Christian, Yes, ghc 7.7/7.8 *should* fix all the ghci linker related problems on platforms that support dynamic linking! If (or anyone else) finds problems with the ghci linker on 7.7, please report them post haste! I'm also glad to hear that someone's finally tested out the new ghci functionality properly! -Carter On Mon, Sep 16, 2013 at 8:52 AM, Christiaan Baaij < christiaan.baaij@gmail.com> wrote:

Hi,

I saw the same issue/crash on my machine using ghc 7.6.3.

I just build a "perf" build of GHC-head with "85a9e2468dc74b9e5ccde0dd61be86219fd323a2" as the latest commit.

Now running, I get: 1) > cabal install bindings-glfw 2) > ghci 3) ghci> :m Bindings.GLFW 4) ghci> Bindings.GLFW.c'glfwInit 5) ghci> 1

And doing: 1.) > cabal install GLFW-b 2.) > ghci -package GLFW-b 3.) ghci> import Graphics.UI.GLFW as GLFW 4.) ghci> GLFW.init 5.) ghci> True

My platform: - OSX 10.8.4 - ghc(i) 7.7.20130915 - cabal 1.18.0.1 (using 1.18.0 of the Cabal library) - xcode cltools 4.6.2

So it seems that the new ghci linking infrastructure fixes things

Cheers,

Christiaan

What I do for GLFW is use a dylib, then you don't rely on GHCi's static-ish linker. The only wrinkle is figuring out where you want the dylib. I think homebrew will put one in /usr/local/lib, which works out nicely, but they don't have GLFW 3 yet. Another option is to build the dylib yourself from the GLFW source bundled with the GLFW-b package, then tell cabal where to find it.

Hi, for me the problem relocates now to the "bindings-glfw" package, since the native bindings moved to this package and are wrapped up with "glfw-b".

My way to the same exception already mentioned by Brian Lewis: 1) > cabal install bindings-glfw 2) > ghci 3) ghci> :m Bindings.GLFW 4) ghci> Bindings.GLFW.c'glfwInit 5) ghci terminates with exception: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSAutoreleasePool init]: unrecognized selector sent to instance 0x7fc443c01b30'

Anthony Cowley mentioned to use ghci with GLFW as a dylib, I have no clue how to do this. I built the according glfw version on my own as a dylib and loaded ghci with it explicitly, this didn't help. I guess the compiled bindings-glfw is already statically packed up.

How can I get ghci to use the native glfw dylib in combination with bindings-glfw? If I have to compile bindings-glfw with different settings, which settings? I have some oversight over haskell but no really deep knowledge according to bindings and lib-loading of ghci, but I'm willing to learn it ;)

My Platform: - OSX 10.8.5 - ghc(i) 7.6.3 - cabal 1.18.0.1 - xcode dev tools 4.6.3
