Hi,

I am using CPLEX with Windows server 2003 X64 system. However, I am not able to install Visual Studio on this computer, due to some restrictions on the user's rights. Then, following a previous topic, I have tried to compile .cpp files by myself, using MinGW and gcc.
CPLEX can be used in C++, regardless of the compiler/editor you choose.

I took a modified Linux Makefile reported below.
SYSTEM    = x64_.net2005_8.0
LIBFORMAT  = stat_mda

#------------------------------------------------------------
#
# When you adapt this makefile to compile your CPLEX programs
# please copy this makefile and set CPLEXDIR and CONCERTDIR to
# the directories where CPLEX and CONCERT are installed.
#
#------------------------------------------------------------

CPLEXDIR      = C:\ILOG\CPLEX102
CONCERTDIR    = C:\ILOG\Concert24
# ---------------------------------------------------------------------
# Compiler selection
# ---------------------------------------------------------------------
CCC = gcc

# ---------------------------------------------------------------------
# Compiler options
# ---------------------------------------------------------------------

CCOPT = -m32 -O -fPIC -fexceptions -DNDEBUG -DIL_STD

# ---------------------------------------------------------------------
# Link options and libraries
# ---------------------------------------------------------------------

CPLEXBINDIR  = $(CPLEXDIR)\bin\$(BINDIST)
CPLEXJARDIR  = $(CPLEXDIR)\lib\cplex.jar
CPLEXLIBDIR  = $(CPLEXDIR)\lib\$(SYSTEM)\$(LIBFORMAT)
CONCERTLIBDIR = $(CONCERTDIR)\lib\$(SYSTEM)\$(LIBFORMAT)

CCLNFLAGS = -L$(CPLEXLIBDIR) -lilocplex -lcplex -L$(CONCERTLIBDIR) -lconcert -m32 -lm -lpthread

all:
nmake all_cpp

CONCERTINCDIR = $(CONCERTDIR)\include
CPLEXINCDIR  = $(CPLEXDIR)\include

EXDIR        = C:\ILOG\CPLEX102\examples
EXSRC        = $(EXDIR)\src
EXINC        = $(EXDIR)\include
EXDATA        = $(EXDIR)\data

CCFLAGS = $(CCOPT) -I$(CPLEXINCDIR) -I$(CONCERTINCDIR)

#------------------------------------------------------------
#  make all      : to compile the examples.
#------------------------------------------------------------


CPP_EX = ilodiet
         
all_cpp: $(CPP_EX)

# ------------------------------------------------------------

#clean :
# /bin/rm -rf *.o *~ *.class
# /bin/rm -rf $(CPP_EX)
# /bin/rm -rf *.mps *.ord *.sos *.lp *.sav *.net *.msg *.log *.clp

# ------------------------------------------------------------
#
# The examples
#

ilodiet: ilodiet.o
$(CCC) $(CCFLAGS) ilodiet.o -o ilodiet $(CCLNFLAGS)
ilodiet.o: $(EXSRC)\ilodiet.cpp
$(CCC) -c $(CCFLAGS) $(EXSRC)\ilodiet.cpp -o ilodiet.o



However, I am getting the following error:
C:\ILOG\CPLEX102\examples\src\ilodiet.cpp:1: warning: -fPIC ignored for target (all code is position independent)
In file included from C:/ILOG/Concert24/include/ilconcert/iloenv.h:14,
                from C:/ILOG/Concert24/include/ilconcert/iloalg.h:14,
                from C:/ILOG/Concert24/include/ilconcert/ilomodel.h:14,
                from C:/ILOG/CPLEX102/include/ilcplex/ilocplex.h:19,
                from C:\ILOG\CPLEX102\examples\src\ilodiet.cpp:31:
C:/ILOG/Concert24/include/ilconcert/ilosys.h:255:23: generic.h: No such file or directory

Could you confirm than I am able to use any editor? May I have further information regarding compilation if Visual Studio is not used?

Regards,
Alexis C.

You have to use a compiler that is compatible with VC++ in order to use the Concert C++ API.  I don't think gcc/MinGW is compatible.

Thank you for your reply. I haven't notice than MinGW is not compatible with VC++. I finally ask for a Visual studio version, which will take some time.

It is possible to use the C API with MinGW and CPLEX. But I don't know about Concert library.

Try using this compiler option:

CCOPT = -m32 -O -fPIC -fexceptions -DNDEBUG -DIL_STD -DILO_MSVC

Try also using a different SYSTEM (possible systems are in the C:\ILOG\CPLEX102\lib directory):

SYSTEM = msvc7

Hi,

I'm using CPLEX with Windows XP. I'm trying to compile my C++ program using gcc in MinGW but getting a lot of linking errors, each of which indicates an undefined reference to functions in CPLEX, for example:

undefined reference to 'operator+(IloNumExprArg, IloNumExprArg)'

I'm linking my program to the libraries ilocplex and cplex111 in x86_.net2005_8.0\stat_mda in CPLEX111\lib, and also to concert in x86_.net2005_8.0\stat_mda in Concert26\lib.

Does anyone have any idea why I'm getting those linking errors? Is it because the libraries are not compatible with MinGW?

Thanks,
CT
