Platform packages

This aims to provide a comprehensive listing of all platforms where CHICKEN is available in pre-packaged form (whether as a distribution package or a binary).

To see on which platforms CHICKEN is supported, see portability.

In order to enable software written using CHICKEN to be effectively distributed, it is important that CHICKEN (or at least the CHICKEN libraries) be included in as many of the various packaging systems as possible, so that it can always be relied on as an available dependency.


Arch Linux

 pacman -S chicken

Debian Linux

Users can install CHICKEN on Debian by using apt or aptitude:

# apt install chicken-bin


# aptitude install chicken-bin

Debian page for the CHICKEN source package.

Fedora Linux (and RHEL derivatives, via EPEL)

Fedora officially includes a fairly recent version of CHICKEN. To install, just use yum:

 sudo yum install chicken

There is also an unofficial RPM repository located at home:zilti:chicken with up-to-date Fedora packages.

Ubuntu Linux

Gentoo Linux

Gentoo users can install chicken the normal way:

 emerge -auv chicken

This will download, compile and install the latest version of CHICKEN (if it is not already installed).

CHICKEN's Portage ebuild is maintained by Marijn Schouten.


There is currently one semi-official and one unofficial build of CHICKEN. Both are build on OBS, the openSUSE Build Service.

The semi-official one can be found at devel:languages:misc. The unofficial one is from the user zilti and you can find it at home:zilti:chicken

In order to install CHICKEN from devel:languages:misc, you need something along the lines of:

# zypper addrepo https://download.opensuse.org/repositories/devel:languages:misc/openSUSE_Leap_15.1/devel:languages:misc.repo
# zypper refresh
# zypper install chicken

For a complete set of openSUSE distributions and more installation options you can check the CHICKEN download page at software.opensuse.org



 xbps-install chicken

Embedded Linux


meta-chicken is a layer for Yocto/OpenEmbedded which can be used to cross-compile CHICKEN and eggs.


CHICKEN 5.0.0 is included in the development branch of OpenWRT. If you have the line

 src/gz openwrt_packages http://downloads.openwrt.org/snapshots/packages/.../packages

(note it says 'snapshots' and not 'releases') in the file


you'll be able to install it with opkg as shown below:

 opkg install chicken-scheme-interpreter

For the stable version it would be necessary to compile the sources from this repository (follow the instructions there).


This package consists of the runtime library plus interpreter. The version of CHICKEN is 2.733.

ipkg install http://zedstar.org/ipk/chicken-scheme-interpreter_2.733_armv4t.ipk

Package maintained by john moore.

Maemo 5

Instructions for getting CHICKEN (4.4) and many eggs from a handy optified deb repository are at: http://0xab.com/n900

Package maintained by Andrei Barbu.

Chrome OS

If you have your Chrome OS device in developer mode and have installed Chromebrew you can install it from binaries using:

 crew install chicken

or compile from source using:

 crew install -s chicken

Mac OS X


If you're using MacPorts, installation is very simple. Open the Terminal application and type the following:

 sudo port install chicken

This will download, compile and install the latest CHICKEN version.

Installing the readline egg

You can install the readline egg to get history and tab-completion in csi. See Using the interpreter.

However, you may get errors when compiling the egg. This is because Apple doesn't ship GNU readline with OS X. However, there is an easy fix:

 port install readline

Fixing libchicken.dylib

When using certain extensions (posix is one example), you may come across the following error:

 "dlopen(libchicken.dylib, 9): image not found"

The easiest way to fix this is to add an alias to libchicken.dylib to /usr/local/lib, like so:

 sudo ln -s /opt/local/lib/libchicken.dylib /usr/local/lib/

Another solution is to set the DYLD_LIBRARY_PATH environment variable to the location of libchicken.dylib. However, this will mess up some other programs, as they will look for their libraries in /opt/local/lib as well. One solution is to set up aliases for csi and csc in your bash profile. Add the following two lines to ~/.profile:

 alias csi='DYLD_LIBRARY_PATH=/opt/local/lib csi'
 alias csc='DYLD_LIBRARY_PATH=/opt/local/lib csc'

This will set DYLD_LIBRARY_PATH for csi and csc, but not for other commands.


If you're using Homebrew you can install the formula chicken:

   brew install chicken



For FreeBSD, you can use the lang/chicken5 port to install the latest stable release.


For NetBSD, you can use the lang/chicken package from pkgsrc to install the latest stable release.


For OpenBSD, you can use the lang/chicken package by running the following command as root:

$ pkg_add chicken

DragonFly BSD

For DragonFly BSD, you can use the lang/chicken package from pkgsrc to install the latest stable release.



CHICKEN has been added to the official ports repository and can be installed with the following command:

 haikuporter -i chicken

Other platforms/cross-platform support


For many systems, you can use pkgsrc. This is a cross-platform packaging system, which works on most modern Unix-like operating systems and even on Windows (using Interix/Services for Unix or Cygwin). See this table for the full list of supported platforms.

Microsoft Windows

NOTE: Some users may encounter issues installing eggs on Windows (particularly bind) unless an appropriate C compiler is installed. It is recommended to use mingw-w64 in place of mingw32 as the mingw32 project is no longer as actively maintained.

Chicken on the Chocolatey package manager, most recent pre-packaged version

Installer for Windows, includes the IUP and Canvas Draw eggs preinstalled

Another installer for Windows

If you use cygwin there are up to date packages included for 32 and 64bit versions.

MSYS2 is easy to setup and build Chicken for, and produces native 64 bit Windows binaries.
