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.
Apparently
cplexis utterly outdated,iostream.hpredates every C++ standard.At the time ILOG's Concert library was first released, the older iostream.h headers were still common in C++ compilers,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.
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.
