Here is a sketch outline of how to compile SYMPHONY in MS Windows with the MSVC++ compiler. These instructions will lead you through the steps required to compile SYMPHONY as a generic MILP solver. Note that the Windows version has some limitations. Detailed timing information is not currently provided. Support is only provided for running in sequential mode at this time.
First, obtain the source code by downloading from https://www.coin-or.org/download/source/SYMPHONY/. Unpack the archive to create the directory SYMPHONY-5.2.3. You now have three options. You can either build using the MSVC++ IDE, build on the command-line with MSVC++ compiler, or use the NMAKE utility.
