Hello, I just put preview4 archive on the ftp server. I'm sure we still have problems left. Braves, try and find errors, on as many platforms as possible, please. ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.0-preview4.tar.gz I will submit preview5 on Monday 8:00am UTC. The final 1.8.0 will be available on either 30th or 31st, as I hope. matz. p.s. To IA64 users: it is reported that you need to change optimize flag to "-O0" to compile on IA64 machines.
