Package Installation
dpkg
CHICKEN 2.3 (a very old version) is officially included in the Debian 3.1 (Sarge) and 4.0 (Etch) distributions. Newer CHICKEN versions are available via unofficial packages, please see Debian packages.
Fink
Fink users can type the following command in a Terminal:
fink install chicken
This will download, compile and install the latest CHICKEN version.
MacPorts
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.
The MacPorts package is maintained by Arto Bendiken.
pkgsrc
Users of pkgsrc can use the lang/chicken package from pkgsrc.org to install the latest stable release.
pkgsrc is a cross-platform packaging system, which works 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.
Portage
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.
RPM
Chicken does not currently have an RPM package.
Manual Installation
Manual installation is your best bet for getting the latest and greatest version of Chicken.
Stable Releases
To install a stable release of Chicken, head to the releases page and download a tarball. Check out the README file for installation instructions.
Development Version
The current Chicken development version can be accessed through the Subversion revision control system, like this:
svn co https://galinha.ucpel.tche.br/svn/chicken-eggs/chicken/trunk
(username: anonymous, password: <none>)
Note: You must have Chicken installed before you can compile Chicken from subversion, as a substantial portion of Chicken is written in Chicken itself. To do this, first download and install Chicken from the releases page, then use that to compile and install the code from Subversion.
