Hi.

I’m trying to run some pre-1.9 code along these lines:

require ‘dl/import’

module C  
extend DL::Importable  
end

However I’m getting an ‘uninitialized constant DL::Importable  
(NameError)’.

Is DL::Importable defined differently in 1.9 or am I being stupid? I’m  
running the code on OS/X.

Many thanks.

Steve

Yep it’s changed. For me this meant I had to update my net/ssh gem to  
the latest version, so looking at net/ssh’s commits might yield some  
clues.

Anybody can post something helpful in that regard?  
thanks.

Quick update after poking around in the dl folder in ruby/lib.

DL::Importable is gone. Use DL::Importer instead.

You can’t pass nil into methods, I had to use DL::TYPE\_VOID (something  
like that, can’t remember exact syntax off top of my head).

I had to change a few things to CPtr, which I assume is new, to get them  
to work.

In conclusion if you have any dl code written for Ruby 1.8 - update to  
DL::Importer and you should be able to fix the rest using the error  
messages.
