At the time ILOG's Concert library was first released, the older iostream.h headers were still common in C++ compilers, but it supports the standard iostream libraries. To use the standard headers and libraries, you need to define the IL_STD preprocessor symbol. Instructions for defining preprocessor directives in Eclipse/C++ can be found in this question.
error: iostream.h due to including cplex

Question
I am trying to use cplex in eclipse in Ubuntu 12.04 but when I include ilocplex.h I get the following error
/opt/ibm/ILOG/CPLEX_Studio124/concert/include/ilconcert/ilosys.h:360:22: fatal error: iostream.h: No such file or directory
The only two includes are written as follows:
#include <ilcplex/ilocplex.h>
#include <iostream>
I would appreciate if anyone could help me with this.
Solution
OTHER TIPS
Try reading the manual again or look again at the samples. Cplex has supported both the old style iostream.h and the newer C++ iostream standard for at least a decade. I just don't have the manual with me right now to give the full reference.
