Undefined symbol: _png_set_longjmp_fn

SDL Development
1

I’ve just downloaded and compiled the newest releases of SDL and SDL_image
on Fedora 17. I can’t seem to load PNG files with IMG_Load. The error
message is:

png_set_longjmp_fn: /lib64/libpng.so.3: undefined symbol:
_png_set_longjmp_fn

I’m no libPNG expert so I’m not sure what’s causing this. Does anybody else
know?

I avoid this problem for ubuntu 12.04 using:

sudo apt-get install libjpeg-dev
sudo apt-get install libpng-dev
sudo apt-get install libtiff-dev

but now when I try to open a PNG I get other error:

LoadTexture error: Couldn’t open res/Lesson3/background2.png

from source code:

//we create the textures from images
SDL_Texture *background = loadTexture("res/Lesson3/background2.png",

renderer);–

Are you absolutely certain that the file path is correct?On Tue, Sep 10, 2013 at 9:32 PM, alshira wrote:
