SNAP works under Windows with Visual Studio or Cygwin with GCC, Mac OS X, Linux and other Unix variants with GCC. Make sure that a C++ compiler is installed on the system.

SNAP is largely self-contained and requires external packages only for drawing and visualization. The following packages need to be installed on the system to support drawing and visualization in SNAP:

• Gnuplot for plotting structural properties of networks (e.g., degree distribution);
• Graphviz for drawing and visualizing small graphs.

Set the system PATH variable, so that Gnuplot and Graphviz are available, or put the executables in the working directory.

SNAP Components

The SNAP distribution package contains the following components:

• snap-core:the core SNAP graph library;
• snap-adv:advanced SNAP components, not in the core, but used by examples;
• snap-exp:experimental SNAP components, still in development;
• examples:small sample applications that demonstrate SNAP functionality;
• tutorials:simple programs, demonstrating use of various classes;
• glib-core: STL-like library that implements basic data structures, like vectors (TVec), hash-tables (THash) and strings (TStr), provides serialization and so on;
• test:unit tests for various classes;
• doxygen:SNAP reference manuals.
