Hello,

When I start up the deployer, I get a warning : [ Warning][DeploymentComponent::loadLibrary] Component type name ... already used: overriding. in my logging. Although the load of the dynamic library is only done once in the .cpf file. What can be the reason for this warning ?

Problem loading a component library : Component type name alread

Submitted by willy on Fri, 2012-01-06 23:08.

Hi all,

I have a little problem when loading a multi component library of my own.
it says :
23.898 [ Warning][DeploymentComponent::import] Component type name
arp_hml::CanOpenController already used: overriding.
Whereas a "displayComponentTypes" command before this doesn't show it.

Is there anything wrong in my code ? I am quite sure I only have one
ORO_CREATE_COMPONENT( arp_hml::CanOpenController)

I don't know how to investigate this.
I am using
root@beta(8.2):~# rosrun ocl deployer-gnulinux --version
OROCOS Toolchain version '2.5.0' ( GCC 4.4.5 ) -- GNU/Linux.

Here is the complete log in the TaskBrowser:

Deployer [S]> import("arp_hml")
23.898 [ Warning][DeploymentComponent::import] Component type name
arp_hml::CanOpenController already used: overriding.
= true

Deployer [S]> displayComponentTypes
I can create the following component types:
OCL::ConsoleReporting
OCL::FileReporting
OCL::HMIConsoleOutput
OCL::HelloWorld
OCL::LuaComponent
OCL::LuaTLSFComponent
OCL::TcpReporting
OCL::TimerComponent

Well, the error is at least consistent. You first defined an
arp_hml::CanOpenController in libarp_hml-io-gnulinux.so and next one
in libarp_hml-can-gnulinux.so.

I guess one links with the other and as such, the component type is seen
twice by the import.

Since you're using multi-component libraries, you're not using
ORO_CREATE_COMPONENT but ORO_LIST_COMPONENT_TYPE.

The only thing we could test for during the import is to see if the address
of the factory function is the same, and then suppress the warning.

Oh, I am working too late, I didn't see this on my own :( sorry

Right ! There is a link:
target_link_libraries(arp_hml-io arp_hml-can)

In fact arp_hml-can has only one component with ORO_CREATE_COMPONENT , and
arp_hml-io has 2 component with the ORO_CREATE_COMPONENT_LIBRARY +
2*ORO_LIST_COMPONENT_TYPE

Should I do something on my own to suppress my link ? or is it just a "too"
verbose warning in my case ?

Thanks for support.

.. don't mix these two kinds of macros. We might have worked around it in
the deployer such that it works anyway, but you have been warned, it's
untested.

You can't fix this outside the deployer, except fixing your macro issue.

hum, in fact I never read that before, because I get those macros from
"tutorials", so I have always lived with it. I can then use
ORO_CREATE_COMPONENT_
LIBRARY + ORO_LIST_COMPONENT_TYPE every where ? even for a single component
property, so I don't have my issue ?
