On my earlier version of the alarm clock I used the cl-sdl library. I was testing clbuild the other day and I tried to use its version of the sdl: lispbuilder-sdl. Unfortunately on my machine I was getting an error everytime the app was about to close the window due to a call to SDL-glue-SDL-Close-Audio method on the cffi part of the lispbuilder-sdl library:
I suppressed this message by calling a method I knew was working and it worked fine so far.
So if you want to try the same thing, look for the glue.lisp file on the clbuild/source
/lispbuilder-sdl/cffi and change this part to the following code:
So instead of calling the original method I am using the SDL_CloseAudio and it is working fine so far.
