problem in OPT++(C++ optimization toolbox)

Hi,

I have been using OPT++ to solve a non linear programming problem. I
am totally new to C++, but I looked at an example given on OPT++
website and modified it according to my problem. But I am getting some
error there.

Since I don't have analytical derivatives, I am using FDNLF1 type of
problem and optimization method used is OptFDNIPS. I am getting
problem in the input arguments(function, constraints etc) of FDNLF1
which I constructed the way it is done in the example on opt++ website
(http://csmr.ca.sandia.gov/opt++/opt++2.4_doc/html/example2.html). But
that example uses NLF2 type of problem. Since I am totally new to C++,
I have no idea what is causing these errors. The error that I am
getting is :

Is there anyone who has used this package(OPT++) and solved a non-
linear problem(non-linear objfun and constraints) without analytical
gradients. I would appreciate any help in this regard. Even an example
code for a general non-linear problem will help.

Thank you

Your problem is on line 24 of example2.cpp

you are making a call to the function FDNLF1, passing it parameters
that do not match any existing FDNLF1 definitions.

Thanks. I had an idea that problem is there. But in the error message
it is saying that I have passed int&(which I have no idea of) as the
first parameter. But I passed it an 'int' and not an int&. And in
other parameters also, I passed void () function, but here it says I
passed void(&). Any suggestions on this ?

Thanks
