Hi all Since ginsh is built on top of CINT, it seemed reasonable to hope that GiNaC might able to be run from insite ROOT -- has anybody been able to do this? ROOT is here: http://root.cern.ch/ With the following simple test program,

#include <iostream> #include <ginac/ginac.h>

using namespace std; using namespace GiNaC;

int main(){ symbol x("x");

ex y = pow(x+1,3);

ex dydx = y.diff(x);

cerr << dydx; }

I get an error message from ROOT

Processing roottest.C... Limitation: Reference member not supported. Please use pointer FILE:/usr/include/ginac/print.h LINE:101

So maybe I can't use GiNaC inside ROOT? This is with GiNaC 1.3.2. Would appreciate any suggestions. How does gTybalt get around this? Cheers JP
