Preparing for Sample Compilation.

• Download the file SYMPHONY-4.0.tgz.

• Unpack the distribution with tar -xzf SYMPHONY-4.0.tgz. This will create a subdirectory called SYMPHONY-4.0/ containing the distribution.

• Edit the makefile (SYMPHONY-4.0/Makefile) to reflect your environment. This involves specifying the LP solver to be used and 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 . Specifically, you should install OSI, CGL, and the Coin utilities (in the COIN/Coin directory). If you want to use the COIN LP solver, you should also download CLP. The path to the COIN libraries must be specified in SYMPHONY-4.0/Makefile.

• 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 be specified in SYMPHONY-4.0/Makefile.
