SDL image/libpng/VS2010

Hi.
I’ve just a “simple” question. How am I to interpret this error message? I’ve tried googling a lot of permutations but the closest I’ve gotten is about SDL and VS settings which I know are set correctly (I can load bmps, gifs AND jpegs for instance and jpeg.dll is in the same folder and libpng12-0.dll, but as soon as I change the path to point to any png-image I get the error message below)

"IMG_Load: Failed loading libpng12-0.dll: %1 is not a valid Win32 application."
SDL 1.2.14
SDL 1.2.10 (obviously)
VS2010

Hi

I assume you’ve called IMG_Init(IMG_INIT_PNG) ?

But that error message is something more fundamental. Did you recompile the libraries yourself? Also, just make sure that Configuration Type in your project properties->general is set to static library, and not application (.exe). Basic, but you’d be surprised how many people change this and wonder why nothing works.

ehm…actually no (I’m too embarrassed to say why) but it works without IMG_Init anyway.

Yup, you were right, seems I was missing zlib, which I don’t understand why the error message didn’t mention (I used the dlls from SDL_Image VC).

Anyway, thanks for your help. I haven’t used SDL before so I didn’t know what to think of that error message.
