Preparing for Sample Compilation.

• Download the file SYMPHONY-5.0.tgz.

• Unpack the distribution with tar -xzf SYMPHONY-5.0.tgz. This will create a subdirectory called SYMPHONY-5.0 containing the distribution.

• Edit the makefile (SYMPHONY-5.0/Makefile) to reflect your environment. This involves specifying the LP solver to be used, assigning some variables and setting the paths to various libraries and include files.Only minor edits should be required. An explanation of what has to be set is contained in the comments in the makefile.

• To use many of the new capabilities of SYMPHONY, you must have installed the COIN optimization libraries . By default, SYMPHONY is set up to use COIN LP solver, CLP, COIN Open Solver Interface, OSI, and COIN Cut Generation Library, CGL. To keep this configuration, you should install OSI, CGL, CLP and the Coin utilities (under COIN/Coin). The path to the COIN libraries must be specified in SYMPHONY-5.0/Makefile. If you want to use the new OSI interface to SYMPHONY, you should be sure to compile it when you are installing the rest of the COIN packages.

• If you wish to read GMPL/AMPL files, you will have to install the Gnu Linear Programming Kit (GLPK), which contains a parser for GMPL/AMPL files. The path to the GLPK libraries must also be specified in SYMPHONY-5.0/Makefile.
