Hi guys
I don't have write permissions under /opt/cplex122, so I couldn't build the example files on a Linux machine. I just copied a few lines into a file ilocpp.cpp:

#include <ilcplex/ilocplex.h>
ILOSTLBEGIN
int
main (int argc, char **argv)
{
   IloEnv env;
   try {
      IloModel model(env);
      IloCplex cplex(env);
        }
        catch(Exception ex)
        {
        }
}

Based on the command line spitted by the Makefile for the examples, I then used the following command to try and build the file:

g++ -c -m32 -fPIC ilocp.cpp -I/opt/cplex122/cplex/include -I/opt/cplex122/concert/include -Wno-deprecated -o ilocpprb -D ILO_LINUX -D ILOSTRINGSTL -D ILO_USESTL

However, I get a compilation error. It says:

/opt/cplex122/concert/include/ilconcert/ilosys.h:402:23: error: strstream.h: No such file or directory

I looked at ilosys.h, and as you can see, I tried to define a few pre-processor symbols to try and force the compiler to

#include <strstream> 
instead of 
#incldue <strstream.h>

What to do?
Thanks and best regards

I think the only -D-option you need is '-DIL_STD'. Does this work?

g++ -m32 -fPIC -I/opt/cplex122/cplex/include -I/opt/cplex122/concert/include -DIL_STD -Wno-deprecated -c -o ilocpprb.o ilocpp.cpp

You can also copy the examples to a place at which you have write permission and compile them there.
