Please note that the library may not be used in closed-source commercial software projects (whether linked statically or dynamically). If you are interested in commercial licenses, or have further questions on licensing, please contact license@ogdf.net.

The library can be compiled for various platforms. We tested it on Linux and MacOS X using the gcc C++ compilers, and on Windows using the Microsoft Visual C++ compiler. See System Requirements for details. The software may also work under other operating system / compiler combinations, e.g., UNIX systems with gcc compiler.

You will also need to have Python 2.6 or 2.7 installed for creating a makefile.

Installation instructions can be found here:

• Linux / Mac OS X (gcc compiler)
• Windows (Visual C++ compiler)

For viewing GML files produced by OGDF, you can use the GoVisual Diagram Editor (GDE) as graph editor. We are aware that it is a bit old and not updated for a while (especially the Linux version might not work on your Linux); we hope to have something new soon.
