opkg: Package Manager

TODO

Configuration

A configuration is performed via a set of files /etc/opkg/*.conf. Typical configuration may look like this:

src base http://packages.litebsd.org/mipsel/base
option cache_dir "/var/cache/opkg"
option lists_dir "/var/lib/opkg/lists"
option info_dir "/var/lib/opkg/info"
option status_file "/var/lib/opkg/status"
option lock_file "/var/run/opkg.lock"
option tmp_dir "/tmp"

The following statements are available:

  • option name value -- Set value for an option
  • src name url -- Add a source of packages
  • src/gz name url -- Add a source with gzipped data
  • dist name url -- Add a source with Debian structure
  • dist/gz name url -- Add a source with Debian structure, gzipped
  • dest name path -- Register destination with given path
  • arch name priority -- Register architecture with given priority

Installation Destinations

The format of destination lines is simply the keyword dest, followed by a name for this destination (this can be anything), followed by a filesystem location. Any destination that has been thus configured can then be specified on the opkg command line like this:

opkg install somepackage -d destination_name

By default, the only destination is "root", with path "/".

Adjust Architectures

By default, opkg only allows packages with the architecture all (= architecture independent) and the architecture of the installed target (mipsel for example). In order to source packages from a foreign, but compatible target, the list of allowed architectures can be overrided in opkg.conf with the use of arch options. For example:

arch all 100
arch mips32r2el 200
arch mips64r2el 300

The number specifies a priority index which is used by opkg to determine which package to prefer in case it is available in multiple architectures.
