[sdljava-users] Re: Problems with SDLJava_Image.dll and jpeg.dll

[Patric <pa...@ma...>]

Hi list,

I finally figured out the problem:
It is a dll collision with the jpeg.dll from SDL and the one at the 
JRE/bin folder.

My solution was renaming the SDL jpeg.dll and patching the SDL_Image.dll 
import table that it points to the new name.

Maybe we should consider contact the SDL_Image team that they think 
about renaming of the jpeg library.

Best regards
Patric
