First of all you need a working haiku os build enviroment. There are several tutorials and documentations out for different Operatingsystems

over here

So after you have set up a nice enviroment to build haiku os you can check out the projectconceptor sources. Open a terminal and change directory into

    haiku/3rdparty

Therefore we create a BMessage wich will be our Node:

nodeMessage    = new BMessage(P_C_CLASS_TYPE);

P_C_CLASS_TYPE defines that this BMessage represent a node in the ProjectConceptor. Later there will also other kind of nodes like P_C_GROUP_TYPE
