nim-lang / sdl1 Goto Github PK

I'm not 100% sure this is related to the binding, but I'm also not really sure why I can't get this to work.

When I use https://github.com/nim-lang/sdl2/blob/master/src/sdl2/mixer.nim, I am able to play an mp3 file. With the exact same code, but using the sdl_mixer in this repository, I get Unrecognized music format printed out. I believe this means I have all of the dynamic libraries properly installed and configured, otherwise I wouldn't be able to get SDL2 to work.

import sdl
import sdl_mixer
discard sdl.init(INIT_EVERYTHING)
discard openAudio(22050, AUDIO_S16SYS, 2, 640)
var music = loadMus("music.mp3")
echo getError()
discard music.playMusic(1)

EDIT:
I tried reproducing a similar example in C, and noticed the Mix_Init function (which this wrapper omits, but the SDL2 wrapper has this function). After running that and checking for errors, I get Mix_Init: Mixer not built with MP3 support. Not sure if this is solvable on the end of this wrapper, but I'm also not sure if the Mix_Init function needs to be wrapped.

/home/david/.nimble/pkgs/sdl1-1.0.0/sdl.nim(1064, 27) Error: undeclared identifier: 'expr'

I think it comes from use of 'expr' in this template:

template evconv(procName: expr, ptrName: typedesc, assertions: EventSeq): stmt {.immediate.} =
  proc `procName`*(event: PEvent): ptrName =
    assert(contains(assertions, event.kind))
    result = cast[ptrName](event)
