No problem. You should be able to compile the bayes_net_gu_ex in visual studio or mingw (and even cygwin now). In fact, I use it in Windows XP all the time. But I guess you are having trouble getting it compiled in Windows XP still? -Davis On Thu, Jul 24, 2008 at 10:43 PM, Nabeel Alzahrani <nza...@ho...> wrote: > Thank you so much for your help.
