Version 2.0 of the opendreambox distribution is now available for download. It’s based on the “denzil” release of OpenEmbedded. You can get the Documentation in PDF and plaintext formats or browse the Git repository online.

Quick start:

git clone -b denzil git://
cd opendreambox
make help
make update
make image MACHINE=dm7020hd

New branch opendreambox-1.6

A new branch has been created in our opendreambox repository, as an effort to update both kernel and userspace tools to more recent versions.

You can build this branch using the new Makefile-opendreambox-1.6.

Instead of changing variables inside the Makefile, you can now optionally store your configuration in a file called build.conf. This should make it easier to update to future versions of the Makefile. You can, of course, still override variables from the command line, e.g. make -f Makefile-opendreambox-1.6 MACHINE=dm500hd.

A new option was added to use a single Git repository for all machines. Set SINGLE_REPOSITORY=1 to enable it. Using this option decreases traffic and storage requirements and might also be helpful for developers, who create changesets for more than one machine.

Developers, who are switching to 1.6 from an older Makefile-opendreambox should delete the bb directory, because a customized version of BitBake will be used from now on. Also, the new 1.6 branch will have to be checked out manually in this case.

The other Makefiles, which have been available before, were updated, too:


The two branches opendreambox and opendreambox-1.6 are currently equal to each other, but they will diverge once further work from OpenEmbedded will be merged into opendreambox. The current state has been tested mainly on DM500HD, DM800 and DM8000. DM7025 will be next. The powerpc port is completely untested for now. Reports are welcome, of course.

A note for users of Ubuntu 9.10

Ubuntu’s version of tar (1.22-1) includes a regression, which causes the build to fail with the following or a similar error:

NOTE: package libtool-cross-1.5.10-r4: task do_unpack: started
gzip: stdout: Broken pipe
tar: Child returned status 1
tar: Exiting with failure status due to previous errors

This problem has already been corrected in versions 1.22-1.1 and later, which however are currently not part of Ubuntu 9.10.

You can find installable builds of newer versions for various architectures on Launchpad.

opendreambox-1.5 moved to our server

Ladies and Gentlemen,

we decided to use our own Git repository as the main repository for opendreambox-1.5 from now on. This requires developers to update their Makefiles. While at it, we also created a local bitbake repository and backported support for fetching URLs from Git from a recent version to our ancient bitbake 1.4.2.

It is not recommended to use this Makefile with existing installations. Please start a new build environment instead. Otherwise you’d have to manually change to the new repository and delete the “bb” directory.

So, have a lot of fun using the new
Makefile-opendreambox-1.5! Please report any difficulties showing up with this new version.

[Update 2009/11/20]
Because of recurring problems with the git2svn gateway we used for enigma2, and because our version of bitbake is now able to handle Git repositories, we decided to disable the SVN repository completely. If you came here, because this caused your build to break, you should update your Makefile-opendreambox-1.5 now.

Developers, who already updated their Makefiles after the move of opendreambox-1.5, are also encouraged to update again. Today’s Makefile automatically updates bitbake whenever a new version becomes available.

A new home

Today, and moved to a new machine. All services should be up again by now, except for cvs and rsync, which have been serving only very old versions of openembedded and enigma2 for quite some time.

If you feel that something changed badly, please don’t hesitate to leave a comment.

Makefiles for OE (both 1.5 and HEAD)

If you’d like to create images from Git, you can try one of the new Makefiles.

Makefile-opendreambox-1.5 is the successor of the old monotone based Makefile-opendreambox.

Makefile-opendreambox builds from a much newer branch, of which opendreambox 1.6 will become a spin-off once a stable state is reached. Today it won’t even finish an image, but you’re invited to test it early and to report any problems occuring in your build environment, so we can fix them for you.

One notable thing is that the directory layout changed to create one subdirectory per platform and a shared directory for bitbake and the sources. If you’d like to keep the old directory structure for version 1.5, to upgrade without rebuilding everything, then you can set UPGRADE_FROM_MONOTONE=1 in the Makefile. But don’t forget to move away your monotone repository.

If you’re going to make commits to your new Git-repository, then you should definitely edit GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL, because this information will be kept in the commit history forever. Otherwise Git will create a mail adress from your local username and hostname.

The command to build an image has been unchanged: make -f Makefile-opendreambox-1.5 image
