Orocos-users

Hi,

I wanted to use the rtt_dot_service to take a picture of my setup, but
it decided to die:

$ rosrun ocl deployer-gnulinux
0.218 [ Warning][DeploymentComponent::import] The ROS package 'ocl' in
'/home/mk/src/stacks/orocos_toolchain/ocl' nor its dependencies
contained a lib/orocos directory. I'll look in the RTT_COMPONENT_PATH
next.
Switched to : Deployer

This console reader allows you to browse and manipulate
TaskContexts.
You can type in an operation, expression, create or change
variables.
(type 'help' for instructions and 'ls' for context info)

TAB completion and HISTORY is available ('bash' like)

Use 'Ctrl-D' or type 'quit' to exit this program.

Fireing up gdb yields the following:

Thanks for the back-trace. It seems dot service is trying to add an operation
which has not been initialized. I have pushed a patch to master/2.5 to detect
this and refuse to add it with an error message.

top of git of the orocos_toolchain_ros or top of git of the rtt repos ? Please
post the rtt git hash to be sure...
