The library was developed and tested with the Gyro implementation of generics for C# (version from Aug. 23, 2002) on Windows XP. You will need the beta refresh version of the Rotor shared-source CLI implementation, not the 1.0 version or the version from Visual Studio.NET. The required version of Rotor is available here.
The source code for the graph library is in the gcs subdirectory, as well as a Makefile (tested using GNU Make under Cygwin). In order to build the graph library, you must link or copy the file gcollections.dll from the Gyro example directory samples/generics/gcollections/ after compiling in that directory. Several test programs are provided, and these are the executables which will be built by the Makefile.
