Forum: wxRuby OS X Snow Leopard + wxRuby 2.0.1 gem - WORKING

Hi

It is possible to use the standard wxRuby 2.0.1 gem with the standard
system ruby in /usr/bin/ruby in OS X 10.6

1) download the gem

http://rubyforge.org/frs/download.php/63386/wxruby...

2) install it from the downloaded file

sudo gem install wxruby-2.0.1-universal-darwin-9.gem

3) run ruby like this, forcing 32-bit mode

arch -i386 ruby -rubygems <scriptfile.rb>


Have tested with a couple of samples and this works fine. Appreciate any
feedback. Of course, we are still aiming to get full compatibility, but
for various reasons this is quite difficult.

Thanks to some advice on this page (comment #4)

Thanks Alex.

Tested it with my app on Snow Leopard, it started OK until "require 
'nokogiri'"

Here is output:

/Library/Ruby/Gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.bundle: 
dlopen(/Library/Ruby/Gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.bundle, 
9): no suitable image found.  Did find: (LoadError)
        /Library/Ruby/Gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.bundle: 
mach-o, but wrong architecture - 
/Library/Ruby/Gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.bundle


I guess that's because Nokogiri is built with 64-bit.

Zhimin

That would be correct, you would need a 32 bit copy of nokogiri, in 
order
for it to work properly.

Alex & Mario,

Yes, My app now works on Snow Leopard (after using 32-bit nokogiri), 
Thanks!

Regards,
Zhimin

Sweet. Runs perfectly on my 10.6.4 machine.

Did anyone manage to launch the 32bit ruby environment from Netbeans?

Thanks,
Tony

Some good news...

Alex, your method didn't work for me immediately but I found a method
that works for me and may help others.

I have a MacBook Pro (64-bit) running OS X 10.6.
Like others, I wanted to run Ruby 1.9.2 (latest) and wxRuby 2.0.1
(latest).

I use RVM to install Ruby 1.9.2 (and manage my ruby versions).
(See http://pragmaticstudio.com/blog/2010/9/23/install-...)

By default, RVM builds the Ruby 64-bit version (only).
I finally found a post that indicates how to build both 32-bit and
64-bit versions of Ruby.

Briefly, here's how users can get both built:
rvm install ruby-1.9.2-head -C --with-arch=x86_64,i386

Here's how to check what you have:
file `which ruby` | perl -pe 's|^.*/||'

(Which will produce output like this:)
ruby: Mach-O universal binary with 2 architectures
ruby (for architecture x86_64): Mach-O 64-bit executable x86_64
ruby (for architecture i386):   Mach-O executable i386

Visit:
http://rubyforge.org/frs/?group_id=35

And, download this gem:
wxruby-ruby19-2.0.1-x86-darwin-9.gem

Now, install the gem (no sudo required):
(Note, you may want to cd to your Downloads folder.)
gem install wxruby-ruby19-2.0.1-x86-darwin-9
Successfully installed wxruby-ruby19-2.0.1-x86-darwin-9

Create a wxruby test script (wxtest.rb):
------------------------------------
#!/usr/bin/env arch -i386 ruby

require 'wx'
include Wx

App.run do
  frame = Frame.new(nil, :title => 'So far, so good...')
  frame.show
end
------------------------------------

And run it:
> ruby wxtest.rb


Ok, so this particular working set produced a window.
So, we (or I anyway) have a way to proceed.

Alex - I hope this somehow helps you find out what the problem
(32-bit vs 64-bit) might be.  Any thoughts?

Cheers,
Ridge

That sounds similar to my setup.

I hadn't come across RVM - this looks great.

I'm just headed off for xmas so won't have a go at this til new year -
but it sounds very promising as a way to restart development on the
stable branch with 10.6. What I'll need to test is that I can use this
ruby to compile against wxWidgets 2.8 - which is what has been the
headache so far.

best wishes
alex
