Hi all,

Has anyone successfully run any of their Gosu projects under the version of Ruby (1.8.7) which ships with Snow Leopard?

After getting my Mac upgraded and whatnot, I installed the 0.7.14 gem and finding that when I try to run any game (my own, as well as the tutorials), I happen to get the following error appear in the output…

/Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in gem_original_require': no such file to load -- /Library/Ruby/Gems/1.8/gems/gosu-0.7.14-universal-darwin/lib/gosu.bundle (LoadError)
  from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in require'
  from /Library/Ruby/Gems/1.8/gems/gosu-0.7.14-universal-darwin/lib/gosu.rb:10

  from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:36:in require'
  from CptnRuby.rb:35

Just wondering if there's something messed up with my configuration, or if I've missed something to getting it all up and running.

[EDIT]
NB: Did a bit more of an investigation. My Mac's running Ruby in 64-bit, and I'm not sure, but it looks like gosu's built for 32-bit Intel/PPC only.  I'll investigate and see if I can get it to build 64-bit locally for me and see if this fixes it.

Oh man, I totally forgot about this. My MacBook (Pro) has been such a pain lately that I didn't even upgrade yet.

No, Gosu does not build in 64-bit and this is horrible. I hope the Ruby 1.9 Wrapper app still works. The problem is that I have no 64-bit replacement for some of the functions, I should probably just release a stripped down version ASAP. (It's mostly button_id_to_char and vice versa.)

Thanks for reminding me :)

No worries about the reminder - glad to know that it's not a configuration screw-up or the likes on my end.  I'm happy to wait for a proper release in due time.

I'm happy to give the 1.9 stuff a whirl - I'll just need to see if I can get a 1.9 build on my Mac that's 32-bit only.  If I do I'll post somewhere to let you know :)

It would be great if you could just try the 1.9 .app package from the Google Code download page (don't need to modify it, it should open an empty window):

http://code.google.com/p/gosu/downloads/list

I built this one as a self-contained Ruby distro for deployment, to prevent all sorts of trouble like the 64-bit change :)

For development, it's a pain of course, and I'm currently patching Gosu to use APIs that are available on 64-bit Cocoa. If all goes well, I can upload it tomorrow.

Woohoo, great news, the 1.9 wrapper seems to work on SL. Yay for an existing hotfix.

Yup, got it running on my end as well.

As a temporary work around, I should just be able to drop my code and resources into a copy of that 1.9 standalone bundle, then test it by just firing up the whole bundle then?

That'll be enough to tide me over until some fixes are available.

Thanks again :)

gosu from gem install gosu works just fine out of the box in snow leopard with ruby 1.8.7 if you start ruby in 32 bits mode.
$ arch -i386 ruby mygame.rb

Thanks a lot guys! The tip from manne just worked. :)

:(

I don't think I've ever had so much frustration with computers in years. Did anyone already upgrade to SL and feels like just fetching the 1.9 source tarball from ruby-lang.org, then running "./configure --enable-shared --program-suffix=1.9 && make", then posting/sending me the libruby-1....dylib? I can't get a 64-bit Ruby compiled on Leopard no matter what I throw at configure and make, and I need a lib like that for the Snow Leopard gem. Or maybe I can manage to build a gem with just five of the six combinations (i.e. no 64-bit 1.9 support), but that sounds ugly too.

Thanks :)

Thanks to a quick & kind contribution by Paulo, here is my experimental three-way Universal gem: http://www.raschke.de/julian/temp/gosu-0.7.15-universal-darwin.gem

Can anyone on SL download, then 'sudo gem install' it, and then run the Tutorial.rb example? (cd /Library/Ruby/Gems/1.8/gems/gosu-0.7.15-universal-darwin/examples && ruby Tutorial.rb if the Gem path is still the same on SL.)

Yup, all working now! Thanks Julian!

Paulo

Awesome! :) Did the score text in the corner render correctly too? (That's what I had to rewrite for SL)

I'll try to push the gem out in the next hours.

The text do not render on snow leopard...

Thanks, I hope I won't mess everything up with my current plans on how to fix this :)

*boots up Xcode…*

For what it's worth, the above gem works for me on Snow Leopard with Ruby 1.8.7 installed from ports. However, as above, I don't see any text in the Tutorial.rb example.

Edit: I spoke too quickly. After running a game in full screen mode, it crashes when exiting. I've boiled the code down to the following, which crashes on exit:

  require 'rubygems'
  require 'gosu'
  class GameWindow < Gosu::Window
    def initialize
      super(800, 600, false)
    end
    def update
      exit
    end
    def draw; end
  end
  GameWindow.new.show

The error message is:

It doesn't seem to matter what resolution is used, and the above code doesn't crash in windowed mode.

shawn42 also encountered this behaviour on macosx (i dont think he's running snow leopard)

Thanks everyone for the reports, I hope I fixed all of these bugs and uploaded the new 0.7.15 gems. Will make the release official soon, but if anyone wants to try them out now, that would boost my confidence that the fix actually worked this time :)

I tried some unit tests I have on a small project. They don't open a display but they didn't complain that something was broken, as they did with 0.7.14
I can't do any real testing until tomorrow.

Can happily report that the new gem works just fine. And this time I even tested it by opening a window. :P
(Well, I played a few turns of Mr Monocle...)
