To help with Linux packages, please join the F# Core Engineering Group. You can also submit an edit to this page.

Option 1: Use the F# Debian/Ubuntu packages

F# is available as a Debian package.

It is highly recommended (albeit optional) that you add the Xamarin Mono package repository to your sources to get a much more up-to-date version of the Mono runtime used by F#.

sudo apt-key adv --keyserver --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list

For Ubuntu 12.04 and 12.10 you will need an additional repository as well, see these instrutions. Older F# and Mono packages are available in Debian testing and Ubuntu 14.04 (trusty/universe).

Regardless of which repository source you are using, proceed to install the fsharp & mono packages

sudo apt-get update
sudo apt-get install mono-complete fsharp

This installs fsharpc and fsharpi. If you don’t have access to these repositories, compile from source or see Option 6 below. Once installed, see the Linux and Cross-Platform Development Guide to go further.

Option 2: Build and install the F# runtime, compiler and tools

  1. Get Mono, the cross-platform, open source .NET runtime implementation used by F#. Preferably use a package from your distribution or Xamarin. If this is not possible, install from source by following these instructions.

    Note that if you are installing to a private prefix, follow these instructions and ensure LD_LIBRARY_PATH includes the “lib” directory of that prefix location and PKG_CONFIG_PATH includes the “lib/pkgconfig” directory of that prefix location, e.g.

     export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/user/mono/lib/
     export PKG_CONFIG_PATH=/home/user/mono/lib/pkgconfig/
  2. Build and install the F# Compiler (open edition) from source. If using a VM or other memory-constrained system, be aware that errors during compilation may be due to insufficient memory (in particular error 137).

     sudo apt-get install autoconf libtool pkg-config make git automake
     git clone
     cd fsharp
     ./ --prefix /usr
     sudo make install

    If installing to a different prefix, use the same prefix as for the Mono runtime above.

Once installed, see the Linux and Cross-Platform Development Guide to go further.

Option 3: F# for RHEL, CentOS, Amazon, Fedora w/ puppet/configuration management

To see an example of how to set it up, navigate to, read the README and look inside the run file and the Vagrantfile file. It pulls down all required dependencies and starts vagrant to get you up and running EventStore (as a sample application).

With the epel, eventstore, mono and supervisor puppet module and a reference to packagecloud/haf/oss repository, you can install a full environment and running service in a couple of minutes:

class baseline {
  include ::epel
  include ::packagecloud

  packagecloud::repo { 'haf/oss':
    type => 'rpm',

node default {
  include ::baseline

  class { 'mono':
    require => [

  class { 'supervisor':
    require => [

  include ::eventstore

Option 4: Get F# on Gentoo (Sabayon/Funtoo/Calculate)

From portage tree:

    emerge fsharp

Alternatively there is an overlay available with current versions of various .NET programs, including F#, FAKE, NuGet and others.

  1. Add the “dotnet” overlay from layman. (If you need to set it up, there is a Manual on the Gentoo site.)

    layman -a dotnet 
  2. Now you can build F#.

    emerge fsharp
  3. (Optional) There are emacs mode and monodevelop bindings, you can chose what you want by setting use flags alike in following example:

    USE="+emacs -monodevelop" emerge fsharpbinding

Once installed, see the Linux and Cross-Platform Development Guide to go further.

Option 5: Use a Vagrant VM on Windows

To use F# on Linux VMs on Windows, use F# with Vagrant.

Option 6: Slackware Slackbuild

  1. Get Mono Slackbuild from this page and run :


  2. Get last FSharp Slackbuild from this page and run :
