Ferret talk - Apr 2007 - ferret-0.11.4-mswin32 not compatible with Ruby1.8.4

Just a quick note for future reference - at least for me, ferret won''t
work on Ruby 1.8.4.

gem install ferret
Successfully installed ferret-0.11.4-mswin32
ruby -v
ruby 1.8.4 (2005-12-24) [i386-mswin32]
irb
irb(main):001:0> require ''ferret''

A windows error message box appears -
ruby.exe - Entry Point Not Found
The procedure entry point rb_w32_write could not be located in the
dynamic link library msvcrt-ruby18.dll.

And the following shows in the command box.

LoadError: 127: The specified procedure could not be found.   -
C:/ruby/lib/ruby
/gems/1.8/gems/ferret-0.11.4-mswin32/ext/ferret_ext.so
        from

.so
        from

        from

        from
C:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:33:in `re
quire''
        from (irb):1

Works fine on a separate installation of 1.8.5.

Hi Sam,

This is unfortunate but it would probably work both ways. That is, if
I build it for 1.8.4 it won''t work with 1.8.5.

How many people are still using Ruby 1.8.4 and are having the same
problem? If there are enough of you I could build another gem
specifically for ruby 1.8.4. Actually, Sam, if you really need me to I
could build a special gem for you. Let me know.

Cheers,
Dave

I''m getting the following error trying to set the field_infos for an  
IndexWriter:

Ferret::Index is not missing constant FieldInfos! (ArgumentError)

here''s the code:

         @index_writer = Ferret::Index::IndexWriter.new(
                           :path     => my_path,
                           :create   => true,
                           :analyzer =>  
Ferret::Analysis::StandardAnalyzer.new,
                           :merge_count => 2,
                           :field_infos =>  
Ferret::Index::FieldInfos.load(IO.read(FIELD_INFO_FILE)))

I''m not sure what is causing the error. Any thoughts?

This is a bug in Ferret. I''ve fixed it but there is no need to wait
for the next release. Just include Ferret::Index at the start and
everything should work fine;

        include Ferret::Index
        @index_writer = IndexWriter.new(
                          :path     => my_path,
                          :create   => true,
                          :analyzer =>
Ferret::Analysis::StandardAnalyzer.new,
                          :merge_count => 2,
                          :field_infos =>
FieldInfos.load(IO.read(FIELD_INFO_FILE)))

That should fix your problem. Let me know if it doesn''t.

Cheers,
Dave

Thanks Dave. I''m still getting the same error after making that  
change. I''m using Ferret 0.11.3 on OSX. Thanks again.

Hi Erik,

Could you please try the following code and let me know if it works;

    require ''rubygems''
    require ''ferret''

    $fi = <<-EOF
    default:
      store: :yes
      index: :yes
      term_vector: :no

    fields:
      id:
        index: :untokenized
        term_vector: :no

      title:
        boost: 20.0
        term_vector: :no

      content:
        term_vector: :with_positions_offsets
    EOF
    include Ferret::Index
    @index_writer = Ferret::Index::IndexWriter.new(
                     :create   => true,
                     :analyzer => Ferret::Analysis::StandardAnalyzer.new,
                     :merge_count => 2,
                     :field_infos => FieldInfos.load($fi))

Thanks Dave, I will try this later. I ended up doing the following:

         field_infos = FieldInfos.new
         field_config = YAML.load(IO.read(FIELD_INFO_FILE))
         field_config.each_key do |field|
           field_infos.add_field(field, field_config[field])
         end
         @index_writer = IndexWriter.new(
                           :path     => settings.path,
                           :create   => settings.create,
                           :analyzer => settings.analyzer,
                           :merge_count => settings.merge_count,
                           :field_infos => field_infos)

Which appears to have worked.

Hey Dave, No need. I just happened to go to test something on the 1.8.4
Windows machine - I use Debian for production and have newer ruby''s on
other computers. I just pointed this out in case someone searched on
that ''problem''. Cheers for the offer though!
