[Rock-dev] using base::NamedVector<> as ports

[Ajish Babu]

Hi all,

I tried to use the base::NamedVector<..> as port types.

when I include directly in the orogen like *output_port("wrenches",
"***/base/NamedVector< base/samples/Wrench >*")*

/ mars_core.orogen:231: type /base/NamedVector< /base/samples/Wrench

is not declared (Orocos::Generation::ConfigError)

Typelib[WARN]:
/home/babu-dfki/HDSDA2/DFKI-ROCK/install/include/base/NamedVector.hpp:12: ignoring
the empty struct/class /base/NamedVector</base/samples/Wrench>
Typelib[WARN]:
/home/babu-dfki/HDSDA2/DFKI-ROCK/simulation/orogen/mars_core/.orogen/typekit/types/simulation/ForceTorqueSensorTypes.hpp:8:
cannot create the /simulation/Wrenches typedef, as it points to
/base/NamedVector</base/samples/Wrench> which is ignored/

and when I do *typedef base::NamedVector< base::samples::Wrench >
Wrenches;* and then try to use it

/mars_core.orogen:230: type /simulation/Wrenches is not declared
(Orocos::Generation::ConfigError)//
// Typelib[WARN]:
/home/babu-dfki/HDSDA2/DFKI-ROCK/install/include/base/NamedVector.hpp:12: ignoring
the empty struct/class /base/NamedVector</base/samples/Wrench>//
// Typelib[WARN]:
/home/babu-dfki/HDSDA2/DFKI-ROCK/simulation/orogen/mars_core/.orogen/typekit/types/simulation/ForceTorqueSensorTypes.hpp:8:
cannot create the /simulation/Wrenches typedef, as it points to
/base/NamedVector</base/samples/Wrench> which is ignored/

It seems to work only if I create a new type like

///struct////Wrenches////:////public////base//:://NamedVector//<//Wrench//>/
///{/
///};/

Does anybody know what is going on or how it can be done without a new type?

This is due to a limitation in gccxml (which clang will hopefully not
have ...). See

Hm,
I don't see how clang will solve this issue. I know, that the
typedef will work, and that with clang we can catch template
declarations in general. But typelib does not support
templates. Only specialized instantiations.

Since typelib knows that the type is being used, it can emit it into a
header (as e.g. a typedef) so that clang emits the type.

This actually could have been done with gccxml already ...
