NAME

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

SYNOPSIS

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:

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

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