[Gumstix-users] bitbake omap3-console-image generates ERROR: Unbuildable tasks were found

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi,

I'm new to gumstix and want to setup my build environment on my ubuntu
10.4 system. I followed the instructions on
http://www.gumstix.net/easyfaq/view/Overo-Setup-and-Programming/Setting-up-a-build-environment/114.html.

But when running the command:

$ bitbake omap3-console-image

I run into a problem; bitbake generates an error: "ERROR: Unbuildable
tasks were found.". Bitbake then tries to "Identifying dependency loops
(this may take a short while)..." but soon crashes with some python
Traceback output (the output is at the bottom of this message)

Anybody got any ideas how to solve this issue? I searched the internet
and the archives but I didn't spot anything relevant.

Thanks in advance,
Onno

The complete output is:

These are usually caused by circular dependencies and any circular
dependency chains found will be printed below. Increase the debug level
to see a list of unbuildable tasks.
