Preferred SDL2 library method for installation on OSX #73

Closed fud closed 6 years ago

fud commented 8 years ago

I have tried to install SDL2 via homebrew and also downloaded the dmg for SDL2 from the webpage and installed it in /Library/Frameworks/ but I get issues.

I'm using ccl 1.11-r16635 with quicklisp installed. I'm getting this,

? (ql:quickload "sdl2")
To load "sdl2":
  Load 1 ASDF system:
    sdl2
; Loading "sdl2"
> Error: Unable to load any of the alternatives:
>           ((:FRAMEWORK "SDL2") (:DEFAULT "libSDL2"))
> While executing: CFFI::FL-ERROR, in process listener(1).
> Type :POP to abort, :R for a list of available restarts.
> Type :? for other options.

Odd. I've confirmed people have recently installed via the frameworks method and it is loading normally. One suggestion was to confirm /Library/Frameworks has SDL2.framework (not SDL.framework), but... otherwise this should be a no-brainer I think, but I'm not particularly familiar with the OSX end of things.

I double checked and it's SDL2.framework as you said. Maybe someone with OSX experience can chime in.

Easiest way (IMHO) to deal with SDL (either 1 or 2) is via homebrew. All Lisps (Scheme or CL) will find and use easily the SDL libs and headers from homebrew, or GL/GLFW etc... I always too had trouble with the Framework packages.

@paines Interestingly that's what I did originally and it didn't work. People on the #lisp channel on freenode suggested I try frameworks. I might uninstall Clozure CL and ~/quicklisp/ and reinstall everything.

@fud Did you use sbcl/ccl from brew together with SDL from brew?

fud commented 8 years ago

@paines Yes I usually do everything through homebrew actually unless there isn't anything available.

Is this still an issue?

fud commented 6 years ago

I didn’t get any further and gave up.
