Hi Daniel,
thank you very much for your help! This is what I found out:

package to have no dependencies, it compiles (on the gumstix using the
native compiler) and runs just fine. If I add the roscpp dependency to
the manifest.xml it compiles (on the gumstix using the native
compiler) just fine but gets stuck within the futex() call. Below I
attachted the list of linked libraries for both cases [1].
The main problem is that not only my package get stuck in the futex()
call but also e.g. the rosout binary. The rosout package also depends
on roscpp, so I guess the problem lies somewhere there or within the
dependencies it loads.

On my build system I have a rostoolchain.cmake wich points to the
cross-compilation stuff. I removed this file when I copied ros to the
embedded system.

think it finds all needed libraries. See [1].
Concerning compilation. By now I have tried out some different ways:
- Cross-compilation as described in the howtos I linked in my first
post. I compiled ROS and the hello_world package on my build machine
(ubuntu 10.04) with the open-embedded toolchain. Copied everything to
gumstix --> rosout and hello_world get stuck within futex().
- Complete native compilation of ROS: I did a svn checkout of ROS on
the gumstix and compiled everything there (which takes a while...).
Then I copied the hello world sources and compiled hello world there.
--> rosout and hello_world get stuck within futex().
At the moment I am running out of ideas what else I could try...
Thanks again
Sebastian
