Platform are
[Cabal http://www.haskell.org/cabal/],
[Alex http://www.haskell.org/alex/]
and
[Happy http://www.haskell.org/happy/].
=== Git ===
To get the GF source code, you also need //Git//, a distributed version control system.
To get the GF source code, you also need //Git//.
//Git// is a distributed version control system, see
https://git-scm.com/downloads for more information.
- **On Linux**, the best option is to install the tools via the standard
software distribution channels:
- On Ubuntu: ``sudo apt-get install git-all``
- On Fedora: ``sudo dnf install git-all``
- **On other operating systems**, see
https://git-scm.com/book/en/v2/Getting-Started-Installing-Git for installation.
=== Haskeline ===
=== The haskeline library ===
GF uses //haskeline// to enable command line editing in the GF shell.
This should work automatically on Mac OS and Windows, but on Linux one
extra step is needed to make sure the C libraries (terminfo)
required by //haskeline// are installed. Here is one way to do this:
- **On Mac OS and Windows**, this should work automatically.

== Getting the source ==[getting-source]
== Getting the source ==
Once you have all tools in place you can get the GF source code from
[GitHub https://github.com/GrammaticalFramework/]:
Once you have all tools in place you can get the GF source code. If you
just want to compile and use GF then it is enough to have read-only
access. It is also possible to make changes in the source code but if you
want these changes to be applied back to the main source repository you will
have to send the changes to us. If you plan to work continuously on
GF then you should consider getting read-write access.
- https://github.com/GrammaticalFramework/gf-core for the GF compiler
- https://github.com/GrammaticalFramework/gf-rgl for the Resource Grammar Library
=== Read-only access ===
==== Getting a fresh copy for read-only access ====
=== Read-only access: clone the main repository ===
If you only want to compile and use GF, you can just clone the repositories as follows:
Anyone can get the latest development version of GF by running:
```
$ git clone https://github.com/GrammaticalFramework/gf-core.git
$ git clone https://github.com/GrammaticalFramework/gf-rgl.git
$ git clone https://github.com/GrammaticalFramework/gf-core.git
$ git clone https://github.com/GrammaticalFramework/gf-rgl.git
```
To get new updates, run the following anywhere in your local copy of the repository:
This will create directories ``gf-core`` and ``gf-rgl`` in the current directory.
==== Updating your copy ====
To get all new patches from each repo:
```
$ git pull
```
This can be done anywhere in your local repository.
==== Recording local changes ====[record]
Since every copy is a repository, you can have local version control
of your changes.
If you have added files, you first need to tell your local repository to
keep them under revision control:
```
$ git pull
$ git add file1 file2 ...
```
=== Contribute your changes: fork the main repository ===
If you want the possibility to contribute your changes,
you should create your own fork, do your changes there,
and then send a pull request to the main repository.
+ **Creating and cloning a fork —**
See GitHub documentation for instructions how to [create your own fork https://docs.github.com/en/get-started/quickstart/fork-a-repo]
of the repository. Once you've done it, clone the fork to your local computer.
To record changes, use:
```
$ git clone https://github.com/<YOUR_USERNAME>/gf-core.git
$ git commit file1 file2 ...
```
+ **Updating your copy —**
Once you have cloned your fork, you need to set up the main repository as a remote:
This creates a patch against the previous version and stores it in your
local repository. You can record any number of changes before
pushing them to the main repo. In fact, you don't have to push them at
all if you want to keep the changes only in your local repo.
Instead of enumerating all modified files on the command line,
you can use the flag ``-a`` to automatically record //all// modified
files. You still need to use ``git add`` to add new files.
=== Read-write access ===
If you are a member of the GF project on GitHub, you can push your
changes directly to the GF git repository on GitHub.
```
$ git remote add upstream https://github.com/GrammaticalFramework/gf-core.git
$ git push
```
Then you can get the latest updates by running the following:
It is also possible for anyone else to contribute by
```
$ git pull upstream master
```
+ **Recording local changes —**
See Git tutorial on how to [record and push your changes https://git-scm.com/book/en/v2/Git-Basics-Recording-Changes-to-the-Repository] to your fork.
+ **Pull request —**
When you want to contribute your changes to the main gf-core repository,
[create a pull request https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request]
from your fork.
- creating a fork of the GF repository on GitHub,
- working with local clone of the fork (obtained with ``git clone``),
- pushing changes to the fork,
- and finally sending a pull request.
If you want to contribute to the RGL as well, do the same process for the RGL repository.
== Compilation from source with Cabal ==
== Compilation from source ==
By now you should have installed Stack and Haskeline, and cloned the Git repository on your own computer, in a directory called ``gf-core``.
=== Primary recommendation: use Stack ===
Open a terminal, go to the top directory (``gf-core``), and type the following command.
```
$ stack install
```
It will install GF and all necessary tools and libraries to do that.
=== Alternative: use Cabal ===
You can also install GF using Cabal, if you prefer Cabal to Stack. In that case, you may need to install some prerequisites yourself.
The actual installation process is similar to Stack: open a terminal, go to the top directory (``gf-core``), and type the following command.
The build system of GF is based on //Cabal//, which is part of the
Haskell Platform, so no extra steps are needed to install it. In the simplest
case, all you need to do to compile and install GF, after downloading the
source code as described above, is
```
$ cabal install
```
//The old (potentially outdated) instructions for Cabal are moved to a [separate page ../doc/gf-developers-old-cabal.html]. If you run into trouble with ``cabal install``, you may want to take a look.//
This will automatically download any additional Haskell libraries needed to
build GF. If this is the first time you use Cabal, you might need to run
``cabal update`` first, to update the list of available libraries.
== Compiling GF with C runtime system support ==
If you want more control, the process can also be split up into the usual
//configure//, //build// and //install// steps.
The C runtime system is a separate implementation of the PGF runtime services.
=== Configure ===
During the configuration phase Cabal will check that you have all
necessary tools and libraries needed for GF. The configuration is
started by the command:
```
$ cabal configure
```
If you don't see any error message from the above command then you
have everything that is needed for GF. You can also add the option
``-v`` to see more details about the configuration.
You can use ``cabal configure --help`` to get a list of configuration options.
=== Build ===
The build phase does two things. First it builds the GF compiler from
the Haskell source code and after that it builds the GF Resource Grammar
Library using the already build compiler. The simplest command is:
```
$ cabal build
```
Again you can add the option ``-v`` if you want to see more details.
==== Parallel builds ====
If you have Cabal>=1.20 you can enable parallel compilation by using
```
$ cabal build -j
```
or by putting a line
```
jobs: $ncpus
```
in your ``.cabal/config`` file. Cabal
will pass this option to GHC when building the GF compiler, if you
have GHC>=7.8.
Cabal also passes ``-j`` to GF to enable parallel compilation of the
Resource Grammar Library. This is done unconditionally to avoid
causing problems for developers with Cabal<1.20. You can disable this
by editing the last few lines in ``WebSetup.hs``.
==== Partial builds ====
**NOTE**: The following doesn't work with recent versions of ``cabal``.
%% // TH 2015-06-22
Sometimes you just want to work on the GF compiler and don't want to
recompile the resource library after each change. In this case use
this extended command:
```
$ cabal build rgl-none
```
The resource library could also be compiled in two modes: with present
tense only and with all tenses. By default it is compiled with all
tenses. If you want to use the library with only present tense you can
compile it in this special mode with the command:
```
$ cabal build present
```
You could also control which languages you want to be recompiled by
adding the option ``langs=list``. For example the following command
will compile only the English and the Swedish language:
```
$ cabal build langs=Eng,Swe
```
=== Install ===
After you have compiled GF you need to install the executable and libraries
to make the system usable.
```
$ cabal copy
$ cabal register
```
This command installs the GF compiler for a single user, in the standard
place used by Cabal.
On Linux and Mac this could be ``$HOME/.cabal/bin``.
On Mac it could also be ``$HOME/Library/Haskell/bin``.
On Windows this is ``C:\Program Files\Haskell\bin``.
The compiled GF Resource Grammar Library will be installed
under the same prefix, e.g. in
``$HOME/.cabal/share/gf-3.3.3/lib`` on Linux and
in ``C:\Program Files\Haskell\gf-3.3.3\lib`` on Windows.
If you want to install in some other place then use the ``--prefix``
option during the configuration phase.
=== Clean ===
Sometimes you want to clean up the compilation and start again from clean
sources. Use the clean command for this purpose:
```
$ cabal clean
```
%=== SDist ===
%
%You can use the command:
%
%% This does *NOT* include everything that is needed // TH 2012-08-06
%```
%$ cabal sdist
%```
%
%to prepare archive with all source codes needed to compile GF.
=== Known problems with Cabal ===
Some versions of Cabal (at least version 1.16) seem to have a bug that can
cause the following error:
```
Configuring gf-3.x...
setup: Distribution/Simple/PackageIndex.hs:124:8-13: Assertion failed
```
The exact cause of this problem is unclear, but it seems to happen
during the configure phase if the same version of GF is already installed,
so a workaround is to remove the existing installation with
```
ghc-pkg unregister gf
```
You can check with ``ghc-pkg list gf`` that it is gone.
== Compilation with make ==
If you feel more comfortable with Makefiles then there is a thin Makefile
wrapper arround Cabal for you. If you just type:
```
$ make
```
the configuration phase will be run automatically if needed and after that
the sources will be compiled.
%% cabal build rgl-none does not work with recent versions of Cabal
%If you don't want to compile the resource library
%every time then you can use:
%```
%$ make gf
%```
For installation use:
```
$ make install
```
For cleaning:
```
$ make clean
```
%and to build source distribution archive run:
%```
%$ make sdist
%```
== Compiling GF with C run-time system support ==
The C run-time system is a separate implementation of the PGF run-time services.
It makes it possible to work with very large, ambiguous grammars, using
probabilistic models to obtain probable parses. The C runtime system might
also be easier to use than the Haskell runtime system on certain platforms,
probabilistic models to obtain probable parses. The C run-time system might
also be easier to use than the Haskell run-time system on certain platforms,
e.g. Android and iOS.
To install the C runtime system, go to the ``src/runtime/c`` directory.
To install the C run-time system, go to the ``src/runtime/c`` directory
%and follow the instructions in the ``INSTALL`` file.
and use the ``install.sh`` script:
```
bash setup.sh configure
bash setup.sh build
bash setup.sh install
```
This will install
the C header files and libraries need to write C programs that use PGF grammars.
Some example C programs are included in the ``utils`` subdirectory, e.g.
``pgf-translate.c``.
- **On Linux and Mac OS —**
You should have autoconf, automake, libtool and make.
If you are missing some of them, follow the
instructions in the [INSTALL https://github.com/GrammaticalFramework/gf-core/blob/master/src/runtime/c/INSTALL] file.
Once you have the required libraries, the easiest way to install the C runtime is to use the ``install.sh`` script. Just type
``$ bash install.sh``
This will install the C header files and libraries need to write C programs
that use PGF grammars.
% If this doesn't work for you, follow the manual instructions in the [INSTALL https://github.com/GrammaticalFramework/gf-core/blob/master/src/runtime/c/INSTALL] file under your operating system.
- **On other operating systems —** Follow the instructions in the
[INSTALL https://github.com/GrammaticalFramework/gf-core/blob/master/src/runtime/c/INSTALL] file under your operating system.
Depending on what you want to do with the C runtime, you can follow one or more of the following steps.
=== Use the C runtime from another programming language ===[bindings]
% **If you just want to use the C runtime from Python, Java, or Haskell, you don't need to change your GF installation.**
- **What —**
This is the most common use case for the C runtime: compile
your GF grammars into PGF with the standard GF executable,
and manipulate the PGFs from another programming language,
using the bindings to the C runtime.
- **How —**
The Python, Java and Haskell bindings are found in the
``src/runtime/{python,java,haskell-bind}`` directories,
respecively. Compile them by following the instructions
in the ``INSTALL`` or ``README`` files in those directories.
The Python library can also be installed from PyPI using ``pip install pgf``.
//If you are on Mac and get an error about ``clang`` version, you can try some of [these solutions https://stackoverflow.com/questions/63972113/big-sur-clang-invalid-version-error-due-to-macosx-deployment-target]—but be careful before removing any existing installations.//
=== Use GF shell with C runtime support ===
- **What —**
If you want to use the GF shell with C runtime functionalities, then you need to (re)compile GF with special flags.
The GF shell can be started with ``gf -cshell`` or ``gf -crun`` to use
the C run-time system instead of the Haskell run-time system.
Only limited functionality is available when running the shell in these
modes (use the ``help`` command in the shell for details).
(Re)compiling your GF with these flags will also give you
Haskell bindings to the C runtime, as a library called ``PGF2``,
but if you want Python or Java bindings, you need to do [the previous step #bindings].
% ``PGF2``: a module to import in Haskell programs, providing a binding to the C run-time system.
- **How —**
If you use cabal, run the following command:
When the C run-time system is installed, you can install GF with C run-time
support by doing
```
cabal install -fc-runtime
cabal install -fserver -fc-runtime
```
from the top directory. This give you three new things:
from the top directory (``gf-core``).
- ``PGF2``: a module to import in Haskell programs, providing a binding to
the C run-time system.
If you use stack, uncomment the following lines in the ``stack.yaml`` file:
- The GF shell can be started with ``gf -cshell`` or ``gf -crun`` to use
the C run-time system instead of the Haskell run-time system.
Only limited functionality is available when running the shell in these
modes (use the ``help`` command in the shell for details).
```
flags:
gf:
c-runtime: true
extra-lib-dirs:
- /usr/local/lib
```
and then run ``stack install`` from the top directory (``gf-core``).
- ``gf -server`` mode is extended with new requests to call the C run-time
system, e.g. ``c-parse``, ``c-linearize`` and ``c-translate``.
//If you get an "``error while loading shared libraries``" when trying to run GF with C runtime, remember to declare your ``LD_LIBRARY_PATH``.//
//Add ``export LD_LIBRARY_PATH="/usr/local/lib"`` to either your ``.bashrc`` or ``.profile``. You should now be able to start GF with C runtime.//
=== Use GF server mode with C runtime ===
- **What —**
With this feature, ``gf -server`` mode is extended with new requests to call the C run-time
system, e.g. ``c-parse``, ``c-linearize`` and ``c-translate``.
- **How —**
If you use cabal, run the following command:
```
cabal install -fc-runtime -fserver
```
from the top directory.
If you use stack, add the following lines in the ``stack.yaml`` file:
```
flags:
gf:
c-runtime: true
server: true
extra-lib-dirs:
- /usr/local/lib
```
and then run ``stack install``, also from the top directory.
=== Python and Java bindings ===
The C run-time system can also be used from Python and Java. Python and Java
bindings are found in the ``src/runtime/python`` and ``src/runtime/java``
directories, respecively. Compile them by following the instructions in
the ``INSTALL`` files in those directories.
== Compilation of RGL ==
As of 2018-07-26, the RGL is distributed separately from the GF compiler and runtimes.
To get the source, follow the previous instructions on [how to clone a repository with Git #getting-source].
After cloning the RGL, you should have a directory named ``gf-rgl`` on your computer.
=== Simple ===
To install the RGL, you can use the following commands from within the ``gf-rgl`` repository:

https://github.com/GrammaticalFramework/gf-core/actions/workflows/build-binary-packages.yml
This was tested on Ubuntu 14.04 for the release of GF 3.6, and the

For the release of GF 3.7, we generated ``.deb`` packages on Ubuntu 15.04 and
tested them on Ubuntu 12.04 and 14.04.
Under Ubuntu, Haskell executables are statically linked against other Haskell
libraries, so the .deb packages are fairly self-contained.

It involves using the cabal-rpm tool,
```
sudo dnf install cabal-rpm
```
and following the Fedora guide
[How to create an RPM package http://fedoraproject.org/wiki/How_to_create_an_RPM_package].
Under Fedora, Haskell executables are dynamically linked against other Haskell
libraries, so ``.rpm`` packages for all Haskell libraries that GF depends on
are required. Most of them are already available in the Fedora distribution,
but a few of them might have to be built and distributed along with
the GF ``.rpm`` package.
When building ``.rpm`` packages for GF 3.4, we also had to build ``.rpm``s for
``fst`` and ``httpd-shed``.
== Running the testsuite ==
**NOTE:** The test suite has not been maintained recently, so expect many
tests to fail.
%% // TH 2012-08-06
GF has testsuite. It is run with the following command:
```
$ cabal test
```
The testsuite architecture for GF is very simple but still very flexible.
GF by itself is an interpreter and could execute commands in batch mode.
This is everything that we need to organize a testsuite. The root of the
testsuite is the ``testsuite/`` directory. It contains subdirectories
which themselves contain GF batch files (with extension ``.gfs``).
The above command searches the subdirectories of the ``testsuite/`` directory
for files with extension ``.gfs`` and when it finds one, it is executed with
the GF interpreter. The output of the script is stored in file with extension ``.out``
and is compared with the content of the corresponding file with extension ``.gold``, if there is one.
testsuite is the testsuite/ directory. It contains subdirectories which
themself contain GF batch files (with extension .gfs). The above command
searches the subdirectories of the testsuite/ directory for files with extension
.gfs and when it finds one it is executed with the GF interpreter.
The output of the script is stored in file with extension .out and is compared
with the content of the corresponding file with extension .gold, if there is one.
If the contents are identical the command reports that the test was passed successfully.
Otherwise the test had failed.
Every time when you make some changes to GF that have to be tested,
instead of writing the commands by hand in the GF shell, add them to one ``.gfs``
file in the testsuite subdirectory where its ``.gf`` file resides and run the test.
In this way you can use the same test later and we will be sure that we will not
accidentally break your code later.
**Test Outcome - Passed:** If the contents of the files with the ``.out`` extension
are identical to their correspondingly-named files with the extension ``.gold``,
the command will report that the tests passed successfully, e.g.
Every time when you make some changes to GF that have to be tested, instead of
writing the commands by hand in the GF shell, add them to one .gfs file in the testsuite
and run the test. In this way you can use the same test later and we will be sure
that we will not incidentaly break your code later.
If you don't want to run the whole testsuite you can write the path to the subdirectory
in which you are interested. For example:
```
Running 1 test suites...
Test suite gf-tests: RUNNING...
Test suite gf-tests: PASS
1 of 1 test suites (1 of 1 test cases) passed.
$ cabal test testsuite/compiler
```
**Test Outcome - Failed:** If there is a contents mismatch between the files
with the ``.out`` extension and their corresponding files with the extension ``.gold``,
the test diagnostics will show a fail and the areas that failed. e.g.
```
testsuite/compiler/compute/Records.gfs: OK
testsuite/compiler/compute/Variants.gfs: FAIL
testsuite/compiler/params/params.gfs: OK
Test suite gf-tests: FAIL
0 of 1 test suites (0 of 1 test cases) passed.
```
The fail results overview is available in gf-tests.html which shows 4 columns:
+ __Results__ - only areas that fail will appear. (Note: There are 3 failures in the gf-tests.html which are labelled as (expected). These failures should be ignored.)
+ __Input__ - which is the test written in the .gfs file
+ __Gold__ - the expected output from running the test set out in the .gfs file. This column refers to the contents from the .gold extension files.
+ __Output__ - This column refers to the contents from the .out extension files which are generated as test output.
After fixing the areas which fail, rerun the test command. Repeat the entire process of fix-and-test until the test suite passes before submitting a pull request to include your changes.

title: Grammatical Framework Download and Installation
date: 25 July 2021
---
**GF 3.11** was released on 25 July 2021.
What's new? See the [release notes](release-3.11.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/3.11)
#### Debian/Ubuntu
There are two versions: `gf-3.11-ubuntu-18.04.deb` for Ubuntu 18.04 (Cosmic), and `gf-3.11-ubuntu-20.04.deb` for Ubuntu 20.04 (Focal).
To install the package use:
```
sudo apt-get install ./gf-3.11-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-3.11
```
### 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).

If this doesn't work, you will need to install the C runtime manually; see the instructions [here](https://www.grammaticalframework.org/doc/gf-developers.html#toc12).

## 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.
For more information, see [Using GF on Windows](https://www.grammaticalframework.org/~inari/gf-windows.html) (latest updated for Windows 10).
## 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).

This assumes that you already have GF installed.
For more details about building the RGL, see the [RGL README](https://github.com/GrammaticalFramework/gf-rgl/blob/master/README.md).
## 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 OSX (with Windows missing so far), which
include the C runtime and a 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.
