Article contents:[[toc:]] [[tags:platforms installation linux bsd mac windows]] There are two ways to install CHICKEN: from a package, or manually. Package installation is probably easier, but manual installation will most likely get you a more current version. Whichever version you choose, you will probably also want to install the readline egg, which will give you more features in the CSI interpreter. == Package Installation === dpkg CHICKEN 4.13 is officially included in Debian buster (stretch has 4.11, jessie has 4.9, bullseye (testing) has 5.2) The compiler can be installed using apt install chicken-bin This will also install the runtime, which is contained in libchicken<number>, where number is the shared object version number (so multiple runtime versions can coexist on the same debian system). === Fink [[http://www.finkproject.org/|Fink]] users can type the following command in a Terminal: fink install chicken This will download, compile and install the latest CHICKEN version. === iPKG iPKG packages are available for the [[http://www.openmoko.com/|OpenMoko]] linux-based mobile phone OS. Note, this build is for phones flashed with 2007.1. To install the interpreter (csi) and runtime library: ipkg install http://wiki.call-cc.org/download/chicken-scheme-interpreter_2.6_armv4t.ipk For 2007.2 builds: ipkg install http://zedstar.org/ipk/2007.2/chicken-scheme-interpreter_2.6_armv4t.ipk Package maintained by [[/users/john moore|john moore]]. === MacPorts If you're using [[http://www.macports.org/|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 [[/users/arto-bendiken|Arto Bendiken]]. ==== Installing the readline egg You can install the readline egg to get history and tab-completion in csi. See [[/manual/Using the interpreter|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. === pkgsrc Users of pkgsrc can use the {{lang/chicken}} package from [[http://www.pkgsrc.org|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 [[http://www.netbsd.org/docs/software/packages.html#platforms|this table]] for the full list of supported platforms. === Portage [[http://www.gentoo.org/|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 [[http://packages.gentoo.org/ebuilds/?chicken-2.6|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|releases]] page and download a tarball. Check out the README file for installation instructions. === Development Version See the [[http://code.call-cc.org]] page for instructions about how to obtain development versions of CHICKEN.
