This project has moved. Mid December, 2008, the project moved to Google code: http://code.google.com/p/opkg/
Prior to that date, a mailing list for discussion was available here: http://lists.openmoko.org/mailman/listinfo/opkg-devel Source code was available in the subversion repository: http://svn.openmoko.org/trunk/src/target/opkg/. The repository could also be viewed online. |
opkg (Open PacKaGe Management) is a lightweight package management system based on Ipkg.

[edit] Usage
usage: opkg [options...] sub-command [arguments...]
opkg must have one sub-command argument where sub-command is one of:
[edit] Package Manipulation Commands
update Update list of available packages upgrade Upgrade installed packages (see also --download-only) install <pkgs> Install package(s) (see also --download-only) configure <pkgs> Configure unpacked package(s) remove <pkgs|regexp> Remove package(s) flag <flag> <pkgs> Flag package(s) <flag>=hold|noprune|user|ok|installed|unpacked (one per invocation)
[edit] Informational Commands
list List available packages list-installed List installed packages list-upgradable List installed and upgradable packages files <pkg> List files belonging to <pkg> search <file|regexp> List package providing <file> info [pkg|regexp] Display all info for <pkg> status [pkg|regexp] Display all status for <pkg> download <pkg> Download <pkg> to current directory compare-versions <v1> <op> <v2> compare versions using <= < > >= = << >> print-architecture List installable package architectures
whatdepends [-A] [pkgname|pat]+ whatdependsrec [-A] [pkgname|pat]+ whatprovides [-A] [pkgname|pat]+ whatconflicts [-A] [pkgname|pat]+ whatreplaces [-A] [pkgname|pat]+
[edit] RegEx for packages and filenames
regexp could be something like 'pkgname*' '*file*' or similar e.g. opkg info 'libstd*' or opkg search '*libop*' or opkg remove 'libncur*'
[edit] Options
-A Query all packages not just those installed --cache <directory> Use a package cache -d, --dest <dest_name> Use <dest_name> as the the root directory for package installation, removal, upgrading. <dest_name> should be a defined dest name from the configuration file, (but can also be a directory name in a pinch). -f, --conf <conf_file> Use <conf_file> as the opkg configuration file -o, --offline-root <dir> Use <dir> as the root directory for offline installation of packages. -V, --verbosity <level> Set verbosity level to <level>. Verbosity levels: 0 errors only 1 normal messages (default) 2 informative messages 3 debug 4 debug level 2
[edit] Force Options
--force-depends Install/remove despite failed dependencies --force-downgrade Allow opkg to downgrade packages --force-maintainer Overwrite preexisting config files --force-overwrite Overwrite files from other package(s) --force-reinstall Reinstall package(s) --force-removal-of-dependent-packages Remove package and all dependencies --force-space Disable free space checks
[edit] other options
--autoremove Remove packages that were installed automatically to satisfy dependencies --download-only No action -- download only --noaction No action -- test only --nodeps Do not follow dependencies -t, --tmp-dir Specify tmp-dir.
[edit] configuration files
In SHR the files are located in the directory /etc/opkg/ opkg.conf contains the main config options
arch.conf defines the priorities for different feeds/package trees/architectures
*-feed.conf contain the source type, a name and the path to the packages (comparable to debian)
[edit] Tricks
[edit] Reinstall all installed packages
At one point I ended up doing a complete upgrade before i had updated my opkg. As a result i borked a lot af packages. To reinstall them all, you can use this little sed magic.
opkg --force-reinstall install `opkg list_installed | sed 's/ - .*//'`
[edit] Upgrade after downloading all needed packages
To make sure that opkg upgrade does not break your system because of an unstable connection do:
opkg update opkg --cache cachedir --download-only upgrade opkg --cache cachedir upgrade
Add a line "option cache cachedir" to /etc/opkg/opkg.conf to avoid the --cache option on command line.
