For the latest release there are currently binaries for Linux, Mac OS and Windows (i386 architecture) available.
If your operating system is not yet supported, i.e. there is no pre-compiled binary for your operating system available, you need to compile the GCX engine from source. If you need to compile it manually you will find ready-to-use Makefiles for Linux and Windows (Makefile.Linux/Makefile.Windows) in the src folder.
Note: If you want to compile the GCX engine from the sources using Mac OS you should use the Linux Makefile (Makefile.Linux).
Before manual compilation you should make sure that the following required (additional) tools are installed.
