How can I catch segment faults?
by B. Ohr (dev) 21 Sep '09

21 Sep '09

Hey, after installing r2590 with backtrace support (thanks for that!) now I have the problem to catch segment faults. It seems to be a problem inside of a hash#each_pair, but I have absolutely no idea where, and because it is foreign code a file name and line number would be more than useful! ------- (gdb) run ../xx.rb compile Starting program: /usr/local/bin/macruby ../xx.rb compile Reading symbols for shared libraries + done Loading site data...

Nib issues on Snow Leopard

19 Sep '09

I'm trying to get a project that ran on MacRuby 0.4 and Leopard working with 0.5 on Snow Leopard. When I launch the app I get the following errors: 2009-09-15 20:08:08.954 TwittRb[87043:a0b] Unknown class 'TwittRbDelegate', using 'NSObject' instead.

super brief glimpse of trunk progress
by Matt Aimonetti 18 Sep '09

18 Sep '09

As you know, we are getting close to releasing 0.5 RC1 so I figured you might wonder about the latest progress happening in trunk. If you really want to give 0.5 trunk a spin and don't want to compile from source, Snow Leopard users with 64bit CPU can download the nightly builds: http://macruby.icoretech.org/ (the nightly web app has been put on GitHub by Claudio if you care to look at the source code). So what's new? Lots of bug fixes, macgem is getting closer to be ready. It's still slow but now you can require your gems by doing require 'game_name' instead of gem 'gem_name'; require 'gem_name'. The performance should be improved greatly once we know everything works well. Feel free to give it a try and report bugs in the tracker. Also, backtraces are almost back :) As of this morning, uncaught exceptions don't print the backtrace but if you want to give it a try, catch your exception and print its backtrace. Example: begin raise 'this is just a test' rescue Exception => e raise "#{e}\n backtrace: #{e.backtrace}" end However, as of next nightly build, macruby should have uncaught exceptions printing the backtrace. Exciting time coming up, get ready to test MacRuby 0.5 RC1 :)
