在Linux上的Eclipse C ++中设置CPLEX

Question

I have installed CPLEX 12.6.3 (CPLEX_Studio_Community1263) and I want to integrate CPLEX in my Eclipse C++ project (on Linux). But I don't know which steps I have to follow to include CPLEX in my project.

Even by following exactly the steps shown at this link , it still not working for me (I can't import cpelx.jar in my project). The path of my cplex.jar is

/opt/ibm/ILOG/CPLEX_Studio_Community1263/cplex/lib/cpelx.jar

When I right-click on my project and go to

Properties --> Settings --> GCC C++ Linker --> Libraries

to add the cplex.jar in my project, it is impossible to add the .jar because I can't select it (it is deselected and impossible to select it).

Can some one explain me how I can include CPLEX in my project?

Answer 1

The link you reference is for setting up a Java program. This will not help you.

Instead, you should try running one of the C++ examples shipped with CPLEX. Try the following (assuming your path is correct from above):

$ cd /opt/ibm/ILOG/CPLEX_Studio_Community1263/cplex/examples/x86-64_linux/static_pic
$ make ilolpex1 2>&1 | tee output.txt

This will save the output in output.txt so that you can look at it later. It should give you an idea of what the required command line arguments are.

For example, on my system (x86-64_linux), I see this in the output:

$ make ilolpex1
g++ -O0 -c -m64 -O -fPIC -fno-strict-aliasing -fexceptions -DNDEBUG -DIL_STD -I../../../include -I../../../../concert/include  ../../../examples/src/cpp/ilolpex1.cpp -o ilolpex1.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 ilolpex1 ilolpex1.o -lconcert -lilocplex -lcplex -lm -lpthread

This tells you everything you need to know to compile and link your program. You'll just need to figure out where to enter this information in Eclipse.
