Re: [Orca-robotics-users] Laser Consumer

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hello,

I didn't send the code because I copied and pasted the code from the LaserFeatureExtractor component. I also forgot to say that I am using Orca 2.10. 

The relevant code in my header file is:

    // Consumers
    orcaifaceimpl::StoringRangeScanner2dConsumerImplPtr laserConsumer_;

    // Context
    orcaice::Context context_;

I have the following fuction to create the comsumer:

void 
MainThread::connectToLaser()
{
    laserConsumer_->subscribeWithTag( "LaserScanner2d", this, subsysName() );
    context_.tracer().info( "Connected to laser." );
}

I could not find any call not 'new' then I added:

void 
MainThread::connectToLaser()
{
    laserConsumer_(new orcaifaceimpl::StoringRangeScanner2dConsumerImplPtr( context_ );
    laserConsumer_->subscribeWithTag( "LaserScanner2d", this, subsysName() );
    context_.tracer().info( "Connected to laser." );
}

After this I got a compilation error:

*original= error: no se encuentra una funcion coincidente para la llamada a*
*translation= error: no matching function for call to *

â€˜IceUtil::Handle<orcaifaceimpl::StoringConsumerImpl<
    IceInternal::ProxyHandle<IceProxy::orca::RangeScanner2d>,

    IceInternal::Handle<orca::RangeScanner2dData> 
> >::Handle(orcaice::Context&)â€™

/usr/include/IceUtil/Handle.h:163: note: *original= los candidatos son:* 
                                         *translation= candidates are:*

Asunto: RE: [Orca-robotics-users] Laser Consumer

Hi Jose,
Without seeing the code my guess is that the laser consumer is not created. In laserfeatureextractor the laserConsumer_ is defined as a smart pointer so one has to call 'new' to actually create it. This is done in the constructor of MainThread:
...
laserConsumer_(new orcaifaceimpl::StoringRangeScanner2dConsumerImpl(context)), 
...

Do you have this in your component?

Cheers,
Alex m.
