HI, I have spent a couple of days trying to get the Fox GUI library to interact with ruby. Now I think I am getting close. Before I go on to explain my problem here is some information that may be necessary. ## System Information: MAC OS X Tiger 10.4.8 iBook G4 ## Software Versions: Ruby 1.8.1 FXRuby 1.6.5 Fox 1.6.21 RubyGems 0.9.1 Fox and FXRuby, when compiled they say they compiled succesfully, I have also recompiled FXRuby with RubyGems, all being successful. I then go into irb and type require ‘fox16’ and I get this message returned: /sw/lib/ruby/site\_ruby/1.8/powerpc-darwin/fox16.bundle: [BUG] Bus Error ruby 1.8.1 (2003-12-25) [powerpc-darwin] Abort trap Console Prints out this message at the same time: Feb 3 15:10:14 zane-ibook-g4 crashdump[15431]: ruby1.8 crashed Feb 3 15:10:16 zane-ibook-g4 crashdump[15431]: crash report written to: /Users/ZaneV/Library/Logs/CrashReporter/ruby1.8.crash.log When I try require ‘fox’ in irb I get this message: LoadError: No such file to load – fox from (irb):1:in `require’ from (irb):1 But I take it that as long as I can get fox16 working then this won’t be a problem. I have trawled through website after website trying to find a fix to this problem or some helpful information… I have have read a heap of FXRuby documentation and some Ruby Documentation. Please help, Thanks, Zane.

I have a hunch that that interface has changed a bit since Ruby 1.8.1 (which is several years old now). My advice is to upgrade to the most recent version of Ruby (1.8.5), and then recompile FXRuby and try again. You shouldn’t need to recompile FOX – just zap your FXRuby build directory and recompile that part. Good luck, Lyle ---

Actually, I don’t understand why… I found why .ext is not created. If you do: ./configure && make then it is created, but if you do: ./configure && make test it is not created. So, you must do: ./configure && make && make test && make install as stated by the README file. I’m surprised by this behavior since generally the test rule depends on the “build” rule. Cheers, ---

If you didn’t specify --prefix to the configure script it uses /usr/local as default value. Cheers, ---

Or does this indicate another problem? When I type: > > ruby --version It still prints out: 1.8.1. I have also noticed I have 3 ruby directories: /sw/lib/ruby/1.8 /usr/lib/ruby/1.8 /usr/local/lib/ruby/1.8 The first directory (/sw/lib/ruby/1.8) I think is the original(1.8.1) because I remeber seeing it there before attempting to install version 1.8.5. I know that the last directory (usr/local/lib/ruby/1.8) is the new one which was created when attempting to install 1.8.5 and I am not sure about the second directory (/usr/lib/ruby/1.8), wether it is new or old. Anyways, I am making a bit of progress now and thanks a lot for all your help so far. ZaneV
