Hi all,

As mentioned some days ago, I need some help on c++.
I want to create a new class ClumpTemplate. When it is constructed it  
just should store some informations:
- an id for the template
- number of clump members (numCM)
- relative radii list (length == numCM)
- relative postions list (length == numCM)

For initiation the length (numCM) is unknown. This is what I have done  
until know:

//######code for ClumpTemplate.hpp:

#pragma once

class ClumpTemplate {
	public:
		typedef const int id_ct;
		typedef const shared_ptr<ClumpTemplate> ct;
		ClumpTemplate ct;

		int numCM;		//number of clump members
		Real[] rad;		//relative radii list
		Vector3r[] pos;		//rel. position vector list

		int ClumpTemplate();	//returns id
};


//######code for ClumpTemplate.cpp:

#include <yade/core/ClumpTemplate.hpp>
class ClumpTemplate;

// set id to -1, if not constructed yet
const ClumpTemplate::id_ct ClumpTemplate::ID_NONE=ClumpTemplate::id_ct(-1);

int ClumpTemplate::ClumpTemplate(){
	int id = this.id_ct + 1;
	return id;
}

//####compiler says:
