I have fedora Core 5 running on two machines (both pentium 4 dual boot machines). I have installed ruby (ruby 1.8.4 (2005-12-24) [i386-linux]) and ruby tk (ruby-tcltk-1.8.4). When I run irb and add require 'tk'. This is the error message I receive. /usr/lib/ruby/1.8/tk.rb:1102: warning: Inconsistency. Loaded Tcl/Tk libraries are enabled nativethread-support. But `tcltklib' is not. The inconsistency causes SEGV or other troubles frequently. This error is present on both machines. Is there some way of correcting this problem. thanks -- Ed Redman AAC Forest Lakes Dartmouth Region redman / accesswave.ca
