[Bonmin] Setting up Bonmin 1.8.7 with CPLEX 12.9

Mon Jul 1 10:04:41 EDT 2019

In WSL, you are really building in Linux so you need to link to the Linux
libraries, not the Visual Studio ones. If you want to link to Visual Studio
libraries, you can follow the instructions for building under Msys2, but
you will either need a Visual Studio compatible Fortran compiler (like
Intel's ifort) or figure out how to make libraries built with MinGW
compilers (Windows port of gcc and gfortran) link to Visual studio (this is
possible, but a bit difficult and I have never tried it).

Once you install Msys, you will get another bash installed (make sure it
comes first in your path). You just need to have the Visual Studio compiler
and your Fortran compiler in the Windows Path, then you can build using the
same incantation except that you need to add the argument --enable-msvc to
coinbrew.

Let us know how it goes.

Cheers,

Ted
