Problems with RUBY 1.8.2 and RUDL 0.8

[Glenn]

While learning RUBY a while ago I used RUBY 1.8.1 and RUDL 0.7.1 to
write pacman (just as a learning process) and all was well.

Now I've upgraded to RUBY 1.8.2 and RUDL 0.8 I get the following
message as soon as I run the game:

(eval):114: undefined method `print_centered' for class `RUDL::SFont'
(NameError)
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
`require'
from D:/PacMan/pacman.rb:10

Any ideas?

Yeah, this happened to me too. It's related to the new version of
RubyGems, but I haven't gotten a response about it yet.

The workaround is to use "require__ 'RUDL'" instead of "require RUDL"
- not a solution, but it will get you through until the bug is fixed.

I'm seeing this problem too.

I just built RUDL 0.8 from source; my Ruby is:
ruby 1.8.2 (2004-12-25) [i386-mswin32] (one-click installer)

I get the same thing as above. Here, from irb:

irb(main):001:0> require 'RUDL'
NameError: undefined method `print_centered' for class `RUDL::SFont'
from (eval):114
from C:/dev/ruby-1.8.2-14/lib/ruby/site_ruby/1.8/
rubygems/loadpath_manager.rb:5:in `require'
from (irb):1

irb(main):001:0> require__ 'RUDL'
=> true


Knowing nothing about RubyGems, I'm not sure what to make
of it. Looking at the RUDL code, the method SFont#print_centered
is defined at run-time by the C code, by evaluating ruby code.
It looks like:

void initSFontClasses()
{
classSFont=rb_define_class_under(moduleRUDL, "SFont", rb_cObject);
rb_define_singleton_method(classSFont, "new", sfont_new, 1);
rb_define_method(classSFont, "print", sfont_print, 3);
rb_define_method(classSFont, "size", sfont_size, 1);

add_sfont_print_centered(); // defines RUDL::SFont#print_centered

[...]
}

static void add_sfont_print_centered()
{
rb_eval_string(
"module RUDL class SFont \n"
" def print_centered(surface, y, text) \n"
" print(surface,[(surface.w-size(text)[0])/2,y],text) \n"
" self \n"
" end \n"
"end end \n"
);
}


Any Gems gurus out there have any thoughts? Anything you'd
like me to try? BTW, 'RUDL' is => RUDL.so, not RUDL.rb, if
that makes a difference.


Thanks,
