Indices and differentiation. CLN.

[Marko Riedel]

Greetings.

Two questions:

1. Could you make precompiled CLN library binaries for Linux (RPM
format) available somewhere on the web?

2. What is wrong here? I downloaded and installed
GiNaC-0.9.1-1.i386.rpm from
ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/rpm/ and I downloaded and
compiled cln-1.1.1.tar.gz.

riedel at linuxfast:qselav > cat test.cpp
#include <stdio.h>
#include <ginac/ginac.h>
using namespace std;
using namespace GiNaC;

static symbol g("g");
static symbol z("z");


int main(int argc, char **argv){
  ex T;

  T=indexed(g, idx(3, 1))*pow(z, 3);
  cout << T.diff(z) << endl;
}
