Hello Dear, I am using the C ++ API for CPLEX 12.9 in Linux / Centos and I perform the execution and linking of the dependencies as follows:

But I cannot generate the compiled one I get several errors. Will I be linking the dependencies well?

regards!

Hello,

hard to answer without knowing the errors. However you can try to compile one of the delivered examples. If it doesn't work then give us please the error messages. Otherwise you can copy the compilation options.

To compile delivered examples go to cplex/examples/x86-64_linux/static_pic inside your installation. And there you can compile all examples by typing just "make". Or you can compile one of the examples that are using Concert (it seems you'r using it too) by e.g. "make fixcost1".

Dear Petr,

This is my error link. I trying to test my algorithm with make and don't work.

If you compile one of the delivered examples using the makefile shipped with cplex, you could see that the compilation is done the following way:

g++ -O0 -c -m64 -O -fPIC -fno-strict-aliasing -fexceptions -DNDEBUG -DIL_STD -I../../../include -I../../../../concert/include ../../../examples/src/cpp/fixcost1.cpp -o fixcost1.o

g++ -O0 -m64 -O -fPIC -fno-strict-aliasing -fexceptions -DNDEBUG -DIL_STD -I../../../include -I../../../../concert/include -L../../../lib/x86-64_linux/static_pic -L../../../../concert/lib/x86-64_linux/static_pic -o fixcost1 fixcost1.o -lconcert -lilocplex -lcplex -lm -lpthread -ldl

Note the the compiler is run twice: first to create object file, second to link. So I suggest to simply replace fixcost1 by name of your program, fix the paths in -I and -L options, and it should compile.

The errors you see are due to the missing -lconcert -ilocplex and -lcplex. The other options are important too though. I suggest to start with the exact copy and then make changes if necessary.

Hello Petr,

Thanks for your help and ideas. I saw the examples files like makefile and I understand several components for my syntax, and also including additional libraries at last of my line like -ldl.

This my line (work fine):

 g++ -std=gnu++11 -O0 -m64 -O -fPIC -fno-strict-aliasing -fexceptions -DNDEBUG -DIL_STD main.cpp vrp.cpp vrp.h -I/opt/ibm/ILOG/CPLEX_Studio129/cplex/include -I/opt/ibm/ILOG/CPLEX_Studio129/concert/include -L/opt/ibm/ILOG/CPLEX_Studio129/cplex/lib/x86-64_linux/static_pic -L/opt/ibm/ILOG/CPLEX_Studio129/concert/lib/x86-64_linux/static_pic -o hardprogram -lconcert -lilocplex -lcplex -lm -lpthread -ldl
