Hi all,

Can someone tell me how I can “reconfigure and recompile” Couenne to use Cplex for lp solver?

I added this to couenne.opt “lp\_solver cplex” and read in teh manual that I need to run the configuration file after adding these lines:

–with-cplex-lib=“/your/path/to/libcplex.a -lpthread”  
–with-cplex-incdir=C:\Program Files\IBM\ILOG\CPLEX\_Studio129\cplex\include\ilcplex

I assume this is for linux. How about in windows?

Thank you in advance!

If you’re on Windows, it’s likely going to be difficult.

I don’t have any experience with this, so not much help, but if your problem is a MINLP, you should consider using [GitHub - lanl-ansi/Juniper.jl: A JuMP-based Nonlinear Integer Program Solver](https://github.com/lanl-ansi/Juniper.jl).

Thanks for the tip! I will take a look at Juniper.
