sdl2_gfx compile avec succès mais donne une erreur lors de l'importation avec pysdl2

2016-11-01 1 views

J'ai écrit un petit script CMake pour construire SDL2_gfx sur Windows (la dernière frontière) dans un environnement Anaconda Python. J'ai fait de même pour SDL2 et pysdl2, et ils fonctionnent correctement. Cependant, le module sdl2_gfx imprime le message d'erreur suivant lors de leur importation:sdl2_gfx compile avec succès mais donne une erreur lors de l'importation avec pysdl2

>>> import sdl2 
>>> import sdl2.sdlgfx 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "C:\Anaconda3\lib\site-packages\sdl2\sdlgfx.py", line 63, in <module> 
    SDL_initFramerate = _bind("SDL_initFramerate", [POINTER(FPSManager)]) 
    File "C:\Anaconda3\lib\site-packages\sdl2\dll.py", line 87, in bind_function 
    (funcname, self._dll)) 
ValueError: could not find function 'SDL_initFramerate' in <CDLL 'C:\Anaconda3\Library\bin\SDL2_gfx.dll', handle 7ffb05e30000 at 0x1f703f544a8>

Je ne sais pas où chercher la source de ce problème, car il n'y a pas d'erreurs de compilation!

Pour être complet, voici mon CMakeLists.txt:

set(PROJECT_NAME "SDL2_gfx")

set(IS_LIBRARY true)

Rien hors de l'ordinaire, pour autant que je peux voir ?

Sous Windows, les symboles exportés doivent être marqués explicitement. SDL_gfx expectsDLL_EXPORT drapeau à définir lors de la construction dll.

Ajouter

set_target_properties(${PROJECT_NAME} PROPERTIES DEFINE_SYMBOL "DLL_EXPORT")

à votre fichier CMake.

Oui! Cela a fait l'affaire. Merci beaucoup. Je suis toujours un débutant avec CMake, mais je commence à l'aimer de plus en plus. –
