Marshalling vector<double>

Hi all,
I'm sorry for this stupid question but is all the morning that I'm
trying to solve this problem and I didn't find ocl 2.x examples.

I'm preparing a PID controller and I want to load the parameters from a
cpf file using PropertyMarshaller.

This is the code (piece of):

#include <rtt/marsh/PropertyDemarshaller.hpp>
#include <rtt/marsh/PropertyMarshaller.hpp>
#include <rtt/marsh/MarshallInterface.hpp>
#include <rtt/Property.hpp>
#include <Eigen/Core>
#include <rtt/RTT.hpp>
#include <iostream>

using namespace KDL;
using namespace Eigen;
using namespace RTT;
using namespace std;

class PdController
: public RTT::TaskContext
{

protected:
...
Property< std::vector<double> > pParameters;
Property< std::vector<double> > iParameters;
Property< std::vector<double> > dParameters;

public:
PdController(string const& name)
: TaskContext(name),
...
pParameters("pParameters","proportional parameters of the axes
",vector<double>(6,0)),
iParameters("iParameters","integrative parameters of the axes
",vector<double>(6,0)),
dParameters("dParameters","derivative parameters of the axes
",vector<double>(6,0))

{

this->properties()->addProperty( pParameters);
this->properties()->addProperty( iParameters);
this->properties()->addProperty( dParameters);
}

bool configureHook()
{

boost::shared_ptr<Marshalling> Marshalling =
this->getProvider<RTT::Marshalling>("marshalling");
result = Marshalling->writeProperties("pidParameters.cpf");

...
}

compiling:
/root/workspace/stem/pdController/src/pdController-component.hpp:81:
error: ‘Marshalling’ was not declared in this scope
/root/workspace/stem/pdController/src/pdController-component.hpp:81:
error: template argument 1 is invalid
/root/workspace/stem/pdController/src/pdController-component.hpp:81:
error: invalid type in declaration before ‘=’ token
/root/workspace/stem/pdController/src/pdController-component.hpp:81:
error: ‘Marshalling’ is not a member of ‘RTT’
/root/workspace/stem/pdController/src/pdController-component.hpp:81:
error: ‘Marshalling’ is not a member of ‘RTT’
/root/workspace/stem/pdController/src/pdController-component.hpp:81:
error: no matching function for call to ‘PdController::getProvider(const
char [12])’

What's wrong?

Can I propose a wiki page with the links of all ocl examples available
on internet?

Thanks a lot!
Fabrizio

You don't need these. You should instead include:
#include <rtt/marsh/Marshaller.hpp>

You forgot to include the Marshalling.hpp header.

Of course :-) Make a child page here:

When our components are ready I'll post there ;)
