Hello,

It's my pleasure to inform you that Ruby/DL2 has come out.

http://rubyforge.org/projects...

I made it work with both of ruby-1.8 and ruby-1.9. Please try
it and let me know what you think except for incompatibility
between Ruby/DL and Ruby/DL2. I have a plan to replace Ruby/DL
of ruby-1.9 with Ruby/DL2 after hearing serveral opinions.

Best regards,

P.S.
I'd like you to read test/test_import.rb instead of a tutorial,
since there is no documentation about Ruby/DL2.

Thanks for giving this to ruby 1.8!

I wasn't going to read this post because I assumed it'll only be for
Ruby 1.9. Glad I did!

Installing with ruby 1.9.0 (2005-01-27) [i686-linux],

(NB: At this point callback.h exists.)

If we run make again, the build succeeds but trying to require 'dl' produces
irb: relocation error:
/usr/local/stow/ruby-cvs//lib/ruby/site_ruby/1.9/i686-linux/dl.so: undefined
symbol: rb_dl_init_callbacks

Apart from fixing the bug is causing the error, I guess mkcallback.rb
should delete callback.h if an exception reaches the top-level.

The actual bug in question is caused by the line
return #{DLTYPE[ty][:conv] % "ret"};

Most of the time we have things like
INT => {
:name => 'int',
:type => 'int',
:conv => 'NUM2INT(%s)',
}

but there is also

VOID => {
:name => 'void',
:type => 'void',
:conv => "",
}

Thanks for all your work. Ruby/DL has long been my favourite Ruby extension
:-)

I think you run ruby-1.9 with the option '-d' or '--verbose'.
I modified mkcallback.rb, fixed another problem and released ruby-dl2-0.1.zip.

Thanks,

Yes, I have "RUBYOPT=-w".

ruby-dl2-0.1 builds fine and running test/test_all.rb produces
28 tests, 43 assertions, 0 failures, 0 errors

Thanks.
