i'm pretty sure they're usable in ghci... i think theres just certain flags that need to be invoked for one reason or another, but I could be wrong (and i've not tried in a while) On Tue, Oct 21, 2014 at 2:58 PM, George Colpitts wrote:

Along the lines of making GHCi better it would be very nice if we could use SDL, OpenGL etc in GHCi.

Is there a characterization of the libraries that we can't use in ghci?

As you know this has been a problem for years. Is there an open bug about it?

I know there was some hope that dynamic linking in 7.8.3 would fix this. What has been your experience?

For some reason I get mail to ghc-devs but can't send mail to the mailing list.

Thanks George

Good evening,

For years I’ve been using GHCi as a base and it’s been very reliable for almost every project I’ve done (the only exceptions are things like SDL and OpenGL, which are well known to be difficult to load in GHCi, at least on Linux). I think we’ve built up a good set of functionality https://github.com/haskell/haskell-mode/wiki/Haskell-Interactive-Mode purely based on asking GHCi things and getting it to do things.
