[OS] Linking with OS API

[pete]

Dear all,

I am planning to write global optimization solvers which use OS to
read in
.nl model instances. I have built OS on my Linux machine, but have
been
having difficulties including/linking to the OS API. Say for instance

#include <stdio.h>
#include "OSInstance.h"
#include "OSnLNode.h"
#include "OSnl2osil.h"
#include "DefaultSolver.h"
#include "IpoptSolver.h"
#include <vector>
#include <math.h>

using namespace std;

int main(int argc, char **argv) {
  OSInstance *osinstance;
  OSnl2osil *nl2osil = NULL;
  DefaultSolver *solver = NULL;

  osinstance = new OSInstance();
}

it seems that not only do I have to specify the include path to the
"include"
folder created after installation, but a host of other folders
associated with
other COIN-OR or ThirdParty projects. In addition I compile errors
would
come up due to #error, preprocessor statements, forcing me to define
variables
such as -DHAVE_MATH_H -DHAVE_TIME_H.  Similar difficulties were
encountered
during linking.

Is it normal to do this in order to get it to work? Is there a better
way?

I am sure I have done something silly. Could any of you point me to a
good tutorial
or example on using the COIN-OS API. I have been reading the User's
Manual but it
did not cover this aspect.
