	Re: Warning from FXRuby by Lyle Johnson-4 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Thanks for the information, David. Yes, it looks like for whatever reason I've got a weird combination of tabs and spaces for the indentation in that part of the file; that can be easily fixed. Since they are just warnings, you can presumably ignore them until I get a patched version out. Looks like Ruby 1.9.1 is more picky about indentation, which is kind of an interesting change... I'm also glad to see that it (apparently?) built without any problems. I don't think a lot of folks are playing with Ruby 1.9.1 yet, much less trying FXRuby with it. I know that I'm still seeing a few unusual things with FXRuby under Ruby 1.9.1, so please let me know what you observe.

Or, as the log suggests, is this a bug in Ruby 1.9.1? I am seeing a lot of this. I would classify it as a problem with FXRuby on Ruby 1.9.1, although it's due to a change (or changes?) in the garbage collection implementation for Ruby 1.9.1. I am not sure what it's going to take to fix it at this point, but patches are welcome from anyone who has more time to look at this than I do at the moment. _______________________________________________ fxruby-users mailing list fxruby-users@... http://rubyforge.org/mailman/listinfo/fxruby-users
