Hi,
I have converted the example of simple tcp client to rtt2.x using the scripts
provided by Peter. The conversion worked more or less smoothly and only a few
changes were needed : new cmake and a change with the name of a function.
I have tried to run the example, but I got this error and I'm a bit lost:
0.059 [ ERROR ][DeploymentComponent::loadComponent] Unable to create Orocos
Component 'SimpleNonPeriodicClient': unknown component type.
0.059 [ Warning][DeploymentComponent::loadComponents] Could not
configure 'SimpleNonPeriodicClient': No such peer.
0.059 [ ERROR ][Logger] Failed to load a component: aborting kick-start.
any light to help me in the path .....
Regards,
Leo
PS. I would like to send the example with the new cmake to Stephen Roderick to
update the wiki page, but when it works ...

Did you compile with '-DRTT_COMPONENT' defined + the ORO_CREATE_COMPONENT
macro ?
Did you import the directory where the .so library exists ?

I used the example of CMake in the documentation. Have I to add this?
yes,
ORO_CREATE_COMPONENT(SimpleNonPeriodicClient)

nops ....
import(SimpleNonPeriodicClient-gnulinux)?

Please do! Which actually brings up a larger topic ...
I suggest creation of an "examples" repository on Gitorious, that contains tested and working examples of how to do things in Orocos. This goes from Peter's RTT tutorial, through the several examples I have on the Orocos wiki, to KDL and BFL examples, to a user-perspective hello world component example, and other examples leading up to a full and complete example working robot system. As an ecosystem, we remain utterly lacking in this regard. It is the very first critique I consistenly get from new users ...
I am happy to maintain such a repo.

Ok,
I have loaded the component. However, the problem (I think) is somthing
reported before. The component uses a port that send a std:string. You must
specify to RTT to add this kind of type adding:
RTT::types::TypeInfoRepository::Instance()->addType( new
RTT::types::StdVectorTemplateTypeInfo<std::string,true>("strings") );
but I got this error:
SimpleNonPeriodicClient.cpp: In
constructor ‘SimpleNonPeriodicClient::SimpleNonPeriodicClient(std::string)’:
/home/users/leopold.palomo/robotica/projects/mrcuoxar/soft/example/SimpleNonPeriodicClient/SimpleNonPeriodicClient.cpp:107:
error: invalid use of incomplete type ‘struct
RTT::types::StdVectorTemplateTypeInfo<std::basic_string

[CMakeFiles/SimpleNonPeriodicClient.dir/SimpleNonPeriodicClient.cpp.o] Error
1
make[1]: *** [CMakeFiles/SimpleNonPeriodicClient.dir/all] Error 2
make: *** [all] Error 2
Any idea?

yes, yes, but I would like to send something that works.

Do you really need this ? If your port uses 'string', but it's not
known in the deployer,
it must be because the RTT_COMPONENT_PATH is wrong.
The 'strings' type (which I doubt!) can be added by writing:
RTT::types::Types()->addType( new
SequenceTypeInfo<std::string,true>("strings"));
Setting the type path automatically will be part of the next release,
which will liberate
you from the hurdles you had now with RTT_COMPONENT_PATH.
