gsoap calc++ example ended up with error

I am trying to build calc++ after looking into tutorial given here https://www.genivia.com/examples/calc++/index.html but end up with error as shown below.

Here are the steps i followed

  1. wsdl2h -o calc.h http://www.genivia.com/calc.wsdl [This created the header file and i am not sure what to do file "typemap.dat" file so i proceed with second step]

  2. soapcpp2 -j -r -CL calc.h [This generates the required files and i downloaded the calcclient.cpp , copied the stdsoap2.h and stdsoap2.cpp in the same folder]

  3. g++ -o calcclient calcclient.cpp stdsoap2.cpp soapC.cpp soapcalcProxy.cpp [This step ends with the error shown below]

Can anybody help me regarding this, i am totally new to gsoap and trying to build something with it so i decided to start with gsoap example but getting this big error. I am doing this in Ubuntu and following the exact steps which is given in the tutorial.Please check error below

Perhaps you are passing one or more arguments as a pointer. The correct proxy call should look like this:

#include "soapcalcProxy.h"
#include "calc.nsmap"

  double a, b, result;
  calcProxy calc("http://server.com/path");
  a = 1.23;
  b = 4.56;
  int err = calc.add(a, b, result);
