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.

<pre wrap="">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

<pre wrap="">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
