wxruby users - Dec 2006 - Introduce and noob problem require ''wx''

Dear All,
my name is Raoul, this is the first time I post here.
I''m a computer scientis and I''m working in
bioinformatic''s filed, we have a
lot of tools to analyse the data but no good graphic applications to
visualize them. So I''m looking for a good framework for my job. I think
your
motivations on using wxruby are good, most important for me is the
crossplatform feature. I have to provide a good service for avery platform.
I''m interested on BioSQL too and probably in these days I''ll
star to code
some bioruby code to extend that library.
I hope wxruby2 will become stable as soon as possible.

I have installed wxruby2 by gems. then running the minimal application I got
this:

ruby -rubygems /usr/lib/ruby/gems/1.8/gems/wxruby2-preview-0.0.36-i486-linux
/samples/minimal/minimal.rb
Unable to load wxruby. Searched:
/usr/lib/ruby/gems/1.8/gems/wxruby2-preview-0.0.36-i486-linux/bin
/usr/lib/ruby/gems/1.8/gems/wxruby2- preview-0.0.36-i486-linux/lib
/usr/lib/ruby/site_ruby/1.8
/usr/lib/ruby/site_ruby/1.8/i586-linux-gnu
/usr/lib/ruby/site_ruby
/usr/lib/ruby/1.8
/usr/lib/ruby/1.8/i586-linux-gnu

I''m quite sure the error is stupid but I can''t see it...


Tnx a lot.

RJP

It looks like ruby is running into a problem when it tries to load the 
compiled library file which contains the bulk of wxruby2 functionality. 
Can you first verify this file exists? - according to the output you 
have shown I think it should be at:
/usr/lib/ruby/gems/1.8/gems/wxruby2- 
preview-0.0.36-i486-linux/lib/wxruby2.so

If this file does exist, could you try seeing if it will load on its own:
ruby -rubygems -e "require ''wxruby2''"

And report any error messages. Could you also let us know what distro 
you''re using, and what GTK2 libraries you have installed on your
system,
with versions (eg libgtk2.0, libgtk2.0-dev)

thanks
alex

Yes, this sounds like the problem, but I am not quite sure why. The 
''official'' builds are supposed to use wxwidget''s
built-in versions of
libtiff, libpng, libjpeg. I wonder if there is a problem b/c you *do* 
have your own version of libtiff installed, but it isn''t compatible for
some reason. Sorry I can''t check this as away from home so
don''t have a
linux machine.

Anyway, we are looking to do a release shortly; if it''s OK, I will 
contact you off list about trying a pre-release compiled linux version.

Thanks again for the report
alex

That''s fine for me.
