# jruby-1.6.6/lib/ruby/site_ruby/shared/ffi/library.rb" line 154
raise FFI::NotFoundError.new(cname.to_s, ffi_libraries.map { |lib| lib.name })
{noformat}
The code above is passing an array to FFI::NotFoundError#initialize(function,
*libraries)
The following monkey patch to jruby-1.6.6/lib/ruby/site_ruby/shared/ffi/ffi.rb
seemed to resolve the issue for me.
{noformat}
require 'ffi'
module FFI
class NotFoundError < NativeError
def initialize(function, *libraries)
libraries.flatten!
super("Function '#{function}' not found in [#{libraries[0].nil? ?
'current process' : libraries.join(", ")}]")
end
end
end
