Debian                                            Apr 26, 2017                                CHICKEN-INSTALL(1)

chicken-install  downloads,  compiles  and  installs a prepackaged extension library from sources.  If no
       extension name is given on the command line, then any existing egg descriptions in the current  directory
       will be executed in unspecified order.

       The program accepts following arguments:

       -h, -help
               Show usage and exit.

       -version
               Show version and exit.

       -v, -verbose
               Print extra information during installation.

       -force  Install without confirmation, even if versions don't match.

       -k, -keep
               Keep temporary files.

       -s, -sudo
               Use an external program to elevate privileges for filesystem operations.  The program defaults to
               sudo(8) but can be overridden with the SUDO environment variable.

       -r, -retrieve
               Just retrieve the egg, don't install it (giving -r more than once implies -recursive).

       -recursive
               If -retrieve is given, also fetch dependencies recursively.

       -dry-run
               Do not build or install, just print the locations of the generated build & install scripts.

       -list-versions
               List available versions for the given eggs.

       -purge  Remove cached files for given eggs (or purge cache completely).

       -host   When cross-compiling, only compile extensions for host.

       -target
               When cross-compiling, only compile extensions for target.

       -test   Run included test cases, if available.

       -n, -no-install
               Do not install the egg, just build it.

       -no-install-dependencies
               Do  not  install  dependencies. Note that this option may result in build failures due to missing
               extension libraries.

       -u, -update-db
               Update export database.

       -repository
               Print path used for egg installation.

       -overridefilename
               Override versions for installed eggs with information from filename.

       -from-listfilename
               Install eggs listed in filename, which has the same format as chicken-status(1)'s  -list  output.
               This option may be given multiple times.

       -cached
               Only install eggs from cache, do not download.

       -feature, -Dname
               Register feature name, usable as a condition in cond-expand clauses.

       Following environment variables change the behaviour of chicken-install:

       CHICKEN_EGG_CACHE           Location where eggs are retrieved and built.

       CHICKEN_INSTALL_REPOSITORY  The  path  where  extension  libraries are installed. Defaults to the package
                                   library      path      selected      during      configuration       (usually
                                   /var/lib/chicken/<binary-version>).

       SUDO                        The  command  to  execute  when  using  -s  flag in command. If not provided,
                                   defaults to sudo(8).

       Install ‘regex’ egg as root user:

             #chicken-installregex

       Install an egg as an normal user but using sudo(8):

             $chicken-install-sregex

       Install an egg as an normal user but  elevating  privileges  with  different  program,  such  as  OpenBSD
       doas(1):

             $SUDO=/usr/bin/doaschicken-install-sregex

       The chicken-install utility exits 0 on success, 2 if the user aborted an operation, 3 if it  was  invoked
       with  no explicitly given egg names and no *.egg files could be found in the current directory, and >0 if
       any other error occurs.

$XDG_CONFIG_HOME/chicken/setup.defaults
             User specific setup.defaults file. ( $XDG_CONFIG_HOME defaults to $HOME/.config )

       $prefix/share/chicken/setup.default
             System-wide setup.defaults file.

       $XDG_CACHE_HOME/chicken-install/
             Default directory for cached eggs. ( $XDG_CACHE_HOME defaults to $HOME/.cache )
