I am trying to install SymbolicC++ from SymbolicC++3-3.35-ac.tar on Ubuntu 15.10. I did a ./configure, make, sudo make install with no errors.

I tried to compile the following with g++ test1.cpp -lsymbolicc++:

#include <iostream>
#include "symbolicc++.h" 
using namespace std;

int main(void)
{
  Symbolic x("x");
  cout << integrate(x+1, x) <<endl;       // => 1/2*x^(2)+x
  Symbolic y("y");
  cout << df(y, x) << endl;               // => 0
  cout << df(y[x], x) << endl;            // => df(y[x],x)
  cout << df(exp(cos(y[x])), x) << endl ; 
                             // => -sin(y[x])*df(y[x],x)*e^cos(y[x])
  return 0;
}

This code was from the Wikipedia article on SymbolicC++

I get the following errors:
