libxml-ruby-5.0.6 does not work at all

[arnej27959]

OS: AlmaLinux 8, 9, 10 - all fail
ruby version: 3.1.7p261, 3.3.10 - both fail
Note: libxml-ruby version 5.0.5 works without any problems.

From plain AlmaLinux 10, after

  dnf -y install gcc libxml2-devel
  dnf -y install libffi-devel         ruby         ruby-devel         rubygems         rubygems-devel
  gem install libxml-ruby

This is the failure output:

require 'xml'

[root@7d7efb49b6ac tmp]# ruby t.rb

Does the file exist?

/usr/local/share/gems/gems/libxml-ruby-5.0.6/lib/libxml_ruby 

If yes, could you try reverting this locally:

53404f7

Thanks

[arnej27959]

no;
but reverting 53404f7 fixes the problem here anyway.

I guess the problem is that the shared library isn't anywhere nearby libxml-ruby.rb, so require_relative doesn't work.
Here are some relevant paths:

# find /usr -name 'libxml*ruby*' 
/usr/local/lib64/gems/ruby/libxml-ruby-5.0.6
/usr/local/lib64/gems/ruby/libxml-ruby-5.0.6/libxml_ruby.so
/usr/local/share/gems/cache/libxml-ruby-5.0.6.gem
/usr/local/share/gems/doc/libxml-ruby-5.0.6
/usr/local/share/gems/gems/libxml-ruby-5.0.6
/usr/local/share/gems/gems/libxml-ruby-5.0.6/ext/libxml/libxml_ruby.def
/usr/local/share/gems/gems/libxml-ruby-5.0.6/ext/vc/libxml_ruby.sln
/usr/local/share/gems/gems/libxml-ruby-5.0.6/lib/libxml-ruby.rb
/usr/local/share/gems/gems/libxml-ruby-5.0.6/libxml-ruby.gemspec
/usr/local/share/gems/specifications/libxml-ruby-5.0.6.gemspec

Hmm, can't say I understand why /usr/local/lib64/gems/ruby/libxml-ruby-5.0.6/libxml_ruby.so would exist. And why that doesn't show up in the test runners. I'll see if the tests still pass reverting 53404f7.

Ok will be fixed in 6.0.0. Thanks for the report!
