On OS X, you can find the samples that installed with the gem at: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/user-gems/1.8/gems/wxruby-1.9.5-universal-darwin-9/samples/ basically you want just require “rubygems” require “wx” at the start of your script. > I’ve installed “wxruby-1.9.3-universal-darwin” the latest gem version is 1.9.6; I recommend you install that. There are dedicated mailing lists for wxruby questions: [http://wxruby.rubyforge.org/wiki/wiki.pl?MailingLists](http://wxruby.rubyforge.org/wiki/wiki.pl?MailingLists) alex ---

Thanks for all. i’ve installed wxruby by gem: $ sudo gem install wxruby then i wonder why i didn’t get the latest version… i’ll uninstall and re-install after download. also at the time being i get : ruby /opt/local/lib/ruby/gems/1.8/gems/wxruby-1.9.3-universal-darwin/samples/ minimal/minimal.rb dyld: NSLinkModule() error dyld: Library not loaded: /usr/lib/libiconv.2.dylib Referenced from: /opt/local/lib/ruby/gems/1.8/gems/wxruby-1.9.3-universal-darwin/lib/wxru by2.bundle Reason: Incompatible library version: wxruby2.bundle requires version 7.0.0 or later, but libiconv.2.dylib provides version 5.0.0 zsh: trace trap ruby this is because (?) my ruby install has been done thru MacPorts: $ which ruby /opt/local/bin/ruby $ ruby --version ruby 1.8.6 (2007-09-24 patchlevel 111) [powerpc-darwin8.11.0] and the dylib is under /opt : $ locate libiconv.2.dylib […] /opt/local/lib/libiconv.2.dylib […] for those reasons i think it’s best for me to compile wxruby ? ---

Maybe, it’s not hard if you have XCode installed. Unless you want to use advanced features like OpenGL or Scintilla, you just compile wxWidgets (./configure; make; make install) and then wxRuby (rake; then either rake install or rake gem) [http://wxruby.rubyforge.org/wiki/wiki.pl?InstallingFromSource](http://wxruby.rubyforge.org/wiki/wiki.pl?InstallingFromSource) [http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets](http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets) a ---

All recent versions are specifically built to be compatible with 10.4 or 10.5. Unfortunately about the same time rubygems became more pedantic about compiler versions, which is why I guess you’re not getting offered the latest via remote gem install. I suggest you download it from here: [http://rubyforge.org/frs/?group\_id=35](http://rubyforge.org/frs/?group_id=35) and install locally (“sudo gem install wxruby” in the folder where the downloaded gem is saved). if you have any further problems, please follow up on the wxruby-users mailing list. a
