NAME

     chicken-install — download and install extension libraries for CHICKEN Scheme

SYNOPSIS

     chicken-install [OPTION ...] [NAME[:VERSION] ...]

DESCRIPTION

     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.

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

     -from-list filename
             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, -D name
             Register feature name, usable as a condition in cond-expand clauses.

ENVIRONMENT

     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).

FILES

     $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 )

EXIT STATUS

     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.

EXAMPLES

     Install ‘regex’ egg as root user:

           # chicken-install regex

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

           $ chicken-install -s regex

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

           $ SUDO=/usr/bin/doas chicken-install -s regex
