How to use CPLEX? #90

Closed gguillot closed 2 years ago

gguillot commented 2 years ago

Hi, I want to use CPLEX instead of SYMPHONY, I changed the config file, but I can't link the solver. Do you know what needs to be changed to link the solver?

Thank you.

Assuming you are building from source with coinbrew, you have to tell MibS where to find CPLEX. For example, I build as follows on our cluster. 

coinbrew build MibS --with-cplex-incdir=/usr/local/cplex/include/ilcplex --with-cplex-lib="-L/usr/local/cplex/lib/x86-64_linux/static_pic/ -lcplex -lpthread -lm"

Then, set the solver to CPLEX with the option -MibS_feasCheckSolver CPLEX. Let me know how it goes.

I'm going to move this to a Discussion instead of an Issue, since it's more of question than a problem.
