@Ruby binding guy's:
I think the problem with orocos.rb is related to some linking
problems of the orocos extenstion.
I attached the ldd output and the CMakeCache from my installation. So
Far i see it should work.
I compared the CMakeCache with my local one and can't find the fault
here.
Has someone i idea what's going on here?
The ruby extension is not linked against ruby. In general it is not
nice but should not be a problem because the symbols are already known
if the extension is loaded by ruby.
You can try the following and post the output for all steps:
orocos.rb: rake
ruby —version
which ruby
which irb
irb -r 'orocos/rorocos'

rake: <done>

If you are using Rock, this should have been done automatically.
Run
amake orocos.rb
and try again
NotImplementedError: method `backtrace' called on unexpected T_NODE

Nice try but it is not such simple ;)
Best,
Matthias
