wxruby users - Nov 2007 - Can''t run samples - Mac OS 10.3 w/ RubyGems

Hello -
     I''m interested in leveraging wxRuby on my PowerPC-based iBook.
I''ve got Mac OS 10.3.9 and I installed wxRuby 1.9.2 using gems.
However, when I try to run samples such as minimal.rb, I get the
following error:

dyld: ruby Undefined symbols:
_DataBrowserChangeAttributes
_PMGetDuplex
_PMSetDuplex
_TXNGetCommandEventSupport
_TXNSetCommandEventSupport
_TXNSetSpellCheckAsYouType
Trace/BPT trap

     It seems to be some fundamental issue with the install as I get the
same error no matter what sample I run.  It''s my understanding that I
don''t need to install any other libraries, but if I''ve
overlooked
something please let me know.  Thanks!


Sebastian.

I haven''t seen this error but I wonder whether it''s because
recent PPC
versions of wxRuby have been built using 10.4. I think, for example, 
that spell-check-as-you-type was a feature difference between 10.3 and 
10.4, and wxWidgets conditionally compiles support for this in.

The last binary that was built using 10.3 was preview-0.0.40. Perhaps 
you could try downloading it from:

http://rubyforge.org/frs/download.php/25570/wxruby2-preview-0.0.40-powerpc-darwin7.9.0.gem.old

Save the file, rename it to take the ".old" suffix off it, then run
"gem
install wxruby2-preview" in that directory, and also uninstall the 1.9.2 
gem.

If you can run the samples with that, then it is down to the OS version.

Unfortunately, in that case, you''ll have to compile your own version of
1.9.2, as, since my Powerbook got nicked, no-one in the dev team has a 
10.3 machine. Fortunately, installing from source is pretty routien on 
OS X - see the wiki:

Thanks Alex -
     I did try to build WxWidgets and during configuration it complained 
about not finding a recent enough version of GTK.  If you know a quick 
fix for that issue (command line switch for configure?) that would be 
great, but I think it''s simply time I shell out for a new OS version. 
:)  Thanks for your help!

It shouldn''t be looking for gtk on OS X, that''s for Linux. Is
there
--with-gtk in your configure flags? Check you''re using the right 
./configure switches from  
http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets

Hm, I re-downloaded the source today, and this time the configure (taken 
both times from the helpful link you mentioned) worked!  So I''m happily
compiling at the moment...Thanks for your help.
