Om 2007.2
Om 2008.8 is the successor of Om 2007.2


(Other distributions)


Om 2007.2 is one of the many distributions that currently work on the Openmoko phones. You can compare a distribution with an Operating System on normal computers. It gives the phone all the software needed for operating. For more information about the different flavors, see distributions.

Om 2007.2 is the second version of the Openmoko distribution. Development began on 2007-07-26.

Goals of this version are an improved set of PIM applications, improved theming that fixes a lot of the usability problems of the first generation design, more formalized UI guidelines and a number of changes in the build system. The latter should introduce more recent software by staying closer in sync with upstream org.openembedded.dev.

An official announcement was made by Sean Moss-Pultz on August 20:

(Initially this was named OM-2008 in SVN but renamed shortly after that.)

Building 2007.2

Why to build

Before getting your feet wet, step back a moment and ask yourself why you want to build the Openmoko distribution image. Chances are you are a kernel and application developer and just want to develop on your package -- in that case building Openmoko is completely unnecessary and a waste of time. You may rather want to use the Openmoko Toolchain and build only the stuff that is interesting to you.

How to build

The MokoMakefile is now able to build Om 2007.2 images. If you use this new version of the MokoMakefile, you can ignore everything below and just continue building Om 2007.2 in the same way that you previously built images (i.e. according to MokoMakefile). Make sure you set the generation correctly at the top of the file.

Follow the getting started steps of OpenEmbedded. It is suggested to use Bitbake 1.8.8 at least.

NOTE: Instead of using git.openmoko.org (as indicated in OE GettingStarted), please make sure to use git.openmoko.org as monotone server. This ensures you have a working revision of the metadata and will render a successful build


Put the following in your local.conf

BBFILES = "${HOME}/oe/org.openembedded.dev/packages/*/*.bb"

MACHINE = "om-gta01"
DISTRO = "openmoko"

ENABLE_BINARY_LOCALE_GENERATION = "1"
GLIBC_GENERATE_LOCALES = "en_GB.UTF-8"

For multi-core machines, the following additions can be used for a speed-up (numbers should be tweaked based on the actual number of cores):

PARALLEL_MAKE = "-j 4"
BB_NUMBER_THREADS = "4"

To free disk space after builds, add:

INHERIT += "rm_work"

Replace "${HOME}/oe" with the path to where your "org.openembeded.dev" folder lives. For the other entries have a look at conf/local.conf.sample about their meaning.

Run bitbake <package name> (e.g. openmoko-devel-image).

How to enable autorev

First apply the following patch to bitbake.

http://lists.linuxtogo.org/pipermail/openembedded-devel/2007-September/003035.html

Add the following line to your local.conf

 require conf/distro/include/moko-autorev.inc

Then run bitbake as normal. Openmoko will now build with latest SVN checkouts.

Build issues

Wrong certificate

You may get something like this while the bitbake recipes are parsed:

Error validating server certificate for 'https://libw100.svn.sf.net:443':
 - The certificate hostname does not match.
 Certificate information:
  - Hostname: *.svn.sourceforge.net
  - Valid: from Fri, 27 Oct 2006 12:05:58 GMT until Sun, 28 Oct 2007 13:05:58 GMT
  - Issuer: Equifax Secure Certificate Authority, Equifax, US
  - Fingerprint: f2:6c:fe:bb:82:92:30:09:72:dd:1c:b3:e7:56:69:c7:7a:df:67:3e

That is an issue in a bitbake file. One should not use the short-name for sourceforge (sf.net) when certificates are only for exact host names. Accept the certificate and everything is fine for now.

openmoko-libs FTBFS

Some applications have not been fully modified to build with the new libraries of Openmoko and still need the old-style openmoko-libs package. libmokogsm which is needed for openmoko-libs then fails to build. As a workaround you can remove the not yet ported applications that need openmoko-libs making it unneccessary itself. To do this edit packages/tasks/openmoko-taks.bb and find the following lines:

.
.
.
 openmoko-terminal \
 matchbox-panel-2 \
 matchbox-panel-2-applets \
 matchbox-applet-inputmanager \
#  openmoko-appmanager \
 matchbox-keyboard \
 matchbox-stroke \
 openmoko-keyboard \
.
.
.

Now put a hash (#) before openmoko-terminal and openmoko-keyboard. You can verify that openmoko-libs is not needed any more by issuing bitbake -g openmoko-devel-image (= creates a dependency graph). There should be no mentioning of openmoko-libs in the file task-depends.dot. Please note that the graphicall terminal and the virtual keyboard will be missing now. You can still have terminal access by following the USB Networking guide. For keyboard input in Qemu add the -usbdevice keyboard switch.


gtk+ fails building w/ gtkcombobox.c

If you get these errors:

Go to your /build/tmp/work/fic-gta01-angstrom-linux-gnueabi/gtk+-2.10.14-r3/gtk+-2.10.14/gtk directory, and patch gtkcombobox.c with the following:

Building glibc fails with a segfault in QEMU

If your build aborts and you see something like this:

NOTE: package glibc-2.5: started
NOTE: package glibc-2.5-r6: task do_package: started
NOTE: preparing tree for binary locale generation
NOTE: generating locale en_US (UTF-8)

NOTE: Tasks Summary: Attempted 271 tasks of which 0 didn't need to be rerun and 1 failed.
ERROR: '/home/moko/oe/org.openembedded.dev/packages/glibc/glibc_2.5.bb' failed

Try editing your local.conf file. Change:

ENABLE_BINARY_LOCALE_GENERATION = "1"

to

ENABLE_BINARY_LOCALE_GENERATION = "0"

and restart the build. This may have some effect on internationalization (you will see a warning indicating that), but at least the build will continue. Thanks to rwhitby for the tip.

Alternatively, as suggested by XorA in #openmoko, if you are running a 64-bit host distribution, try forcing a different QEMU rev, also in local.conf:

PREFERRED_VERSION_qemu-native = "0.9.0+cvs20070701"
SRCDATE_qemu-native = 20070701


libxml2-native fails with xmlCatalogPtr errors

Pre-built images

Buildhost directory structure

The content of the Openmoko build server directory is available at

It contains

  • cache
    • Internal caching data, not for human interpretation
  • cross
    • The cross-compilation toolchain used. You can download this and use it on your local machine.
  • deploy
    • deploy/images
      • The filesystem, kernel and bootloader images to be flashed into NAND
    • deploy/ipk
      • the .ipk packages
  • rootfs
    • the extracted root filesystem. Please use the images from deploy/images instead
  • staging
    • no user servicable parts inside
  • stamp
    • internal state data
  • work
    • the actual build trees (including patches source code and binaries) of the individual packages

Updating your image

Now that you have a functional 2007.2 image on your Neo, you will want to keep it updated. Fortunately, ipkg is already set up to pull updated packages from the openmoko buildhost.

On the phone, in the terminal (or via ssh), if you have a live internet connection and DNS resolution set up in /etc/resolv.conf:

ipkg update && ipkg upgrade

will bring your installed packages up to the most recent versions. Also have a look at alternative/additional ipkg sources at repositories.

If you are also building your own images and packages, you can also run a simple httpd on your build host and serve your own ipkg files to the Neo.

On the build host, for example:

thttpd -d <path_to_moko/tmp/deploy/glibc/ipk> -p 8080

will serve your packages on port 8080.

Then, on the neo, make a new file at /etc/ipkg/local-feed.conf with these contents:

src/gz local-all http://192.168.0.200:8080/all
src/gz local-armv4t http://192.168.0.200:8080/armv4t
src/gz local-om-gta01 http://192.168.0.200:8080/om-gta01

and ipkg on the Neo (update-upgrade) will pick up files from your local build host's repository (assuming its IP address is 192.168.0.200, as is default in the USB Networking setup) in addition to the openmoko buildhost.

Or better yet, change the 192.168.0.200:8080 addresses above to the eth0 IP address of your build machine (instead of the usb0 IP address), and then you can access your local repository with your Neo plugged into any machine on your local net, or even via bluetooth.

Also if you are building your own packages or packages from the OE database that aren't part of Openmoko by default, you can install those packages as follows.

On the build host:

bitbake <name_of_package>
bitbake -crebuild package-index

Then on the Neo:

ipkg update
ipkg install <name_of_package>

The new package might not show up in the program menu until you reboot or restart X.
