Using DevC++, I added -lSDL_image to the parameters of the linker. Although, evertything seems to be installed correctly (SDL_image 1.2.3 from devpaks.org), I get the following error message: ld.exe (...) cannot find -lSDL_image Does anyone know what's the problem? Regards, T.

is the sdl_image.dll file in your windows/system32 folder?

Nope, it's not.

The SDL_image file resided within the C:\Program Files\Dev-Cpp\Dll folder as the SDL.dll does, too.

However, I thought this is no point here, since I am trying to statically link to SDL?

Isn't the -lSDL_image flag supposed to link against the SDL_image.a library which is located in the C:\Program Files\Dev-Cpp\lib folder?

the -lSDL_image flag links to libSDL_image.a library.
AFAIK SDL_image packadge from devpaks is broken. download its sources and build the binaries yourself or get mine ( here )

Some time ago I also tried to do -lSDL_Image stuff in DevC++ but it didn't worked. Then I tried explicitly saying where that lib is stored through full pathname (Project settings -> Parameters -> Linker) and now it's working.

Thanks a bunch, I used your package along with putting the -lSDL_image flag in the Project -> Project Options -> Linker parameters. It compiled correctly, but it doesn't seem load image files correctly (BMPs or PNGs). Any clue why?

image = IMG_Load("image.bmp"); // or image.pngif(image == NULL){	fprintf(stderr, "Unable to load image: %s\n", IMG_GetError());}

It always outputs:

Unable to load image: Unsupported image format

I've tried playing around with putting the libpng1.dll and zlib.dll everywhere and no success.

have you tried solutions from this thread ?

i use the img_load function to load textures this way:

    SDL_Surface *img;    img = IMG_Load(filename);    if(!img) cout<<IMG_GetError()<<endl;    SDL_LockSurface(img);                //..Opengl stuff here..    SDL_UnlockSurface(img);    SDL_FreeSurface(img);

and i have not had problems with 24 and 32BPP images (PNG,TGA,BMP)

//edit:also, assure that your application use sdl_image.dll file from my package.
