This chapter shows the steps to get a working version of Marsyas. Compiling and installing a large piece of software like Marsyas is not trivial. In the summer 2008 we switched our build system from a combination of autotools and qmake to using CMake. We believe that this change has greatly simplified the building process across all supported platforms and configurations. Starting with the Belfast release 0.2.17 CMake is the only supported way to build Marsyas.
