Hi,

I got an error.  The library/plugin requires me to define this function in this way, and I am trying to assess yade's pointers within the function:

static void NAG_CALL objfun(Integer n, double x[], double *objf, double objgrd[], Nag_Comm *comm){
    shared_ptr<Scene> scene = Omega()::instance().getScene();
}

Error:
pkg/dem/DataClass/InteractionGeometry/IgFunc.cpp: In function 'void objfun(Integer, double*, double*, double*, Nag_Comm*)':
pkg/dem/DataClass/InteractionGeometry/IgFunc.cpp:420: error: conversion from 'Omega' to non-scalar type 'boost::shared_ptr<Scene>' requested
pkg/dem/DataClass/InteractionGeometry/IgFunc.cpp:420: error: expected ',' or ';' before '::' token


After that is done, I'm planning to do this:
    //shared_ptr<BodyContainer>& bodies = scene->bodies;
    //Body* b1 = ( *bodies ) [id1].get();
    //Body* b2 = ( *bodies ) [id2].get();



Yours,

Boon
