To link your program to the callable library, make sure you have included the header file symphony.h in all the source files that call SYMPHONY functions. Also, make sure that your include path contains the directory where all of SYMPHONY's header files are stored. Then simply include the appropriate SYMPHONY library in the set of libraries to be linked and make sure that the path to the library is in the library path. Example makefiles For Unix-like environments are included in the Examples/ directory.
