lispbuilder-sdl doesn't work on osx due to sdl_delay - macos

Question

my operate system is OS X 10.11.5, code with emacs+slime+sbcl
I loaded lispbuilder-sdl using command:
(asdf:operate 'asdf:load-op :cocoahelper)
(asdf:operate 'asdf:load-op :lispbuilder-sdl)
then copy the example code on here
(sdl:with-init ()
(sdl:window 320 240)
(sdl:update-display)
(sdl:with-events ()
(:quit-event () t)))
but nothing happened,so i type 'C-c C-c' to terminate the process,
it shows some error like this:
Restarts:
0: [CONTINUE] Continue from break.
1: [RETRY] Retry SLIME REPL evaluation request.
2: [*ABORT] Return to SLIME's top level.
3: [ABORT] abort thread (#<THREAD "repl-thread" RUNNING {1003FC0003}>)
Backtrace:
0: ("bogus stack frame")
1: ("foreign function: SDL_Delay")

7: (EVAL (LISPBUILDER-SDL:WITH-INIT NIL (LISPBUILDER-SDL:WINDOW 320 240) (LISPBUILDER-SDL:UPDATE-DISPLAY) (LISPBUILDER-SDL:WITH-EVENTS NIL (:QUIT-EVENT NIL T))))
Is there anyone can help me fix this error?

Answer 1

I tried to reproduce your example (Linux/SBCL). First:
(ql:quickload :lispbuilder-sdl)
Then:
(sdl:with-init ()
(sdl:window 320 240)
(sdl:update-display)
(sdl:with-events ()
(:quit-event () t)))
This displays an empty window while the REPL hangs (as expected), until I close the window and can use the REPL again. But if I do C-c C-c while the window is displayed, then I obtain a stack trace similar to yours:
Interrupt from Emacs
[Condition of type SIMPLE-ERROR]
Restarts:
0: [CONTINUE] Continue from break.
1: [RETRY] Retry SLIME REPL evaluation request.
2: [*ABORT] Return to SLIME's top level.
3: [ABORT] abort thread (#<THREAD "repl-thread" RUNNING {1003498033}>)
Backtrace:
0: ("bogus stack frame")
1: ((SB-PCL::EMF LISPBUILDER-SDL::PROCESS-TIMESTEP) #<unavailable argument> #<unavailable argument> #<LISPBUILDER-SDL:FPS-FIXED {1006F962A3}> #<FUNCTION (LAMBDA NIL :IN #:DROP-THRU-TAG-1) {1006F95F0B}>)
2: ((:METHOD LISPBUILDER-SDL::PROCESS-TIMESTEP :AROUND (LISPBUILDER-SDL::FPS-MANAGER T)) #<LISPBUILDER-SDL:FPS-FIXED {1006F962A3}> #<FUNCTION (LAMBDA NIL :IN #:DROP-THRU-TAG-1) {1006F95F0B}>) [fast-metho..
3: ((LAMBDA ()))
4: (SB-INT:SIMPLE-EVAL-IN-LEXENV (LISPBUILDER-SDL:WITH-INIT NIL (LISPBUILDER-SDL:WINDOW 320 240) (LISPBUILDER-SDL:UPDATE-DISPLAY) (LISPBUILDER-SDL:WITH-EVENTS NIL (:QUIT-EVENT NIL T))) #<NULL-LEXENV>)
5: (EVAL (LISPBUILDER-SDL:WITH-INIT NIL (LISPBUILDER-SDL:WINDOW 320 240) (LISPBUILDER-SDL:UPDATE-DISPLAY) (LISPBUILDER-SDL:WITH-EVENTS NIL (:QUIT-EVENT NIL T))))

However, everything is working as expected, because I can for example choose to continue the execution, or abort. That's what the interrupt is for.
My guess is that everything works fine but you can't see the window. I don't know why and I have no experience with OS X, unfortunately. Maybe if you try to actually display something (see below), as recommended in SDL window does not show, it could work.
Here is an example which draws something:
(sdl:with-init ()
(sdl:window 320 240)
(sdl:update-display)
(sdl:with-events ()
(:quit-event () t)
(:idle (sdl:fill-surface sdl:*white*)
(sdl:update-display))))
