Common package options

The following outlines common configuration options available for packages.

LIBFOO_INSTALL_TYPE

Defines the installation type of this package. A package may be designed to be built and installed for just the target area, the stage area, both or maybe in the host directory. The following options are available for the installation type:

Type

Description

host

The host directory.

images

The images directory.

staging

The staging area.

staging_and_target

Both the staging an target area.

target

The target area.

The default installation type is target.

LIBFOO_INSTALL_TYPE = 'target'

See also LIBFOO_HOST_PROVIDES.

LIBFOO_LICENSE

A string or list of strings outlining the license information for a package. Outlining the license of a package is recommended. It is recommended to use SPDX registered licenses.

LIBFOO_LICENSE = ['GPL-2.0-only', 'MIT']

or

LIBFOO_LICENSE = 'GPL-2.0-or-later WITH Bison-exception-2.2'

or

LIBFOO_LICENSE = 'LicenseRef-MyCompanyLicense'

See also LIBFOO_LICENSE_FILES.

LIBFOO_LICENSE_FILES

A string or list of strings identifying the license files found inside the package sources which typically would match up to the defined LICENSE entries (respectively).

LIBFOO_LICENSE_FILES = [
    'LICENSE.GPLv2',
    'LICENSE.MIT',
]

or

LIBFOO_LICENSE_FILES = 'LICENSE'

See also LIBFOO_LICENSE.

LIBFOO_NEEDS

Note

The option replaces the legacy LIBFOO_DEPENDENCIES option.

Added in version 1.3.

List of package dependencies a given project has. If a project depends on another package, the package name should be listed in this option. This ensures releng-tool will process packages in the proper order. The following shows an example package libfoo being dependent on liba and libb being processed first:

LIBFOO_NEEDS = [
    'liba',
    'libb',
]

LIBFOO_SITE

The site where package sources/assets can be found. The site can be a URL of an archive, or describe a source control URL such as Git or SVN. The following outline a series of supported site definitions:

Changed in version 0.10: Support added for rsync+.

Changed in version 0.17: Support added for perforce+.

Changed in version 1.4: Support added for brz+.

Type

Prefix/Postfix

Breezy

brz+

Bazaar

bzr+

CVS

cvs+

Git

git+ or .git

Mercurial

hg+

Perforce

perforce+

rsync

URL

(wildcard)

Examples include:

LIBFOO_SITE = 'https://example.com/libfoo.git'
LIBFOO_SITE = 'cvs+:pserver:anonymous@cvs.example.com:/var/lib/cvsroot mymodule'
LIBFOO_SITE = 'svn+https://svn.example.com/repos/libfoo/c/branches/libfoo-1.2'
LIBFOO_SITE = 'https://www.example.com/files/libfoo.tar.gz'
LIBFOO_SITE = {
    DEFAULT_SITE: 'https://pkgs.example.com/releases/libfoo-${LIBFOO_VERSION}.tar.gz',
    '<mode>': 'https://git.example.com/libfoo.git',
}

A developer can also use LIBFOO_VCS_TYPE to explicitly define the version control system type without the need for a prefix hint. The use of a dictionary value is only useful when operating in development mode. For more information on each type’s formatting, see site definitions.

Using a specific type will create a dependency for a project that the respective host tool is installed on the host system. For example, if a Git site is set, the host system will need to have git installed on the system.

If no site is defined for a package, it will be considered a virtual package (i.e. has no content). If applicable, loaded extensions may provide support for custom site protocols.

Specifying a local site value with local will automatically configure a VCS-type of local.

See also LIBFOO_VCS_TYPE.

LIBFOO_TYPE

Changed in version 0.13: Support added for make.

Changed in version 0.16: Support added for meson.

Changed in version 1.3: Support added for cargo.

The package type. The default package type is a (Python) script-based package. releng-tool also provides a series of helper package types for common frameworks. The following outline a series of supported type definitions:

Type

Value

Autotools

autotools

Cargo

cargo

CMake

cmake

Make

make

Meson

meson

Python

python

SCons

scons

Script

script

For example:

LIBFOO_TYPE = 'script'

If no type is defined for a package, it will be considered a script-based package. If applicable, loaded extensions may provide support for custom types.

Using a specific type will create a dependency for a project that the respective host tool is installed on the host system. For example, if a CMake type is set, the host system will need to have cmake installed on the system.

LIBFOO_VERSION

The version of the package. Typically the version value should be formatted in a semantic versioning style, but it is up to the developer to decide the best version value to use for a package. It is important to note that the version value is used to determine build output folder names, cache files and more.

LIBFOO_VERSION = '1.0.0'

For some VCS types, the version value will be used to acquire a specific revision of sources. If for some case the desired version value cannot be gracefully defined (e.g. a version value libfoo-v1.0 will produce output directories such as libfoo-libfoo-v1.0), LIBFOO_REVISION can be used.
