Re: [Haskell-cafe] How to use Plugins package?

I tried this and all other examples I could find. They didn't work. I hadn't find any explanation yet. And I don't know how I can get more information about errors. I believe Plugins uses GHC API internally. Нowever code like [1] works well for me on Linux and Windows. I think I'll stay with this approach for a while. What limitations does it have? I appreciate your help. It would be nice to understand what prevents me from using Plugins. [1] https://github.com/jgm/gitit/blob/master/Network/Gitit/Plugins.hs 2012/5/18 Jeremy Shaw :

plugins-auto has a demo in the darcs repo:

http://www.patch-tag.com/r/facundo/plugins-auto/snapshot/current/content/pre...

Does that work for you ?

Hi,

I'm newbie and I've got a problem.

I'm trying to get example programs from plugins-auto [1] or hotswap [2] to work. I think question on stackoverflow [3] somewhat related to my problem.

They are compiled well, but in runtime I get either segfault or Prelude.undefined or internal error: PAP object entered!

I use GHC 7.4.1. x86_64 Ubuntu

I've read "Plugging Haskell In" and would like to make some fun with plugins, but alas...

Maybe -dynamic flag is what I seek? Or maybe I need to know something else? Maybe I needn't use Plugins package like in gitit?

Please, could you explain how to compile plugins in haskell correctly? Where should I start?
