Hi all, Mprime version 19.1 is now available. The only new feature of any consequence is a solution to the error 2250 some users of the staticly linked mprime suffered. The whatsnew.txt file describes the line you need to put in primenet.ini. You must create the primenet.ini file. Many thanks to all that helped narrow the problem down to a difference in the way gethostbyname call worked in different versions of the OS. Regards, George P.S. P-1 factorers - do not use the Stage1GCD undocumented feature. It may have a bug. _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
