Ok, got the problem -- solved --
It's related to this:
http://www.kieltech.de/uweswiki/Xenomai -> Testing Xenomai
you have to build the xenomai packages with " --enable-dlopen-skins"
If you have done (and reinstalled) this, you have to add yourself to the
xenomai group if you have followed this xenomai instructions
http://www.stanley.gatech.edu/skelly/uncategorized/installing-xenomai-on-ubuntu-12-04/.
Afterward for me everything seems to work fine,
Best,
Matthias
P.S. error to search for:
rb(main):001:0> require 'rorocos_ext'
LoadError: libnative.so.3: shared object cannot be dlopen()ed -

Recreating and resourcing the env.sh didn't help. Irb outputs some additional

If the suggestion from below (and rebuilding) does not help
try:
source env.sh
irb
> require 'orocos'
and post (if hopefully) the additional error msg.

Hello,
I think to remember, that I solved this error once by recreate the
env.sh with
autoproj envsh
and resource the environment
. env.sh
Maybe that helps.

Hi,
Thanks for your reply.
So I did:
rm -r tools/orocos.rb/
autoproj update
amake
but the error is still there. Maybe it was fixed in next or master?

Hi,
Please try to delete the whole orocos.rb folder and then run a update &&
build again.
We had some problems in the past with rebuilding of ruby packages.
Best,
Matthias

Hello,
I have created a component and wrote a script to run it by using the ruby
interface but running the script fails with an error:
Cannot require orocos.rb's Ruby/C extension
If you are using Rock, this should have been done automatically.
Run
amake orocos.rb
and try again
rebuilding orocos.rb doesn't help and I get the same error again. I'm running
the stable branch and target is Xenomai.
Thanks,
Siavash
