Requirements for compiling AFD AFD only works with UNIX or MacOS (the newer ones based on Unix) AFD has been run successful under the following Unix flavors: Linux, Solaris, HP-UX, Irix, Aix, FTX and SCO One can compile AFD under Windows with the help of cygwin, but it does not run. (Last try approx. 2 years ago) What works is Microsoft Unix subsystem INTERIX (http://en.wikipedia.org/wiki/Interix). With it AFD runs. However, it seems that Microsoft has ceased development of Interix.
