Hi,
I'm playing around with ffi and stumbled over a strange error:

module XosdRaw
    extend FFI::Library
    ffi_lib 'xosd'
    enum :command, [:percentage,:string,:printf,:slider]
    attach_function :xosd_display,
[:pointer,:int,:command,:varargs],:int
end

gets me this error:

ruby: symbol lookup error: /home/popel/.gem/ruby/1.8/gems/ffi-0.6.3/
lib/ffi_c.so: undefined symbol: rb_intern2

it seems that the lookup of type fails. I patched types.rb

def self.find_type(name, type_map = nil)
    type_map = TypeDefs if type_map.nil?
    code = type_map[name]
    code = TypeDefs[name] unless code  #<------added this line
    code = name if !code && name.kind_of?(FFI::Type)
    raise TypeError, "Unable to resolve type '#{name}'" unless code
    return code
end


Now it works. I don't know if this is the right way (perhaps I did
something completly stupid) but perhaps some of you can have a look at
this.

THX
