Typegen error

Submitted by luca.gherardi on Fri, 2011-10-28 08:43

Hi all.

I'm working with the latest debian packages of the Orocos-toolchain in ROS (v2.5 - electric - Ubuntu 11.04).

When I try to use typegen it reports me the following errors:

luca@luca-desktop:~/workspace/YouBot-types$ typegen --transport=corba --output . YouBot-types /home/brics/workspace/YouBot/YouBot-types.hpp 
/opt/ros/electric/stacks/orocos_toolchain/orogen/lib/orogen/gen/imports.rb:19:in `merge_xml': cannot load xml: plugin not found (ArgumentError)
    from /opt/ros/electric/stacks/orocos_toolchain/orogen/lib/orogen/gen/imports.rb:19:in `from_raw_data'
    from /opt/ros/electric/stacks/orocos_toolchain/orogen/lib/orogen/gen/project.rb:259:in `using_rtt_typekit'
    from /opt/ros/electric/stacks/orocos_toolchain/orogen/lib/orogen/gen/typekit.rb:823:in `initialize'
    from /opt/ros/electric/stacks/orocos_toolchain/orogen/bin/typegen:11:in `new'
    from /opt/ros/electric/stacks/orocos_toolchain/orogen/bin/typegen:11

Is it a bug?

The same input file worked with the toolchain v2.4.

Thanks, Luca

Thank you!
 
Anyway I downloaded the source from gitorius 3 days ago and they works.
