Using the MSVC++ Workspace

• In MS Visual C++ 6.0, open the workspace SYMPHONY-5.0 $\backslash$USER $\backslash$WIN32 $\backslash$user.dsw. Note that there are two projects, one called symphonyLib and the other called user.The symphonyLib project compiles the source code, with the calls to the user-defined callbacks used to customize the solver, to create the callable library: symphonyLib.lib. The user project compiles those user callbacks together with the main function, links them with the callable library and creates the executable: user.exe.

• The configuration steps are exactly the same with the MSVC++ section of SYMPHONY. The only difference is that, you have the user project instead of the symphony project. Go through the related steps of section 5.2 to see how to configure to use COIN, OSI, CGL, COIN utilities, GMPL input, and to change the lp solver which is by default CLP.

• Once you have the proper settings for your LP solver, choose Build user.exe from the Build menu. This should successfully build the executable.

• To test the executable, right click on the user project, go to the Debug tab and set the program arguments to -F .. $\backslash$sample.mps. Note that command-line switches are Unix-style.

• Now choose Execute from the build menu and you have a working branch and bound solver! After successful compilation, you can fill in the user callback functions as describe in SectionSYMPHONY-development.
