SDL Library PNG support

Question

I tried compiling the code which I downloaded from net for one gaming application.

When I do configure I get the following error :-

configure: error: Unable to find the SDL_image library with PNG support

It seem to me that I did not had any SDL library on my fedora so I did the update as below :-

sudo yum install SDL

but I get the following output

Loaded plugins: refresh-packagekit

I tried googling this error but did not get any help.

Answer 1

For anyone who runs into this problem on Ubuntu or an apt-get environment:

sudo apt-get install libpng12-dev libjpeg8-dev libwebp-dev libtiff5-dev

Also, you may be hitting this if you've custom built SDL2 on your machine. In that case you'll also need to rebuild it to add the new features.

Answer 2

SDL_image is a separate module. You need to install its dev package individually. Installing SDL does not install SDL_image as it is an optional piece of the puzzle.

Answer 3

Do a yum install for libpng. Per the SDL Docs...

As of SDL_image 1.2.5, JPEG, PNG, and TIFF image loading libraries are dynamically loaded, so if you don't need to load those formats, you don't need to include those shared libraries. libpng depends on libz, and libtiff depends on both libz and libjpeg.
